This paper presents a novel microfluidic chip that can achieve gas-liquid segment flow, plasma discharge, gas-liquid separation, liquid collect and mercury ion detection. Instead of using conventional chemical reaction method, this chip uses helium plasma as the reducing agent to reduce gold ion and synthesize gold nanoparticle (AuNP), such that there is no residual reducing agent in the solution after removing the electric field for plasma generation. The synthesized gold nanoparticles are… CONTINUE READING
