Abstract

Colloidal gels are fabricated using oppositely charged, biodegradable poly(D,L-lactic-co-glycolic acid) (PLGA) nanoparticles that interact to form stable 3D structures. Malleability under shear and strong static cohesion facilitate the fabrication of shape- specific tissue-engineering scaffolds.
