Electric field assisted microfluidic platform for generation of tailorable porous microbeads as cell carriers for tissue engineering
Injection of cell-laden scaffolds in the form of mesoscopic particles directly to the site of treatment is one of the most promising approaches to tissue regeneration. Here, we present a novel and highly efficient method for preparation of porous microbeads of tailorable dimensions (in the range ~ 300-1500 mm) and with a uniform and fully interconnected internal porous texture. The method starts with generation of a monodisperse oil-in-water emulsion inside a flow-focusing microfluidic device.
