Marine shrimp shell, a member of the Caridean biological family, is an aquatic crustacean used in aquariums with wide range pharmacological activities. This study's success development natural resource silver oxide/iron oxide nanocomposite (NCs) (AgO/Fe<sub>2</sub>O<sub>3</sub> NCs) prepared by combining marine shell extract Ag<sub>2</sub>NO<sub>3</sub> and FeCl<sub>3</sub> salt via PLA (Nd-YAG) process. AgO/Fe<sub>2</sub>O<sub>3</sub> NCs are vital to antibacterial because they kill germs maintain disease-free environment. XRD analysis, FE-SEM pictures, TEM images, EDS, mapping, FTIR spectra were employed investigate NCs. The data indicates that have face centre cubic F.C.C. structure crystallite sizes between 9.6 19.5 nm. Moreover, according data, NCs' average diameters 10 20 nm revealed nano-spherical shape. According scans, varied size from 15.4 23 spherical aggregation form. Ag, Fe, O occurrences present high-purity NCs, as demonstrated EDS their picture. In spectra, peaks related symmetric stretching vibrations Ag-O I-O bonds can be seen at 726 cm-1. inhibition zones evaluated using diffusion. measured 29 13.5 mm for gram-positive bacteria <i>Staphylococcus aureus</i> epidermidis</i>) 40 gram-negative (<i>Escherichia coli</i>); <i>Candida</i>, zone (IZDs) value was 42 mm.

A pioneer microbial-based synthesis of various nanoparticles is gaining more attention due to their potent applications in industries. The magnetic (M-nps) were fabricated for the first-time using cell free extract Trichoderma asperellum. M-nps bioprocess optimization was performed Response Surface Methodology and Artificial Neural Network.The significantly (P < 0.05) affected by pH, stirring speed, incubation period. displayed a strong antibacterial efficiency against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, Staphylococcus aureus dose-dependent manner. minimum inhibitory concentration (MIC) E. P. S. respectively found be 25.0, 6.25, 3.125 µg/ml. While bactericidal (MBC) 12.5, 6.25 highest inhibition zone 22 mm recorded B. subtilis at 80 µg/ml with MIC MBC sodium alginate/M-nps microbeads successfully prepared without any crosslinkers. exhibited adsorptive (84.32%) malachite green pH 8.0, dose 0.1 g, time 60 min. experimental data superlative fitted Langmuir's isotherm, hinting monolayer adsorption MG molecules 117.65 mg g-1 capacity. regenerated beads continued up-to six consecutive cycles maintained than 90%, indicating multiple use material. Hence, display promising application combating bacterial pathogens. can employed as an alternative eco-friendly, highly efficient, sustainable, low-cost biosorbent removing contaminants from wastewater.
