Summary
Poly(3-hydroxybutyrate) is a bacterially produced polyester, biodegradable but stiff; type I collagen is the protein cells actually recognise. Blending them at ratios of 100/0, 70/30 and 50/50 and electrospinning the result gives nonwoven mats whose morphological, thermal, mechanical and degradation properties all shift with the ratio. The blend ratio therefore becomes a single dial controlling several properties at once - useful when a scaffold must match a specific tissue.

The mats were produced on a Linari Engineering system (Italy) with a 15 ml glass syringe connected to a stainless steel blunt needle - glass being the usual choice when the solvent would attack a plastic barrel. See our range of systems.
