Among them, squid is a high-risk product for the detection of gas ash and abundance of metabolites; the squid does not conform to the prescribed drug project as a meta- sulphuric acid and nitrofuran metabolite; Wu Guoyu is chloramphenicol and reduced malachite green ; squid and grouper # is a nitrofuran metabolite and a reduced type of malachite green. According to the above information, the pre-existing food for animal use is very high, and the test will continue to be carried out to protect the health of Chinese people. The side of the eye to detect aquatic products is liquid chromatography mass spectrometry (LC/MS/MS), which has a sensitivity of about a few PPb (~1G) for various animal drug residues. Animals_residues are performed using LOMS/MS. Although the second precision 'but in the fine business, there are still many _; if the aquatic products obtained must be complicated and lengthy (four) New Zealand, then the amount of LC / Ms / Ms can be made _ residual = = LCMS / MS The operation 'must be in the environment of 2〇_25 〇c, so a special = room is required to place the LC/MS/MS; the precise operation and maintenance of the LC/MS/MS is not easy, so it is necessary to hire Jing: The position has been _丨_人贞, full-time 贞 (4) as a paver, invisible _ the technology ^ application level, also increases the cost of testing. With IT research team wants to use EL and other existing technologies for animal music residue test 'but often Due to the complexity of the operation at the time of detection, or the excessive false negative of the pseudo-yang, the technology has been widely promoted, and this is still expected to be able to open up in the market - the detection technology for animals used in aquatic products In order to meet the needs of the market. [Invention content] ==_编_纯嶋(四)Touch, including ·Multiple magnetic 2011 20445 an active agent layer coated on the magnetic core, and the animal drug antibody to be tested 'bonded to the surfactant layer. The magnetic core referred to herein includes materials including but not limited to Fe3〇4, FeA, paralysis, C〇Fe2〇4 and NiFe2〇4, in a preferred embodiment, the magnetic core material & heart 4. The term "surfactant" as used herein refers to the surface of the target solution. A substance whose tension is significantly lowered, and a substance which lowers the surface tension between the two liquids. The surfactant is generally a hetero- and amphoteric molecule having a hydrophilic and a hydrophobic group, and is soluble in an organic solution and an aqueous solution. The surface active material used includes, but is not limited to, an organic acid, a protein A, a protein fg, a vinegar or a oligosaccharide. In a preferred embodiment, the material of the surfactant is vinegar. In the test, the animal drug system includes, but is not limited to, pneumomycin (4) (4) coffee CAP), fine ring mycin, gas tetracycline, deoxytetracycline, tetracycline, zhubo, and Kaba fine, beta-receptor, Kong He, Gu-type malachite green Silk material metabolites and what φ = (Q olone) class in the preferred embodiment, the present invention is of animal drugs for the gas detection element emblem. The sirloin referred to herein is any edible animal. In the more preferred embodiment, the animal is an aquatic animal. In a more preferred embodiment, the aquatic animal is a shrimp. Shuming also provides a method for detecting animal_residue in food, comprising: providing animal medicine for extracting the body in the invention, mixing the extract with the reagent, measuring the magnetic reduction signal, comparing and measuring the drug The magnetic decrement signal standard curve is used to quantify the residual amount of animal bribes. 201120445 Since the magnetic dipole direction of each magnetic core in the direction of the magnetic dipole is the direction of the ^, because of the thermal motion, each, therefore, the probability of the detection agent without the applied magnetic direction is - When the exchange changes, , ' does not show impurities. When the external magnetic field is applied, the reagent is generated by the girl due to the magnetic action, and will rotate with the external alternating magnetic field due to the biochemical rate. (4) The sample of the test fiber is mixed with money. The anti-animal drug antibody will be mixed with the sputum sample towel m, and the product will become large, P骇1 age, and the nanoparticle particles will be finely _touched + 嶋. Domain-to, will make the blood and oil combined with the magnetic Naizi can no longer rotate with the magnetic field of the material, and create a ^^; therefore, paste (four) her face _ substance medication, the magnetic nano-particles combined with it, so that The more the AC susceptibility of the reagent is reduced. Because the amount of magnetic susceptibility of the 2nd inspection product is reduced, the animal's _magnetic reduction signal can be compared to the residual amount of animal medication. In order to cooperate with the method of the present invention, the present invention further provides a method for extracting an in vivo __ drug, the steps of which are: (1), the sample is made into a mud, (2), and the