Bacterial infection of the wound could potentially cause serious complications and an enormous medical financial cost to rapid emergence drug-resistant bacteria. Nanomaterials are emerging technology, that has been researched as possible antimicrobial nanomaterials for inhibition enhancement healing. Graphene is 2-dimensional (2D) sheet sp2 carbon atoms in a honeycomb structure. It superior properties, strength, conductivity, antimicrobial, molecular carrier abilities. its derivatives, oxide (GO) reduced GO (rGO), have antibacterial activity damage bacterial morphology lead leakage intracellular substances. Besides, management, Graphene-platforms be functionalized by different agents such metal-nanoparticles, natural compounds, antibiotics. The structure can absorb near-infrared wavelengths, allowing it used photodynamic therapy. Therefore, Graphene-based material inhibit pathogens skin infections destroy their biofilm community, which one biggest challenges treating infection. Due agglomerated structure, hydrogel entrap stack bacteria; thus, prevents initial attachment formation. sharp edges extracellular polymeric substance surrounding ruin biomass As well as, Chitosan synthetic polymers collagen polyvinyl alcohol (PVA) also attracted great deal attention use with dressing material. To this end, multi-functional based on blends considered valid non-antibiotic compounds useful against improvement Finally, global care market size was valued at USD 20.8 billion 2022 expected expand compound annual growth rate (CAGR) 5.4% from 2027 (USD 27.2 billion).

Abstract In this study, a new nanocomposite was created by combining copper-doped nickel ferrite (NiCuFe 2 O 4 ) nanoparticles with MCM-48 (Mobil Composition of Matter No. 48) on graphene oxide (GO) substrate functionalized poly(ρ-phenylenediamine) abbreviated as (PρPD). This developed to investigate its potential for enhancing the function supercapacitor in energy storage. Following NiCuFe @MCM-48 preparation, Hummer’s technique GO applied. In-situ polymerization @MCM-48/GO ρ-phenylenediamine (ρPD) presence ammonium persulfate (APS) produced PρPD, conductive polymer. Structural characterization includes FTIR, XRD, VSM, TGA-DTG, EDX, and FE-SEM. Results from BET indicate pore size increase up 5 nm. Fast ion penetration higher storage capacitor material are explained this. Additionally, nanocomposite’s electrochemical performance evaluated using GCD CV tests. The @MCM-48/GO/PρPD has specific capacitance 203.57 F g −1 (1 A ). Furthermore, cyclical stability is essential applications. retains 92.5% original after 3000 cycles, indicating outstanding stability.
