Traditional hydrogels have shown substandard multifunctional, mechanical properties in biomedical field. Gold nanoparticles can provided an expanded array of nanostructured materials with exclusive biomedical properties. The nanocomposite hydrogels have expected to exhibit both nanomaterial and hydrogel properties, which may resulted in potential applications in biomedical field. Hence, the present investigation reported simple and greener approach to the preparation and properties of pH-responsive nanocomposite hydrogels (GIAE) based on itaconic acid (IA), acrylic acid, ethylene glycol and colloidal gold nanoparticles. The obtained nanocomposite hydrogels found to have desired exfoliated surface morphology and enhanced pH-sensitive swelling and thermal stability. It also showed appreciable anti-microbial properties due to presence of gold nanoparticles and IA. The cytotoxicity nature of itaconic acid based gold nanocomposite hydrogels were also developed ~ 90% due gold nanoparticles. Moreover, the degradation property of prepared nanocomposite hydrogels have been reduced due to bacterial inhibition tendency of gold nanoparticles. This work provides viewpoints to develop pH-tunable GIAE nanocomposite hydrogels with significant biological properties. The resultant nanocomposite hydrogels may be recommended for biomedical applications mere in future such as pH-sensitive drug delivery, scaffold for tissue engineering, wound healing application, antimicrobial material and nanomedicine etc.

“…Just like conventional supramolecular hydrogels, supramolecular hydrogel-based DESs will certainly attract significant interest for their possible use in interesting applications, such as hygienic products, drug delivery systems, biomedical applications, sensors and pharmaceuticals, the removal of dyes and metal ions and sewage water treatment, and the purification of water, among others. [24][25][26][27] The rheological properties of the hydrogels were also obtained by investigating the viscometry in rotational mode and viscoelastic properties in oscillation mode, as well as by thixotropy and creep/recovery tests. A rotational rheometer from Malvern (Kinexus pro) was used with a cone-and-plate geometry.…”

“…This occurs due to the interaction between hydrophilic group (OH -) of HEMA and the water molecules, which generates hydrogen bonds that allow its absorption and produce swelling [12,13]. On the other hand, in literature it has been described that crosslinked polymers that are composed of acrylic acid (AA) monomers [14,15], N-vinylpyrrolidone (NVP) [16,17], and itaconic acid (IA) [18,19], also possess a high hydration capacity due to the functional groups that have in its molecular structure, generating proper hydrophilicity. Among the structural features of these materials predominate its superficial properties, permselectivity and permeability, which gives hydrogels its unique and interesting properties [20,21].…”

In the present work, three hydrogels of poly(2-hydroxyethyl methacrylate-co-itaconic acid), p(HEMA-co-IA), poly(2-hydroxyethyl methacrylate-co-acrylic acid), p(HEMA-co-AA) and poly(2-hydroxyethyl methacrylate-co-(1-vinyl-2-pyrrolidone)), p(HEMA-co-NVP) were prepared by free radical polymerization in aqueous solution (1:1 monomer mole ratio) using ammonium persulfate as initiator and N,N´-methylenebisacrylamide as crosslinking agent at two different amount (0.3 and 0.9 mol%). The obtained hydrogels were characterized by Fourier transform infrared spectroscopy (FT-IR), which allowed to verify the structural composition. Thermal analysis of the hydrogels was carried out by thermogravimetric analysis (TGA). In addition, hydration capacity (U%) was studied at different experimental conditions such as: time, pH, concentrations of interfering salts (KCl, NaCl and LiCl). The results showed a good polymerization yield (95%). FTIR characterization shows the absorption bands of the functional groups of copolymers. TGA exhibited the characteristic thermal stability of this type of hydrogels. The presence of comonomer AI, AA or NVP in copolymer determine the thermal behavior. Hydration experiments revealed a higher U% in copolymer containing more carboxylic acid groups. The maximum U% values in water were 400% and 250% for p(HEMA-co-AI) and p(HEMA-co-AA), respectively. For P(HEMA-co-NVP) a maximum of U% value was only 74% in water. The effect of interferent salts affects the hydration capacity decreasing U% when the concentration of salts increase.
