Biodegradable microfluidics

A biodegradable microfabrication platform for constructing 3D high-resolution devices for tissue engineering and drug delivery is presented. Biodegradable polymer films with built-in micrometer-scale features are stacked and fusion bonded to construct fully biodegradable, poly(DL-lactic-co-glycolide) (PLGA)-based, monolithic, multilayer, microfluidic networks. Integration with cells or drug compounds will enable use of these devices in therapeutic applications (scale bar: similar to 300 mum).
