Microstructured substrate based on in situ growth of silver particles for copper determination in liquid samples by LIBS

Year: 2026

Type: article

Abstract: , respectively. The signal enhancement achieved with the microstructured substrate fabricated using the in situ growth method can be attributed to the synergistic effect of the nanostructures present in the cellulosic microfibers and the surface enhancement caused by the dense layer of Ag microparticles. The developed analytical strategy was successfully applied to the determination of Cu(II) ions in fortified samples of river water, artificial urine, tea infusion, and canned tea, providing recoveries ranging from 85 to 112 %. These results indicate the effectiveness of a microstructured silver substrate for sensitive detection of metal ions at low concentrations in liquid samples.
