Fabrication and Evaluation of Polyacrylate Nanocomposites Embedded With Metal Oxides as Enhanced Multipurpose Nanocarriers for Long‐Term Anti‐Inflammatory and Amazing Antimicrobial Properties

ABSTRACT

The design of super‐antimicrobially active multipurpose nanocarriers as polymeric nanocomposites embedded with metal oxides with sustained drug release is beneficial in medical treatment for controlling inflammation and targeting a wide range of pathogenic microorganisms. Brilliant metal oxide nanoparticles (MOx) involving selenium dioxide, titanium dioxide, and vanadium pentoxide were well prepared in good yields, and their morphologies and structures were specified. Then they were embedded in copolymeric nanocomposites through in situ microemulsion polymerization of (E)‐2‐cyano‐N‐cyclohexyl‐3‐(dimethylamino)acrylamide (CHAA) with methyl methacrylate (MMA), dimethylaminoethyl methacrylate (DMAEMA), and acrylic acid (AA). In addition, ibuprofen was then loaded into the synthesized polymers and their nanocomposites to achieve high drug entrapment efficiency EE%, and its release behavior was studied in various simulated fluids. The produced drug‐loaded polymers and their nanocomposites were characterized using Fourier‐transform infrared spectroscopy (FT‐IR), transmission electron microscope (TEM), X‐ray diffraction (XRD), and thermogravimetric analysis (TG). Well‐defined nanospheres of polymeric‐metal oxide nanocomposites were generated in a size range of 50 nm, with ibuprofen loaded at a high encapsulation efficiency of approximately 97%. In vitro drug release was inspected for the polymer and its nanocomposites revealing that the presence of metal oxide nanoparticles resulted in prolonged and sustained release behavior for wound dressing. The antimicrobial study based on the zone of inhibition against various pathogenic microorganisms showed excellent activity against Bacillus cereus, Staphylococcus aureus, Escherichia coli, Helicobacter pylori, and Candida albicans. These findings validate the potential of these nanocomposites to serve as a viable upcoming antimicrobial agent for the treatment of human ailments.
