AI Article Synopsis

  • Silver ions significantly lower the energy required to create nanogratings (NGs) on sodium gallophosphate glass.
  • The presence of silver results in smoother NG shapes and a unique dual effect where fluorescence from silver clusters occurs before NG formation.
  • This study is the first to show that noble metal ions can act like catalysts to enhance the creation of NGs, suggesting potential for advancing technology in this area.

Article Abstract

We investigated the influence of silver ions during the direct femtosecond laser-induced formation of nanogratings (NGs) at the surface of a tailored sodium gallophosphate glass. We observed that the silver ions had a remarkable influence because the silver-containing glass showed (1) lower fluence thresholds for the formation of the NGs; (2) much smoother NG shapes; and (3) a bifunctional behavior because fluorescence from laser-induced silver clusters occurs prior to the formation of the NGs. We demonstrate for the first time, to our knowledge, the formation of NGs assisted by noble metal ions, such as ions playing a kind of catalytic-like role that enhances and improves the NG formation and its incubation process. Our innovative approach provides promising potential for further improvements in processes for NG formation.

Background: Dental caries is a prevalent oral health issue primarily caused by Streptococcus mutans, a bacterium that contributes to tooth decay. Antimicrobial agents in dentifrices are often utilized to target these pathogens. Nano silver fluoride (NSF) has emerged as a potential antimicrobial agent due to its ability to inhibit bacterial growth.

Silver drugs have played a vital role in human healthcare for the treatment of infections for many centuries. Currently, due to antibiotic resistance, a potential scenario or the application of silver complexes may arise as substitutes for conventional antibiotics. In this perspective, N-heterocyclic carbene (NHC) ligands have been selected as carrier molecules for silver ions.

Heavy metals are life-threatening pollutions because of their great toxicity, long-term persistence in nature and their bioaccumulation in living organisms. In this work, we performed multivariate curve resolution-alternating least squares analysis of UV-Vis raw spectra received by a colorimetric sensor constructed on mercaptoundecanoic acid functionalized silver nanoparticles (AgNPs@11MUA) to detect Cd, Cu, Mn, Ni, and Zn in water. This combined approach allowed the rapid identification and quantification of multiple heavy metals and showed adequate sensitivity and selectivity, thus representing a promising analytical and computational method for both laboratory and field applications such as environmental safety and public health monitoring.
