Biomedical implants possessing the structural and functional characteristics of extracellular matrix (ECM) are pivotal for vascular applications. This study investigated the potential of recreating a natural ECM-like structural and functional environment on the surface of biodegradable polymeric nanotextiles for vascular implants. Human adipose-derived mesenchymal stem cells (MSCs) were grown on a suitably engineered polycaprolactone (PCL) nanofibrous textile and were allowed to modify its surface through the deposition of MSC-specific ECM.

Mandible reconstruction and dental rehabilitation after trauma or tumor resection represent a serious challenge for maxillofacial surgeons. This study aimed to investigate the bone formation potential of nanocomposite fibrous scaffold (silica-nanohydroxyapatite-gelatin reinforced with poly L-lactic acid yarns - CSF) for delayed Titanium (Ti) implantation, which was compared to autograft (AG) taken from the iliac crest. The grafts were placed in critical-sized mandibular defects in an adult pig model for 6 months followed by dental implant placement for another 3 months.

The main intent of this investigation was to retain the strength and superabsorbency of natural and non-toxic biodegradable polymers using an innovative combination of cross-linkers for application as the absorbent core of sanitary napkins. For this, sodium carboxymethyl cellulose (NaCMC) and starch were blend to form membranes by phase inversion and lyophilisation, using an optimized cross-linker combination of sodium trimetaphosphate (STMP) and aluminium sulphate (AlS). Optimal cross-linking of NaCMC and starch hampered membrane dissolution and disintegration, yielding a microtextured surface morphology.

In this study, we fabricated a trifunctional polyurethane (PU)/graphene oxide (GO) electrospun membrane for adsorption of organic dyes such as methylene blue (MB) and rhodamine B (RB). Moreover, the prepared membrane showed antifouling property and inhibition against bacteria. The GO modified PU nanofiber shows a maximum adsorption capacity of 109.

pH stimuli drug release nanofibrous membranes of polyurethane/dextran were developed for tailoring of antibacterial wound dressings. Incorporation of dextran in polyurethane (PU) showed increment in hydrophilicity, vapour transmission rate, percentage sorption values, and biodegradability. Dextran also acts as reinforcement filler in PU matrix.
