Abstract Materials and alternative therapeutic agents are of high demand due to ever growing risk epidemics chronic ailments. In this study, we present Ag-doped ZnO-TiO2 nanocomposites as photocatalysts antioxidants that can act possible therapeutics for many non-communicable diseases. The were fabricated through sol-gel synthesis underwent thorough examination employing UV spectroscopy, Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM). We conducted a more in-depth analysis their photo-catalytic activity assessed antioxidant capability by reducing assay hydrogen peroxide scavenging activity. findings demonstrate the feasibility producing exhibit excellent performance enhanced characteristics. Photocatalytic revealed Ag doping increased efficiency dye degradation 100% against 80% undoped ZnO-TiO₂. Moreover, optical badgap decreased from 2.48 eV 2.31 in presence doping, suggesting better visible light absorption. Antioxidant was ~ 35%, power recorded 40% reduced absorbance comparison ascorbic acid standard. This suggests they possess significant potential diverse applications medicine bring forth solutions incurable medical ailments challenging currently.

Hydroxyapatite nanoparticles (HAp NPs) were synthesized with Muntingia calabura leaf extract as solvent and eggshell waste a calcium source. The irregular rod-like, visualized by FESEM, while EDX XPS studies confirmed the formation of hydroxyapatite. HAp NPs polycrystalline highly thermostable per XRD TGA respectively. FTIR stable coating plant phytochemicals onto NPs. Congo red adsorption using nanoadsorbent was optimized central composite design, wherein 89.96% 33.18 mg/L dye adsorbed in 137 min at 180 RPM. process line pseudo-second-order model Freundlich isotherm indicated chemical adsorption. feasible, exothermic, spontaneous thermodynamic studies. capacity stood maximum 217 mg/g, indicating its superiority among other adsorbents reported earlier. It is evident from convincing results that present investigation may have major role developing novel for removal out wastewater streams.

Abstract In recent years silver nanoparticles (Ag NPs) gained increased and widespread applications in various fields of industry, technology, medicine. This study describes the green synthesis applying a low-molecular-weight fraction (LMF) Royal Jelly, nanoparticle characterization, particularly their antibacterial activity. The optical properties NPs, characterized by UV–Vis absorption spectroscopy, showed peak at ~ 430 nm. hydrodynamic radius concentration were determined complementary dynamic light scattering (DLS) tracking analysis (NTA). particle morphology was investigated using transmission electron microscopy (TEM), crystallinity confirmed X-ray diffraction (XRD). activities evaluated utilizing Gram-negative Gram-positive bacteria colony counting assays. growth inhibition curve method applied to obtain information about corresponding minimum inhibitory concentrations (MIC) bactericidal (MBC) required. Obtained results that (i) sizes Ag NPs are increasing within increase ion precursor concentration, (ii) DLS, agreement with NTA, most particles have dimensions range 50–100 nm; (iii) E. coli more susceptible all NP samples compared B. subtilis .
