Polyvinylpyrrolidone (PVP) is a synthetic polymer that holds significance in various fields such as biomedical, medical, and electronics, due to its biocompatibility exceptional dielectric properties. Electrospinning the most commonly used tool fabricate fibers because of convenience wide choice parameter optimization. Various parameters, including solution molarity, flow rate, voltage, needle gauge, needle-to-collector distance, can be optimized obtain desired morphology fibers. Although PVP commercially available molecular weights, with weight 130,000 g/mol generally considered easiest minimal challenges. However, fiber diameter this case usually micron regime, which limits utilization require diameters nano regime. Generally, lower weight, 10,000 55,000 g/mol, known present challenges preparation. In current study, optimization for possessing weights was carried out nanofibers. The electrospinning technique utilized fabrication by optimizing above-mentioned parameters. SEM analysis performed analyze morphology, quantitative correlate effect parameters on morphology. This research study will lead applications, drug encapsulation sustained release nanoparticles/nanotubes microwave absorption applications.

Abstract Buspirone hydrochloride (BSP) is an anxiolytic agent approved for the management of anxiety disorders. The current US-FDA medications BSP are administered via oral route, which linked to several disadvantages such as low bioavailability and half-life necessitating multiple daily doses. For chronic diseases disorders, where long-term or lifelong often required, these factors impact patient compliance treatment adherence. present study offers alternative approach by investigating feasibility sustained transdermal delivery long-acting microneedles (MNs).

A nanoparticle-free, bioabsorbable pol-yvinyl alcohol (PVA) with citric acid (CA) dressing produced by simple electrospin-ning was evaluated to treat acute in rats. This PVA-CA combination promotes crosslinking, increases the capacity absorption and confers heal-ing properties due antioxidant action. tested a quantitative experiment on 1.9 cm dermatological lesions rats (n = 12), com-paring PVA-CA-treated group untreated control (CG). Samples were collected at 3, 7 14 days after lesion induction evaluate inflammatory tissue healing. macroscopic histological data third day showed similar characteristics both groups; however, fourteen days, exhibited complete healing, accompanied recomposition skin layers, whereas wounds CG did not close completely. results highlight that electrospun PVA-AC dressings improve outcomes constitute prom-ising affordable solution, providing suitable environment repair, re-ducing cell infiltration, blood vessel formation, restoration epi-thelial tissue, reducing time wounds.
