Pore-fect Delivery

A scanning electron micrograph of porous PLGA – poly(lactic-co-glycolic acid) – microparticles. One potential application for these biodegradable and biocompatible particles is as a carrier for delivering mesenchymal stem cells for in vivo regenerative medicine. One of the particles has been damaged during the leaching process (where the pores are created) and has ended up with smaller particles enclosed within it. The image was taken at the Nanoscale and Microscale Research Centre at the University of Nottingham.
