Introduction

Qiaosheng Pu’s research interests are mainly on microfluidic biosensors, miniaturized analytical devices and their application. His group has developed simple fabrication procedures for low-cost and disposable microfluidic chips, built a series of low-cost miniaturized devices for microchip electrophoresis, established convenient ways for the characterization of microchannel surfaces. The group is developing easy-to-use and portable microchip electrophoresis devices and robust protocols that can be used outside the professional laboratories. Plenty of efforts have been put on laser-induced fluorescence detectors and capacitively coupled contactless conductivity detectors to make them smaller, cheaper and better in performance. Along with these subjects, they also work on the microfluidic analysis using smartphones as a detection tool and the synthesis of novel fluorescent nanomaterials and porous carbon based materials.
