Modification of protein crystal packing by systematic mutations of surface residues: implications on biotemplating and crystal porosity.

13 Oct 2009 Bioinspired nano-scale biotemplating for the development of novel composite materials has recently culminated in several demonstrations of nano-structured hybrid materials. Protein crystals, routinely prepared for the elucidation of protein 3D ... Read more...

Tissue-engineered polyethylene oxide/chitosan scaffolds as potential substitutes for articular cartilage.

29 Sep 2009 Applications of composite scaffolds comprising polyethylene oxide (PEO) and chitosan to the culture of bovine knee chondrocytes (BKC) were investigated. Here, PEO and chitosan with various weight ratios were crosslinked, refrigerated at -80 degrees ... Read more...

Smooth muscle cell adhesion in surface-modified three-dimensional copolymer scaffolds prepared from co-continuous blends.

29 Sep 2009 In this article, tissue-engineering scaffolds were fabricated from P(epsilon-CL-co-D,L-LA)-PEG-P(epsilon-CL-co-D,L-LA) copolymers using co-continuous blends with polystyrene as the porogen phase. By means of static annealing and following extraction ... Read more...
