Allgemeine Beschreibung

Characteristic properties of ester terminated poly(D,L-lactide-co-glycolide) (PLGA) are in vivo biodegradability, tunable drug release profile and very high encapsulation capacity.

Anwendung

PLGA polymers find uses in the production of biodegradable medical sutures and for controlled drug release. PLGA microspheres have been reported for use in controlled release of human growth hormone. Thin membranes of blended polymers constituting of PLGA/polycaprolactone/β-tricalcium phosphate have been used in guided bone regeneration.

Anisotropically compartmentalized microparticles have attracted increasing interest in areas ranging from sensing, drug delivery, and catalysis to microactuators. Herein, a facile method is reported for the preparation of helically decorated microbuilding blocks, using a modified electrohydrodynamic cojetting method. Bicompartmental microfibers