extract is extracted and centrifuged to leave The supernatant, (3), using the low-pressure true hair method (using the pumping pump to assist the evaporation of the extract), the supernatant is concentrated, and (4), the lion age test concentration test. The extract in the present invention is an organic solvent. In the preferred embodiment, the extract is acetic acid. In a preferred embodiment, the diluent is dimethyl sulfoxide and a phosphate buffer. If a better extraction rate is desired, step (2) can be repeated multiple times to increase the extraction rate. This extraction method takes about (9) minutes, and the current extraction procedure for LC/MS/MS takes about (10) minutes, greatly reducing the extraction time and eliminating the need for complex extraction steps with n-hexane. The extraction procedure developed by the present invention can effectively improve extraction aging and increase the ease of use of the extraction procedure compared to current extraction procedures for LC/MS/MS. And the instrument used in this extraction procedure is relatively simple. 201120445 For example, the current secret LC/MS/MS extraction gamma depends on the fine sharp machine (which is not required to be used in the extraction procedure of the present invention, but is replaced by a simple pump. Checking the transcript will also help to promote the use of the secret drug in the future. The method for detecting the food cap of the present invention, the animal axis heat includes but is not limited to pneumomycin, cyclosporine, gas tetracyclic Taxomycin, tetracycline, tetracycline, norepine, naicarbamate, b-bubble, perforation, occupational Weiqian, nitro-methane metabolite and quinolone Quinolone The animal drug of the preferred embodiment is chlorin. [Embodiment] The following implementation tanks represent several unique secrets of the present invention and are summarized in the first embodiment. The reagents are synthesized to synthesize ferrous sulfate heptahydrate (called 7 shame) with a stoichiometric ratio of 1:2. The side effect of the mixed iron solution of the gasified iron shovel (10) is dispersed as water as a surfactant of ruthenium tetroxide. The mixture was heated to Μ·9 test: black iron oxide particles were formed. The plexus and the excess __ are removed by centrifugation and the sputum is too thick. The 'di-acid salt buffer dilution has been obtained at the appropriate concentration. Yang-7. In order to make the anti-hearing to the Nai Nai (4) (4) (4), as the example of the alizarin anti-shock 201120445 (Ab35658 - 500, Abeam), add the NaI〇4 solution to the magnetic solution to oxidize the glucan to obtain The aldehyde group (-CHO) 'after' glucan can react with the anti-chloramphenicol antibody through the linkage of the team, so that the anti-chloramphenicol antibody can be covalently linked to the glucan, as shown in Figure _ω Show. The unconjugated anti-pneuxin antibody can be magnetically separated and removed from the solution, and the reagent can be combined with the sample to be tested in the sample to cause a decrease in magnetic susceptibility, as shown in Fig. 1(b). Using a magnetic force microscope (MFM), the particle size distribution of the magnetic particles in the synthesized gastrin detection reagent was measured as shown in Fig. 2. The average particle size is in the excitation, and the standard deviation is 3.5 nm. In order to determine the magnetic hoof table®, there is a secondary antibody that binds to the surface of the magnetic particle, as shown in Figure 3(a). In the experiment, an excess of FITC was added; the graded antibody was mixed with magnetic particles coated with a gasmycin antibody. After thorough mixing, the magnetic particles in the mixed solution are separated by a magnetic separation technique, and the FITC secondary material which is not bonded to the magnetic particle fine test antibody is left in the original mixed solution. The separated magnetic particles were redispersed into the pBS solution. Since the fluorescent marker FITC can absorb 495 run wavelength of ultraviolet light and divergence 528 lung wavelength green light, so the solution is placed under the #microscopic observation, first green highlights, such as the anus (9) towel arrow At the office. This exemption is the light emitted by FITC. Next, place a magnet next to the solution. At this time, the magnetic particles in the solution are attracted by the magnet and move. Even if the surface of the magnetic particles is attached to the gas-enhanced antibody, the secondary antibody with FITC should be attached to the magnetic surface of the magnetic beads. When the magnetic beads are employed, then the green shell points observed in Figure 3 (9) will also move in the direction of the magnet. In this embodiment, the magnet is placed in the lower part of Figure 3, and the magnetic particles should be touched underneath, so the green highlights of Figure 3 are also moved downward. This 201120445 prediction is observed in Figure 3 (C). It was confirmed that the magnetic particles were indeed attached to the gas-mycin antibody (Anti-CAP) °. The magnetic reduction standard curve of the gas content of Example 