In can include two or more initiator to different temperatures reaction so that photochromic layer 160 can be in response to
Different ambient temperature and change color.
Significantly, since the activity change speed of conversion zone 140 (can be for example oxidoreductase
Active rate of regression) be equal to photochromic layer 160 concentration change speed (can be for example conjugated polymer
Concentration change speed).Therefore, when the active rate of regression of the oxidoreductase in conversion zone 140 is for
When knowing (can such as by learn in experiment), the concentration change speed of the conjugated polymer in photochromic layer 160
Then can be defined with formula (2) by formula (1), its is as follows:
Wherein
K is the reaction rate constant of the photochromic layer 160, and it is defined by formula (2);
T is the temperature under absolute scale;
A, b are experimental constant, and wherein a is the rate of change constant K and temperature T of photochromic layer 160
Intercept, b is the slopes of the rate of change constant K with temperature T of the photochromic layer 160;
C0For the original concentration of the photochromic layer 160;
CiFor the varied concentration to be presented of the photochromic layer 160, wherein the varied concentration is defined as reaction
Layer 140 loses varied concentration during original measurement function;
A is the reaction rate of conversion zone 140 or photochromic layer 160 at temperature T.
It should be noted that reaction rate constants of the K for photochromic layer 160, it can pass through described common
The concentration of conjugated polymer, monomer, sensitizer and initiator is adjusting.In other words, in the present embodiment,
Photochromic layer 160 can be controlled by the concentration of the conjugated polymer, monomer, sensitizer and initiator
Color change under specified temp and time.
However, the present invention is not intended to limit the color performance and excursion.As long as the discoloration of the present embodiment
The face that layer 160 is presented when losing original measurement function because of environmental factorss (can be for example ambient temperature)
Color is poor at a distance of the colour atla code of more than 1 with the color presented when just completing and producing (or just dispatching from the factory).
In one embodiment, photochromic layer 160 can lose original because of environmental factorss (can be for example ambient temperature)
The color presented during measurement function is presented the colour atla of more than 7 with the color presented when just completing and producing
Code is poor.
" the colour atla code " is " the color wildcard issued according to " Cai Tong companies " (Pantone Inc.)
Colour system is united”(PANTONE MATCHING) in specified color coding.Such as
Using Pantone Yellow 8pts, Pantone Warm Red 0.125pts and Pantone
The allotment achievement of Trans.Wt.56pts is the yellow of color logical color matching system colour atla code PMS 106C, and correlation is retouched
State in the notification number of U.S. Patent No. 5734800, patent name be " Six-color process system " in,
Here is incorporated into using as above-mentioned reference.And the colour atla code difference is " the logical color matching system of coloured silk" in
Coding it is poor, for example, PMS 106C and PMS 105C or PMS 107C are presented 1 colour atla code
Difference.
Fig. 2 is the loss of activity figure of the conversion zone of experimental example 1-2.
< tests >
In order to prove the realizability of the present invention, experimental example will be hereafter lifted with the present invention more particularly described below.
Although describing following experiment, in the case of insurmountability scope, can suitably change used
Material, its amount and ratio, process details and handling process etc..Therefore, should not be according to hereinafter described
Explanation of the experiment to restricting property of the present invention.
(experimental example 1)
In biochemical test piece configuration with conjugated polymer photochromic layer, wherein the biochemical test piece be to
Measure cholesterol.Then, the biochemical test piece is positioned over into temperature in the environment of 30 degree Celsius, continuously
Place 51 days, and observe the color change of photochromic layer.The color change of photochromic layer is as shown in Figure 2.
(experimental example 2)
In biochemical test piece configuration with conjugated polymer photochromic layer, wherein the biochemical test piece be to
Measure cholesterol.Then, the biochemical test piece is positioned over into temperature in the environment of 50 degree Celsius, continuously
Place 51 days, and observe the color change of photochromic layer.The color change of photochromic layer is as shown in Figure 2.
Shown by the result of Fig. 2, compared with experimental example 1, taken the photograph because the biochemical test piece of experimental example 2 is in
At a high temperature of 50 degree of family name, its oxidoreductase activity for being likely to result in experimental example 2 successively decreases, and causes experimental example
2 oxidoreductase loses original activity or forfeiture respond partially or completely.On the other hand,
The electron transfer instrumentality (e.g. potassium ferrocyanide) of experimental example 2 also can light or heat impact and lead
Structure change is caused, and the structure change is mostly irreversible reaction.Therefore, the biochemistry of experimental example 2
The activity of test piece just decreases below 90% (placing 8 days) from 100% (placing 0 day), and it falls into
Outside the allowed band (i.e. 90%) of sensing cholesterol.In other words, after placing 8 days, experimental example
2 biochemical test piece by permanent loss it is original measurement cholesterol function.
In addition, as shown in Fig. 2 the color of the photochromic layer of experimental example 1 from place 0 day to place 51 days all
For same color (PMS 3155C).And the color of the photochromic layer of experimental example 2 is from the color for placing 0 day
(PMS 3155C) changes to the placement color (PMS 2955C) of 21 days, and then changes to placement 51
It color (PMS 288C).Therefore, user is just available is pre-printed the comparison on test piece tank
Color, comparing the color of the photochromic layer of biochemical test piece can learn whether biochemical test piece is damaged.
In sum, the present invention is utilized and is at least configured on the region outside conversion zone and with conjugated polymers
The photochromic layer of thing, its color can change with the change of environmental factorss.And the color change of photochromic layer
Various words, numeral, figure, pattern, symbol etc. can be shown as.Therefore, user need not be by sample
Product are inserted reaction zone and just can learn whether the biochemical test piece is damaged, and it can not only reduce the consume of sample,
The risk of the detection error of biochemical test piece can also be reduced.
Finally it should be noted that:Various embodiments above is only illustrating technical scheme rather than right
Its restriction;Although being described in detail to the present invention with reference to foregoing embodiments, this area it is common
Technical staff should be understood:It still can modify to the technical scheme described in foregoing embodiments,
Either equivalent is carried out to which part or all technical characteristic;And these modifications or replacement, and
The scope of the essence disengaging various embodiments of the present invention technical scheme of appropriate technical solution is not made.
