In recent years, the invention of polymers have attracted attention due to their unique properties. (E)‐2‐cyano‐N‐cyclohexyl‐3‐(dimethyl amino) acrylamide (CHAA) is a new type of functional monomer created by the usage of 2‐cyano‐N‐cyclohexylacetamide (3) and dimethylformamide‐dimethylacetal (DMF‐DMA) utilized microwave energy as a green technology. In addition, polymers with significant nanosphere groups were obtained by polymerizing a new synthetic monomer (CHAA) with methyl methacrylate (MMA), dimethylaminoethyl methacrylate (DMAEMA) and acrylic acid (AA) using microemulsion polymerization technology. These polymer nanospheres were approved by different spectroscopic analyzes, such as FT‐IR, TEM, TGA, and H1NMR. New structurally defined poly (MMA/DMAEMA/AA/CHAA) nanospheres with an equivalent spherical diameter close to 50 nm and high thermal stability were obtained. In addition, these new polymer nanospheres exhibit good electrochemical performance and greater specific values compared to compound (CHAA) or poly (MMA/DMAEMA/AA). This is very important for the supercapacitor due to the fact that the voltammetry plots of these nanospheres display a well‐known hysteresis cycle. The newly synthesized polymer nanospheres exhibited antibacterial activity, which was confirmed by molecular docking simulations with different affinities. Also, the DFT investigation of the polymeric nanosphere was optimized utilizing B3LYP/6‐31(G) basis set and determination physical decribitors.

“…Obviously, the formulated nanocomposite presented excellent antimicrobial activity against all the microbial populations recorded, such as 54% for filamentous fungi (Figure 7a). According to the mode of action, antimicrobial activity was gained from synergetic ZnO@Fe 3 O 4 , which has wonderful antibacterial activity that is pertinent to the synergetic impact of the antimicrobial activity of both metals, which is triggered by a larger free-energy change, leading to the increased formation of reactive oxygen species (ROS) [20,21,74]. Additionally, casein plays a role in antimicrobial activity via binding with the growth regulators of microbes as electrolytes and deactivating cell progression [75].…”

Biocompatibility is a major concern for promising multifunctional bioactive materials. Unfortunately, bioactive materials lack biocompatibility in some respects, so active ingredient formulations are urgently needed. Bimetallic nanoparticles have demonstrated drawbacks in stabilized biocompatible formulations. This study examined the preparation of biomaterial-based multifunctional biopolymers via an eco-friendly formulation method using ultrasound. Bimetallic zinc oxide/iron oxide (magnetic form) nanoparticles (ZnO@Fe3O4NPs) were formulated using casein and starch as capping agents and stabilizers. The formulated nanocomposite was characterized using ultraviolet–visible spectroscopy (UV-vis), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), and high-resolution transmission electron microscopy (HR-TEM). Herein, the formulated nanocomposite was shown to have a thermally stable nanostructure, and the bimetallic ZnO@Fe3O4 NPs were measured as 85 nm length and 13 nm width. Additionally, the biocompatibility test showed its excellent cytocompatibility with Wi 38 and Vero normal cell lines, with IC50 550 and 650 mg/mL, respectively. Moreover, the antimicrobial activity was noted against six pathogens that are represent to the most common pathogenic microbes, with the time required for killing of bacteria and unicellular fungi being 19 h and 61 h for filamentous fungi with remarket an excellent antioxidant activity.

“…Furthermore, Waste-derived natural polymers attract considerable attention to achieve zero waste because they are renewable, abundant, biodegradable, and nontoxic 14 – 16 . In particular, cellulose, which can be obtained from renewable agriculture waste, is one of the most appealing candidates owing to its biodegradability, biocompatibility, and low cost.…”

The reaction of cyanoethyl cellulose with para-bromo diazonium chloride resulted in the creation of a novel bromo-containing cellulosic (MCPT). The dispersion stability of MCPT has been improved by its dispersion into 1% waterborne polyurethane acrylate (WPUA). TEM, particle size, and zeta potential were used to track the dispersion stability of aqueous MCPT and MCPT in 1% WPUA and particle size. The prepared MCPT has been utilized as a unique green colorant (dye) for the printing of cotton, polyester, and cotton/polyester blend fabrics using a silkscreen printing technique through a single printing step and one color system. Color improvement has been achieved by printing different fabrics with a printing paste of MCPT dispersed in 1% WPUA. The MCPT and MCPT in 1% WPUA printed fabrics were evaluated for rubbing, light, washing, and perspiration fastness, UV blocking activity, and antibacterial activity. These findings were established through structural optimization at the DFT/B3LYP/6-31 (G) level and simulations involving several proteins.
