2010 Latest R&D on PHAs

Fabrication of scaffolds from PHB and PHBV for tissue engineering

produce only thin films or 3-D scaffolds less than 2 mm → NONE of

the studies produced 3-D scaffolds more than 2 mm in thickness.

The usage of variety of PHB and PHBV concentration from 1% to

5% (w/v) in chloroform → but still producing only thin films →

Why this study was conducted?

5% (w/v) in chloroform → but still producing only thin films →

NONE of the studies identified the ideal concentration for

fabricating 3-D scaffolds.

Problems of using SCPL techniques → residual of porogen →

efficacy of SCPL and the effect on the cell growth media.
