Microfluidic chip with multiple functions for sensing
Microfluidics are widely used in many applications from cell sorting, cell lysis or even molecular detection purposes. In this study, polymethyl(methacrylate) (PMMA) is the material used for the fabrication of the microfluidic chip. The design of the microfluidic chip involves integrating the mixing...
