The Efficacy of Silver Nanoparticles in Combating Biofilm Formation by Uropathogenic Escherichia coli

Journal of Pure and Applied Microbiology, 2023
Uropathogenic Escherichia coli (UPEC) is prevalent in urinary tract infections (UTIs). UPEC’s biofilm production enables it to invade and persist in the uroepithelium, leading to recurrent UTIs.

AgNPs-ion release is sufficient to exert a bactericidal effect over E. coli cultures.

, 2016
By dialysis experiments, confined bacteria was killed by ions released from CEOBACTER (A). No release of AgNPs were shown in culture media inside and outside dialysis sacks (B). Ag ions was measured by ICP analysis.

Proposed antibiofilm mechanism of plant mediated AgNPs.

, 2021
1) AgNPs has electrostatic interaction with the cells and disturb the biofilm formation; 2) AgNPs target the eDNA to eliminate bacterial biofilm; 3) AgNPs degrade the EPS formation and breaks the biofilm mat; 4) AgNPs inhibits the signal produced by the ...

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

Advanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Silver Nanoparticles in Donkey Semen Stored at 17°C: Effect on Sperm Parameters and Bacterial Growth. [PDF]

Reprod Domest Anim
ABSTRACT The aim of this study was to evaluate the effect of silver nanoparticles (AgNPs) on donkey sperm parameters and their antimicrobial efficacy on bacteria isolated in the presence of antibiotics. Nine donkey ejaculates were collected and stored in a skim‐milk extender at different AgNPs concentrations (0, 0.01, 0.8, 1.6 and 3.12 mg/mL) at 5°C or
