Optofluidic generation of color and shape encoded microparticle for multiplexed bioassay

We present a new method for in-situ synthesis of multiple color and shape encoded particles in microfluidic channel using single material. Material developed in this work is M-Ink whose color is magnetically tunable and lithographically fixable. By combining novel material system and special instrumentation enables generation of limitless number of codes and greatly simplify the manufacturing process of encoded particles.
