Preparation of Magnetic Porous Microspheres and Their Ability to Remove Oils

open access: yesMacromolecular Materials and Engineering, 2020
Magnetic, porous poly (tripropylene glycol diacrylate) (PTPGDA) microspheres are successfully prepared using a combination of microfluidic emulsification and free‐radical polymerization. The porous structure can be precisely controlled by controlling the

Controlled release properties and final macroporosity of a pectin microspheres–calcium phosphate composite bone cement [PDF]

open access: yes, 2010
The use of calcium phosphate cements (CPC) is restricted by their lack of macroporosity and poor drug release properties. To overcome these two limitations, incorporating degradable polymer microparticles into CPC is an attractive option, as polymer ...

CaSiO3 microstructure modulating the in vitro and in vivo bioactivity of poly(lactide-co-glycolide) microspheres [PDF]

open access: yes, 2011
Poly (lactide-co-glycolide) (PLGA) microspheres have been used for regenerative medicine due to their ability for drug delivery and generally good biocompatibility, but they lack adequate bioactivity for bone repair application.
