The revolution in the basic science of molecular cell biology, combined wit
h advances in polymer science and engineering, is pushing the field of biom
aterials into new applications and an era of molecular design. New classes
of degradable polymers and hydrogels are bring developed and teamed with mo
lecular ligands to control specific cell behaviors. This paper reviews the
basic science and technology for applications in drug delivery and tissue e
ngineering. (C) 2000 Published by Elsevier Scientific Ltd on behalf of Acta
