The Design And Development Of Spary Membranes System For Colloidal Gold

The immune chromatography test paper is developed in the context of colloidal goldimmune chromatography technology,because of its convenient and needs no specialequipment,and the results can intuitive judgment. In recent years,it attracts more and morepeople’s attention.It developed so rapid that has a wide range of applications in biomedical areaespecially in medical test and it is a new In-vitro Diagnostic Device.However, in the productionprocess of colloidal gold chromatography test paper, the spray colloidal gold operation isbackward,it makes the precision and efficiency is low, and it will impact on the analysis of testresults. This subject introduces a research and development for a kind of spray membranessystem for colloidal gold.The spray membranes instrument involved in the paper meets the spray technologicalrequirements of the gold,and design a special instrument to realize the spray colloidal goldoperation.This article introduces the design principles of the instrument, we choose AT89C52microcomputer chip as the main control chip for data processing and controlling,driving otherperipheral equipments, and also design the PCB circuit board and software program, Realizedthe accuracy and evenness of spray gold every time. The spray membranes instrument has a highreliability, meets the user to realize the spray for operation of gold. The instrument solves theproblem of there is no special of instrument to spray gold at the present. According to thepractical application requirements,design a general structure of the system.Using modular designmethod to design the instrument, and according to different functions of hardware part to designcircuits, then do the circuit tests and experiments for every part; the software design part isblock in to different part,after compiling and debugging every part, combined them together foroverall to debug.In the end to test and improve the whole system.Practice proves,the performances of instrument is simple and easy to operate,the instrumentrealizes the quantitative,uniformly, accurate, automatic spray gold operation on colloidal goldimmune chromatography test paper.Its stable and the accuracy is reliable. It can be applied to theresearch and development of lateral-flow,and be used to reciprocating solution spray gold forproduction customer.
