Fabrication method of Dopamin sensor based on platinum nanoparticle-decorated carboxylated polypyrrole nanoparticles

摘要

The present invention relates to a method for producing a very fine carboxylated polypyrrole nanoparticle-based dopamine sensor with platinum particles, wherein the carboxylated polypyrrole nanoparticles into which the functional group has been introduced are dispersed in distilled water and mixed with an aqueous solution of platinum tetrachloride Preparation of ultra sensitive carboxylated polypyrrole nanoparticles with platinum particles using a reducing agent and ultrasonic treatment followed by uniformly arraying and fixing them on the sensor electrode using spin coating / RTI According to the present invention, there is an advantage that a sensor capable of detecting dopamine without the help of enzymes can be manufactured by a simple manufacturing method without a pretreatment process. Further, the dopamine sensor which can be produced according to the present invention has an advantage of being highly sensitive to detect a very small amount of dopamine, and having excellent reusability in which performance is maintained even for a number of times of reuse.
