Optimization of Ultraviolet Ozone Treatment Process for Improvement of Polycaprolactone (PCL) Microcarrier Performance

Growing cells on microcarriers may have overcome the limitation of conventional cell culture system. However, the surface functionality of certain polymeric microcarriers for effective cell attachment and growth remains a challenge. Polycaprolactone (PCL), a biodegradable polymer has received consid...