2 was established to establish different amounts of chloramphenicol (C1863-25Q Sigma) dissolved in pH-7.4. The acid salt buffer is used to obtain standard gasmycin solutions with different concentrations ranging from 0.1 ng/g to 30 ng/g. The standard gasmycin solution of each concentration is subjected to three repeated magnetic reduction (IMR) tests. The test methods are as follows: 40 μΐ of magnetic reagent was mixed with 60 μl of different concentrations of standard gasomycin solution in a glass tube. The magnetic reagent used for IMR detection was 0.1 emu/g (= 5 mg-Fe/ml). The instrument (Xacpr0-El〇l, MagQu) measures the XaeQ AC signal before binding to chloramphenicol-anti-chloramphenicol antibody-dextran-nano magnetic particles, and the mixture of different concentrations forms at room temperature. Chloramphenicol-anti-chloramphenicol antibody-dextran _ nano magnetic particles, measuring and recording its exchange letter For the χ^, φ, the measured value of the transmission, and χ^φ, the IMR signal can be calculated by the following formula: IMR (%) = (χΜ, .- χΜ)/χκ, X 100 % for each For a given concentration of the sample solution, the time-dependent Xac AC signal is detected for three repetitions. φ The experimental image of the IMR signal as the gasmycin concentration ((J)Cap) is obtained as shown in Fig. 4. The IMR signal can be seen in Figure 4. As the concentration of chloramphenicol decreases, the concentration of chloramphenicol is low when the IMR signal analyzed by the magnetic immunoassay analyzer (XacPro-ElOl, MagQu) is nearly random (about 0.82% of the dotted line) At 0.1 ng/g. From the previous test results, the concentration of the analyte and the IMR signal meet the following Logistic Function AB IMR(%) =

And β is a parameter of the function. Putting the experimental data into the logical function, you can get Α=0.81, Β=4.54, φ〇=60.4 and β=0.61, and draw them in Figure 4 in solid lines. The correlation coefficient between the experimental data and the logistic fimction is r2=0.98, which shows that there is a high correlation between the two, and it is obvious that DVIR-(j)cAP is a logical special function. Example III IMR Interference Test for Pneumomycin Since foods do not necessarily contain only one animal drug, it is necessary to test whether different animal drugs are used, and whether it interferes with the detection of IMR. In this example, other typical animal drugs such as malachite green (MG), reduced malachite green (LMG), and 3-alcohol-2 - chemozolidone (AOZ, Fulton's metabolism) were used. , sulfamethylpyrimidine (SMR), and hydroxytetracycline (〇TC) were used as IMR interference tests for chloramphenicol. The concentrations and numbers of the six solutions are shown in the table below, and the phase (f) concentration of the kiss is added to its t. In addition to job 1, the liquid interference substances are added to IGng/g to dissolve money. Then, the anti-testin antibody reagent was used to test the IMR signals of the six solutions, as shown in Figure 5. According to the (4) series, the value of the solution between the solution and the solution is 0.74, the solution #1 and the solution are about _ household value is 23 23, the ρ value between the solution and the solution is 0.38, solution #1 and solution #5 The ρ value of 帛 is 〇42, and the reduction between the solution remedy solution is 〇.25. According to the T test statistics, when the value of ρ is large, it means that there is no significant difference between the two communities. There is no significant difference between the magnetic enchanters and the silk weights. When the shame's rhythm is used, it will not be affected by other animal medications. 201120445

Take shrimp as an example. After removing the shell of the shrimp, pour the shrimp into a mud (10 minutes), add 6 ml of the extract of ethyl acetate and mix with 1 gram of meat. After 3 minutes, centrifuge 5 times. The supernatant was obtained at rpm for 5 minutes, and chloramphenicol was the supernatant in most of the meat. In order to increase the extraction rate, the step of adding the extract may be repeated a plurality of times. The supernatant is concentrated by a low-pressure vacuum evaporation method, and the dried product is dissolved in a dilute solution of a dimethyl group and a salt buffer, which is a sample which can be directly detected by the machine. This extraction method takes _ (10) minutes to extract and edit the extraction time. In order to check whether the extraction method can extract the residual chlorophyll in the shrimp meat, 100 ng of gasmycin was added to the mud to simulate the meat containing 10 ppb of chloramphenicol. After the extraction procedure of Figure 6, use New Zealand _, the rhyme trace 4 re-touch the green amount _ fruit is 臆❶ / % ° according to Figure 4 _ prime test _ curve, the magnetic decrement signal to the concentration of the Gu, nuclear _pb , which indicates the extraction process of Figure 6 and the extraction rate can reach about (4). If the procedure of the ethyl acetate extraction step is increased, the extraction rate can be further increased. 201120445 [Simplified description of the drawings] Figure 1.
