By using the device, small molecules can be quickly and intuitively detected, and meanwhile, the device is low in price of raw materials, and simple in preparation method, and the raw materials are easy to obtain.
Description
Technical field
The utility model belongs to a kind of pick-up unit, is specifically related to a kind of Liquid Crystal Sensor pick-up unit.
Background technology
The sensing technology changing based on liquid crystal aligning is an emerging biological chemistry detection technique.This technology is to utilize sensor to detect before and after target compound, liquid crystal molecule changes in the orientation on sensitive membrane surface, the ability that changes liquid crystal refracted ray, causes the color of sensor and luminance brightness to change, thereby realizes the detection to biomolecule, harmful chemical.
The research of this sensor changing based on liquid crystal aligning is to have high scientific research value and realistic meaning.Be expected to be developed to a kind of brand-new, with the natural lights such as daylight do light source, visual detection, without power supply, can carry out the microsensor of high sensitivity, high resolving power, field quick detection.But in current research work, related test substance kind is limited to very much, a class is organic amine, organophosphorus gas molecule, and an other class is bioactive macromolecule.And the detection of the little molecule of the poisonous and harmful in some aqueous solution or biological micromolecule be have not been reported, if can realize the detection to these molecules, bring larger value can to undoubtedly the research of Liquid Crystal Sensor.
Utility model content
The purpose of this utility model is to provide a kind of Liquid Crystal Sensor pick-up unit, uses this device energy quicklook little molecule is detected, simultaneously this device make raw material inexpensive, be easy to get, preparation method is simple.
For achieving the above object, technical solution adopted in the utility model is:
This device comprises wave carrier piece, it is the pellosil of 0.8～1.5 millimeter that wave carrier piece is provided with thickness, has multiple square silica gel fenestras on pellosil, and silica gel fenestra is provided with the circular copper mesh that is slightly less than silica gel fenestra, the thickness of circular copper mesh is 0.02 ~ 0.06 millimeter, and sizing grid is 70 ~ 150 orders.
Preferably, the width of silica gel fenestra is 3～6 millimeters, and the diameter of copper mesh is 2～5 millimeters.
Preferably, wave carrier piece thickness is 1 ~ 3 mm, and length is 1 ~ 5 centimetre, and width is 1 ~ 2 centimetre.
The beneficial effect that this Liquid Crystal Sensor pick-up unit produces is: use this device can quicklook little molecule is detected, the raw material of this device making is simultaneously inexpensive, be easy to get, and preparation method is simple.
Brief description of the drawings

The method for making of Liquid Crystal Sensor pick-up unit is as follows:
1) with tweezers, the copper mesh 4 that scribbles liquid crystal is clipped and left standstill more than 5 minutes;
2) pellosil 2 is cut into a square that is slightly less than microslide, and makes a call to a circular hole that is slightly larger than copper mesh diameter at center membrane;
3) pellosil having openning hole 2 is affixed on microslide 1, the edge of silica gel fenestra 3 can not rub with copper mesh 4;
4) solution preparing is added in silica gel fenestra 3, the copper mesh 4 that scribbles liquid crystal is put into the surface of sample liquid, be placed on the variation of polarized light microscopy Microscopic observation polarisation figure.
Use the detection method of this device as follows:
1) testing sample solution is joined in the silica gel fenestra 3 of Liquid Crystal Sensor;
2) copper mesh 4 that scribbles liquid crystal is put into the surface of sample liquid;
3) judge detection effect in the variation of polarized light microscopy Microscopic observation polarized light image.
Above-mentioned embodiment is used for the utility model of explaining; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment and change that the utility model is made, all fall into protection domain of the present utility model.
