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,...
Hemorrhage is the major hindrance over wound healing, which triggers microbial infections and might provoke traumatic death. Herein, new hemostatic antibacterial PVA/Kaolin composite sponges were crosslinked using a freeze-thawing approach boosted by penicillin-streptomycin (Pen-Strep). Physicochemical characteristics of developed membranes analyzed adopting Fourier transformed infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermal gravimetric analyzer (TGA), differential...
Abstract Green-based materials represent a new promising class of ecofriendly and economic adsorbents. Herein, nano zero-valent iron supported-lemon derived biochar (NZVI-LBC) was prepared for the first time examined in adsorptive removal methylene blue as model pollutant. Different characterization tools were used to ensure successful fabrication NZVI-LBC composite including FTIR, XRD, TEM, XPS, VSM, BET, zeta potential analysis. It found that fabricated NZVI–supported attained propitious...
Water pollution is a dreadful affair that has incessantly aggravated, exposing our planet to danger. In particular, the persistent nitro aromatic compound like nitrophenols causes anxiety researchers due their hazardous impacts, excessive usage, and removal difficulty. For this purpose, novel multi-featured composite was constructed based on κ-Carrageenan (κ-Carr), MOF (MIL-125(Ti)), magnetic Fe
Abstract The present study introduces a new and straightforward method for the amination of Chitosan. This involves coupling Chitosan (CS) with 2-chloroethylamine (ENH2) in single step to produce an amino-ethyl derivatives increased amine group content (CS-ENH2) using click chemistry. resulting were then crosslinked Glutaraldehyde form Schiff bases. novel bases subsequently utilized as adsorbents removal Methyl Orange (MO) dye from aqueous solutions batch technique, performance produced was...
Two self-associating biopolymers, namely chitosan (Ch) and a high-molar-mass hyaluronan (HA), were used to prepare membranes with the aim protect enhance healing of injured skin. A mitochondrially-targeted antioxidant—MitoQ—was incorporated into mixture biopolymers prior their self-association. These three-component evaluated in detail utilising surface roughness measurements, contact angle hemocompatibility, thrombogenicity analyses. Furthermore, vivo application Ch/HA/MitoQ was assessed on...

An effective drug nanocarrier was developed on the basis of a quaternized aminated chitosan (Q-AmCs) derivative for efficient encapsulation and slow release curcumin (Cur)-drug. A simple ionic gelation method conducted to formulate Q-AmCs nanoparticles (NPs), using different ratios sodium tripolyphosphate (TPP) as an crosslinker. Various characterization tools were employed investigate structure, surface morphology, thermal properties formulated nanoparticles. The NPs displayed smaller...
Abstract Utilizing Glutaraldehyde crosslinked sodium carboxymethyl cellulose (CMC-GA) hydrogel and its nanographene oxide composite (CMC-GA-GOx), an effective cellulose-graphene biobased composites adsorbent was developed for the adsorption removal of methylene blue (MB) cationic dye contaminate from industrial wastewater. The CMC-GA-GOx were characterized using FTIR, RAMAN, TGA, SEM, EDX analysis instruments. Through batch experiments, several variables affecting MB dye, including...
In this study, a novel ampholyte hydrogel known as amino-ethyl carboxymethyl cellulose crosslinked (AECMC) was synthesized and utilized to remove Methyl orange (MO), an azo-dye commonly found in dyes contaminated wastewater.
