Polyhydroxyoctanoate films reinforced with titanium dioxide microfibers for biomedical application

Biological and physiochemical studies of electrospun polylactid/polyhydroxyoctanoate PLA/P(3HO) scaffolds for tissue engineering applications

“…The most uniform bers, with the narrowest size distribution and smallest ber diameter, were in 50PLA-50PHO sample. Viscosity of the 50PLA-50PHO electrospinning solution was in the optimal range, however, slow crystallization of PHO, 23 which was present in substantial amount, caused fusions at multiple contact, crossing points between adjacent layers of semi-solidied bers. If the polymer crystallizes slowly, bers are not fully solidied upon deposition which leads to welding or fusion at contact, crossing points.…”

Polyhydroxyalkanoate/Antifungal Polyene Formulations with Monomeric Hydroxyalkanoic Acids for Improved Antifungal Efficiency

“…The presence of antimicrobial and bioactive bio-glass made films suitable for tissue engineering and wound dressing. The impregnation of mcl-PHA films with bioactive, inorganic constituents (e.g., hydroxyapatite [ 68 ] and titanium dioxide [ 69 ]) has also improved their mechanical properties and bioactivity, potentially leading to osteoinductive scaffolds. Porous and neat PHO films, designed by Bagdadi et al as cardiac patches, supported viability, adhesion and contraction of neonatal ventricular rat myocytes [ 15 ].…”

Gaining control of bacterial cellulose colonization by polyhydroxyalkanoate-producing microorganisms to develop bioplasticized ultrathin films

“…The presence of PHA in the fabricated materials was demonstrated by the bands at 1724 cm − 1 in the FTIR analysis (Fig. 4a), which was assigned to the stretching vibration of the amorphous carbonyl group, and those bands at 2924 and 2956 cm − 1 , corresponding to the CH asymmetric stretching vibration of aliphatic CH 2 and CH 3 , respectively [31].…”
