Surface functionalized PLLA for scaffold preparation
Biocompatible and degradable poly(alpha-hydroxy acids) are among the more widely used materials in scaffolds for tissue engineering, although they often need surface modification to improve their interaction with the cells. In the present research Poly(L-lactide) 3D scaffold were prepared by salt-leaching method, with a porosity of 80 % and interconnected pores. In order to increase the hydrophilicity of the PLLA scaffolds surface, taurine was grafted through aminolysis reaction.
