Description
Technical field
The present invention relates to metal electrode field, more particularly to a kind of preparation method of metal electrode.
Background technology
Diabetes are a kind of very universal in the world and endanger very big chronic disease, ID（International
Diabetes Federation, IDF）Newest report shows, about 60 years old of half in 2013
The cause of the death of following dead adult is diabetes；And the morbidity crowd of diabetes is still increasing year by year.Current medical science skill
For art also without the effective ways that can cure diabetes, main countermeasure is that the blood of patient is continually detected with blood glucose meter
Glucose（That is blood glucose）Content, the glucose metabolism in patient is regulated and controled accordingly.
Blood glucose meter major part operation principle is all electrochemical method at present, and enzyme and glucose in blood produce instantaneous when reacting
Electronics is captured by electron mediator, and electric current is electronically formed under voltage effect, and blood glucose meter detection electric current simultaneously converts the current into
The concentration of Blood Glucose shows that therefore, the degree of accuracy of blood glucose meter test result is heavily dependent on blood sugar test paper
Electrode material above.
Crowd's cholesterol levels generally raise, because
This will pay attention to the preventing and treating of high cholesterol.Recently the Asia-Pacific angiocarpy cohort study announced shows, Asia cardiovascular disease incidence rate
Rapid development, and will focus on from now in teenager and urban population.It is expected that the probability that Chinese a middle-aged person suffers from a heart complaint will
Maintain an equal level with the U.S., China will welcome that cerebral apoplexy is high, zooming second of angiocardiopathy peak of myocardial infarction.Courage
The normal value of sterol is 0-5.2mmo/L (0-200mg/dl), is exactly to show as cholesterol height more than this value, cholesterol is high
Harm mainly has：The speed of growth of prostate cancer can be accelerated, the kidney trouble of kidney failure lipid can be triggered；The longevity of people can be reduced
Life, the especially life-span of male apoplexy probability simultaneously relevant with blood vessel can be with increases；Understand clogged heart arteries and make its change
It is narrow, it is easier to trigger heart disease；It can uprise the possibility of osteoporosis, while excessive intake cholesterol can cause periodontal
Ditch gap between disease, tooth and tooth gap can expand.As can be seen here, the high patient of cholesterol will arrive hospital in time and be treated, in order to avoid
Delay treatment, causes that sb.'s illness took a turn for the worse.
The assay method of T-CHOL can be divided into chemical reagent colorimetric method, enzyme assay, fluorescence at present more than 200 kinds
The major class of method, gas phase and high performance liquid chromatography etc. five.The current most widely used method for most easily detecting internal cholesterol concentration
It is domestic portable vitro detection cholesterol instrument, mixes matching test paper, operation principle is similar to blood glucose meter, in test paper
Upper immobilized enzyme and electron transfer mediator, the cholesterol concentration in blood sample is detected by electron transmission.
, it is necessary to provide certain voltage to test paper, induced enzyme and glucose and cholesterol are anti-when measuring blood glucose or cholesterol
The free electric current that electronically forms, blood glucose meter and cholesterol instrument should be produced to be converted according to blood glucose value and the complicated of cholesterol and current value
Relation shows corresponding concentration.
What nowadays market occurred mainly has two class electrodes, carbon electrode and metal electrode.Carbon electrode is mainly using printing
Mode is made, and the method is that graphite and a kind of elargol mixture are mixed, and is coated to surface of plastic matrix, forms electrode.
Current most blood sugar test paper and cholesterol test paper is all to use graphite electrode as working electrode, but graphite electrode makes
During, it can easily be come off and be corroded by external environment influence, and when detecting blood glucose or cholesterol, carbon electricity
Pole transmission speed is low, and caused current signal is slow, reaction time length so that and there is error in test result, test result is inaccurate,
Influence patient and accurately grasp the health status of oneself, so as to easily delay golden hour.Therefore, increasing researcher opens
Begin electrode of the research using metal as conductive media, and metal electrode is mainly with gold, palladium, silver for material.What application was most at present is to adopt
The method of electricity consumption chemical vacuum sputtering prepares metal electrode；Because metal material itself is expensive, and use the method easy
Cause the waste of material so that making material cost is higher, and the equipment price of chemical sputtering is expensive, and operating the equipment also needs
Certain technical foundation is wanted, therefore this method also is difficult to obtain promoting the use of for large area.
Therefore, in order to solve the above problems, there is provided a kind of preparation method of metal electrode.
