PVA-sodium alginate (SA) hydrogel membranes containing sodium ampicillin as a topical antibiotic were developed using the freeze–thawing method for wound dressing application. Aqueous solution of has been blended in certain ratio with PVA, followed by crosslinking conducted physical instead use traditional chemical to avoid riskiness reagents and crosslinkers. The physicochemical properties PVA-SA e.g. gel fraction water uptake % have performed. Increased SA content PVA decreased fraction,...
Poly(vinyl alcohol), PVA is a polymer of great importance because its many appealing characteristics specifically for various pharmaceutical and biomedical applications. Physically crosslinked hydrogel membranes composed different amounts hydroxyethyl starch (HES) in (PVA) ampicillin were prepared by applying freeze–thawing method. This freezing–thawing cycle was repeated three consecutive cycles. Physicochemical properties PVA–HES membrane gel such as fraction, swelling, morphology,...
The rapid advancements in nanotechnology the field of nanomedicine have potential to significantly enhance therapeutic strategies for cancer treatment. There is considerable promise enhancing efficacy therapy through manufacture innovative nanocomposite materials. Metallic nanoparticles been found release anticancer medications that are loaded onto them, resulting a sustained release, hence reducing dosage required drug administration and preventing their buildup healthy cells. combination...
Abstract This study aims to prepare novel cross-linked antimicrobial membranes composed of PVA-Aloe vera hydrogels using physically method via transforming PVA high crystalline structure propanol. Curcumin was incorporated improve the membrane biological properties; while gentamycin improved sharply properties. hydrogel were analyzed by FTIR, SEM, XRD and TGA measurements for characterizing resultant membranes. Physicochemical measurements, e.g., swelling mechanical stability assessed...
The present study aimed at preparing novel free-radical scavenging and water-soluble compounds derived from gelatin. Specifically, gelatin−syringaldehyde, gelatin−anisaldehyde, gelatin−vanillin were synthesized thoroughly studied for their physicochemical properties. In particular, the characterized by UV-Vis spectroscopy, Fourier-transform infrared scanning electron microscopy. Notably, as demonstrated thermogravimetry differential calorimetry, all three derivatives exhibited higher thermal...
Abstract Novel physically-crosslinked PVA membranes blended with Aloe vera extract were fabricated by solution-casting method. Physically-crosslinking process is depending on the rearrangement of chains forming intermolecular hydrogen bonding removal water molecules using propanol as a stabilizing agent. The structure crosslinked was characterized FT-IR, SEM, TGA, and XRD analyses confirmed via gel faction swelling ratio studies. Caffeine vitamin C loaded-PVA/Aloe bio-assessed in terms their...
Wound dressings are highly desired for the treatment of chronic wound infections. This study aimed to prepare membranes composed chemically crosslinkedPVA and Gelatin polymers. Curcumin was added improve membrane's biological properties. FTIR spectroscopy used investigate their chemical structures, while SEM TGA analysis were applied studies morphology membrane thermal properties crosslinked membranes. In addition, contact angle measurement also performed get more information about...
