Abstract In the current study, a decahedron-like silver nanostructure (D-AgNs) was successfully created in an aqueous solution presence of Polyvinylpyrrolidone (PVP) as capping agent using gamma-radiolysis approach without use reducing agent. The synthesized D-AgNs were characterized various analytical tools such UV–Vis. spectroscopy, SEM, XRD, HRTEM, EDX and FTIR. absorption spectra showed considerable surface Plasmon resonance (SPR) bands at 350–600 nm, indicating that colloidal had been synthesized. HRTEM image demonstrates well-dispersed uniformly decahedral shapes are well separated from each other. produced nanoparticles effectively stabilized by PVP through interactions, confirmed FTIR anlaysis. synthesis gamma radiation accomplished, addition its antimicrobial potential, antibiofilm activity, effect UV rays assessed. addition, protein leakage assays SEM imaging employed to analyze reaction’s mechanism. A wide variety bacteria, including S. aureus , P. aeruginosa C. albicans deactivated D-AgNs. assay, inhibited biofilm formation (89.58%), E. coli (80.35%), aureginosa (78.45%). After investigating on growth curve aureus, we concluded affect reduced be 0.125. holes cell membrane is explained fact amount cellular released bacteria directly proportional concentration D-AgNs, which determined 259.25 µg/ml equal 1.0 mg/mL.

Hydroxyapatite (HAp) is widely used in biomedical applications due to its biocompatibility, osteoconductivity, and bioactivity. However, low mechanical strength, tendency toward rapid corrosion, lack of bactericidal properties present significant limitations applications. This study aimed improve the HAp by reinforcing it with multi-walled carbon nanotubes (MWCNTs) doping silver nanoparticles (AgNPs) silver-core selenium-shell (Ag@SeNPs). Ocimum basilicum extract was as both a reducing stabilizing agent synthesis using an environmentally friendly non-toxic method alternative traditional methods. The synthesized HAp, HAp/MWCNT, Ag-HAp/MWCNT, Ag@Se-HAp/MWCNT nanocomposites were characterized TEM, SEM, XRD, Raman spectroscopy, BET analysis. analysis showed reduction surface area from 109.4 m2/g for pure 71.4 m2/g, 47.5 35.3 HAp/MWCNTs, Ag- Ag@Se-HAp/MWCNTs, respectively.

Abstract The expanding threat presented by developing pathogenic multidrug-resistant (MDR) bacteria calls for an urgent need research, particularly given the growing concern global public health. Bimetallic nanoparticles (NPs) have potential to be utilized a broad variety of pharmacological and biological applications because their outstanding antibacterial activity at low concentrations continuous phase stability. This is especially true when it comes preventing MDR from invading. Several synthetic methods producing bimetallic NPs range analytical (used characterize them) are covered in this brief communication paper. Additionally, I tried highlight literature review on antimicrobial capabilities several synthesized NPs. final section discussed structure mechanism action against bacteria. Electrostatic interaction, damage cell membranes, change enzymes proteins, oxidative stress production reactive oxygen species (ROS), binding proteins that disturbs electron transport chain homeostasis, signal transduction suppression, genotoxicity some possible associations with phenomenon being studied.
