Surface treatment with silver particles isles on Titanium cp: study of antimicrobial activity

Abstract

During the last decades, researchers have been growing the interest in surface treatment with an antimicrobial agent. Silver nanoparticles (AgNPs) are widely used in biomedical fields due to their potent antimicrobial activity. So, in this study was investigated silver particles (isles) coated on titanium surface for dental and orthopedic application. Silver particles coating process on titanium surface were performed via sputtering that is a plasma-assisted deposition technique with and titanium without treatment was applied as comparing standard. Plasma treatment parameters were optimized so that the result was not a thin film of Ag but dispersed particles of Ag on the Ti-cp surface. The alloy surfaces were investigated using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). In order to investigate antibacterial potential Staphylococcus aureus and Escherichia coli have been used at Agar diffusion assay. The results were analyzed by analysis of variance (ANOVA) in order to verify significant difference antimicrobial activity between samples that have shown no difference between the surfaces studied treatments. For silver deposition scattered particles (isles) over titanium surface for a 10-minute treatment, EDS revealed by silver clusters that the particles were not properly scattered onto surface, hence, the low effectiveness in antibacterial activity.

A Review of Children’s Prosthetic Self-hygiene Using Antibacterial Silver Nanoparticles (AgNPs)

“…One of the key mechanisms contributing to the antimicrobial activity of AgNPs is the release of silver ions (Ag + ). Upon contact with bacterial cells, it can release Ag + ions, which exhibit potent antimicrobial effects (Prokopovich et al, 2013;Capellato et al, 2020;Piras et al, 2020). The released Ag + ions can interact with various cellular components, including proteins, enzymes, and DNA.…”

“…The potential applications in healthcare are vast and hold great promise for addressing numerous challenges. In the context of self-hygiene of sports prostheses for children, it can play a crucial role in preventing microbial colonization and reducing the risk of infections (Capellato et al, 2020;Ghilini et al, 2021). Incorporating AgNPs into the design and…”
