Abstract The present study reports on the comprehensive physico-mechanical evaluation of 3D printable alginate-methylcellulose hydrogels with bioactive components (Manuka honey, aloe vera gel, eucalyptus essential oil) using a combined experimental-numerical approach. The 3D printable carbohydrate inks demonstrated good swelling properties under moist conditions and adequate antimicrobial and antibiofilm efficacy against both Gram positive and negative bacteria. The effect of the bioactive compo...

Abstract The magnetic field (MF) induced alignment of cellulose nanocrystals (CNC) within a starch matrix is investigated and its effect on the physicochemical and mechanical properties of the nanocomposites are discussed in the paper. Two different kinds of CNC i.e. plant-CNC and tunicate-CNC and its hybrid combination are studied to understand the effect of aspect ratio of CNC on the properties of nanocomposite. Nanocomposites with tunicate sourced CNC showed higher tensile strength and modulu...

Abstract Natural polymeric hydrogel featuring multifunctional properties is more attractive as wound dressing. Herein, Tannic acid (TA)-reinforced methacrylated chitosan (CSMA)/methacrylated silk fibroin (SFMA) hydrogels were fabricated by two-step method of photopolymerization and TA solution incubating treatment. The TA in hydrogels not only served as second crosslinker improving the mechanical performance of up to a 5-fold increase (5 % TA treatment) than the pristine one, but also as functio...

Abstract Cationic and thermo-responsive polymer brushes were grafted from the surface of cellulose nanocrystals. Di(ethylene glycol) methyl ether methacrylate (MEO2MA) and poly(oligoethylene glycol) methyl ether acrylate (OEGMA300) and (2-methacryloyloxyethyl) trimethylammonium chloride (DMC) were grafted from cellulose nanocrystals (CNCs) via free radical polymerization. The CNC-g-POEGMA (CP) possessed a tunable lower critical solution temperature (LCST) of about 50 °C, and cloud point measurem...

Abstract Low molecular weight heparin (LMWH) is reported to have therapeutic action on ulcerative colitis (UC). To facilitate its oral administration and improve the colon-targeting property, LMWH-loaded nanoparticles (TMC-NPs and SA-TMC-NPs) are prepared and evaluated by a series of studies, including their stabilities, drug release profiles, mucosal permeation, mucoadhesion, cytotoxicities, cellular uptake profiles, anticoagulant and anti-inflammatory activities, mucosal healing properties, bi...

Abstract A smart hydrogel with pH/magnetic dual sensitivity was synthesized by in-situ synthesis of Fe3O4 inside carboxymethyl chitin hydrogel matrix prepared from Hericium erinaceus residue. The structure, pH/magnetic sensitivity, swelling and drug release behavior of the prepared hydrogels were investigated. The results showed that Fe3O4 nanoparticles were successfully synthesized and uniformly distributed within the hydrogels. The prepared hydrogels could be attracted by the magnet and exhibi...

Abstract We fabricate transparent cellulose nanopapers with significantly enhanced flame retardancy by a vacuum filtration assisted layer-by-layer deposition method. Flame retardancy is enhanced by increasing the layer-by-layer thickness while not hampering optical transparency of the nanopapers. Thermal degradation and combustion behaviors show that the nanopapers have been successfully functionalized by phosphorus and amine compounds that act effectively as intumescent and blowing agents. Base...

Abstract The present study reports the successful synthesis of the flame-retardant and smoke-suppressant flexible polyurethane foam (FPUF) through the use of a fully bio-based coating. Hydroxyapatite (HAP) is added to the solutions containing sodium alginate (SA) and chitosan (CH), respectively, to create negative and positive charges for Layer-by-Layer (LbL) assembly. The influence of the solution concentrations and bilayers numbers deposited on the flame-retardant and mechanical properties of ...

Abstract Conventional isolation of chitin from crustacean waste demands the use of high amounts of hazardous chemicals, hence not leading to a sustainable process. Atmospheric-pressure dielectric barrier discharge (DBD) plasma has demonstrated an enhanced ability to remove proteins directly from the biomass without the formation of any waste. Simultaneously, organic acids have proven very efficient in the removal of inorganic minerals from crustacean waste. Therefore, a hybrid process composed o...

Abstract At present, diabetes and diabetic complications have become one of the serious diseases affecting human health. In this study, the inhibitory effects of Lentinus edodes mycelia polysaccharide (LMP) on α-glucosidase activity, the formation of advanced glycation end products (AGEs) and high glucose-induced human umbilical vein endothelial cells (HUVECs) damage were explored. The interaction between LMP and α-glucosidase and the inhibition against AGEs formation were investigated with spec...
