Detection and characterization of colloidal silver nanofluids by photothermal techniques

Year: 2025

Type: article

Abstract: In this work, Ag 0 nanoparticles (NPs) were synthesized and detected by flow-injection analysis coupled to collinear dual-beam thermal lens spectrometric (TLS) detection. The estimated limit of detection was 0.8 µg/L. The use of the IonPac Cryptand G1 column enabled Ag 0 NPs detection in the presence of interfering ions normally present in water. Ag 0 nanofluids (NFs) were further characterized by time-resolved TLS and beam deflection spectrometry to determine the NFs thermal diffusivity and conductivity. The applied methods were found to be fast, simple, reliable, and highly sensitive.
