The microgel network has been constructed via free-radical emulsion polymerization of styrene, N, N-dimethylacrylamide, methacrylic acid, and N-(hydroxymethyl)acrylamide (crosslinker), followed by hydrothermal incorporation of CuO nanoparticles. Comprehensive characterization using FT-IR, TGA, DLS, XRD, EDX, SEM, TEM, and UV–vis spectroscopy has confirmed successful microgel formation, thermal stability up to ~ 340 °C, reduced hydrodynamic size after CuO loading, and uniform nanoparticle distribution within the microgel matrix. The embedded CuO nanoparticles have exhibited a crystalline size of 4.34 nm. Catalytic studies have demonstrated that M@CuO effectively reduced both methylene blue (MB) and para-nitro phenol (PNP), with performance dependent on catalyst and NaBH₄ concentrations. Further, the catalytic performance of M@CuO is proportional to the presence of a relatively larger amount of CuO NPs within the microgel. Further, the kinetics of the reduction reactions have been studied using ultraviolet–visible spectroscopy.

The effects of electrospinning conditions and the QCS-to-PVA ratio were investigated. To further improve the healing efficiency of nanomat, quercetin was incorporated to polymeric matrix of mat before electrospinning. Mats prepared under optimized electrospinning conditions and at a QCS/PVA ratio of 30:70 (v/v) exhibited uniform, bead-free morphology and demonstrated favorable physicochemical properties, including high porosity (~ 91%), hydrophilicity, and an appropriate water vapor transmission rate.

While both mats exhibited moderate antibacterial activity against E. coli, cytocompatibility assays revealed concentration-dependent biocompatibility with mouse fibroblast (L929) cells. In vivo wound healing studies in rats demonstrated significantly improved wound closure in the quercetin-loaded nanomat group compared to the nanomat and control groups, along with enhanced collagen deposition and epithelial regeneration.

NEs were prepared by high-energy ultrasonication using span 80, tween 80 as surfactants, and lecithin as a ripening inhibitor. Dynamic light scattering analysis indicated that the system remained stable for a period of 8 weeks. Antibacterial activity evaluated by the microdilution assay revealed that NEs showed enhanced antibacterial activity compared to bulk oils. Biofilm inhibition assay using crystal violet staining at sub-MIC concentrations demonstrated that NEs reduced biofilm formation by more than 50%, even at the lowest concentration (1/8 × MIC). Scanning electron microscopy images confirmed decreased bacterial attachment and extracellular matrix in treated samples. Established biofilms were effectively eradicated by both NEs and bulk oils, with the best results achieved by TC nanoemulsion (TC NE) at 1/2 × MIC, resulting in 79.86 ± 1.46% biofilm eradication. The impact of TC NE on pyocyanin production, a virulence factor in <i>P. aeruginosa</i>, was also investigated. The NE inhibited pyocyanin production in a concentration-dependent manner, showing the greatest inhibition (94.76 ± 0.38%) at 1/2 × MIC after 24 h. Finally, the degradation of TC by PAO1 was assessed. The results showed that cinnamaldehyde was converted into the less toxic cinnamic alcohol, with a slower conversion rate in NE-treated samples.

The innovative incorporation of SBMA imparts these hydrogels with superior swelling characteristics and broad temperature-responsive ranges, evidenced by a unique biphasic response to NIPAM content variation.
