Innovative spiral nerve conduits: Addressing nutrient transport and cellular activity for critical-sized nerve defects

Bioactive Materials
Large-gap nerve defects require nerve guide conduits (NGCs) for complete regeneration and muscle innervation. Many NGCs have been developed using various scaffold designs and tissue engineering strategies to promote axon regeneration.

In vitro and transdermal penetration of PHBV micro/nanoparticles

Journal of Materials Science: Materials in Medicine, 2014
The purpose of this study was to develop micro and nano sized drug carriers from poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), and study the cell and skin penetration of these particles. PHBV micro/nanospheres were prepared by o/w emulsion method and were stained with a fluorescent dye, Nile Red. The particles were fractionated by centrifugation

Dynamic mechanical properties of PLA/PHBV, PLA/PCL, PHBV/PCL blends and their nanocomposites with TiO2 as nanofiller

Thermochimica Acta, 2015
Abstract The effect of blending and the addition of small amounts of TiO2 nanoparticles on the dynamic mechanical properties of PLA/PHBV, PLA/PCL and PHBV/PCL blends is reported in this paper. The storage modulus of the PLA/PHBV blends was higher than those of both PLA and PHBV in the temperature region below the glass transition of PHBV, but the PLA/
