Examining nanoparticles with different laser wavelengths in liquid environment

Abstract

AbstractThe focus of this present investigation is to examine the heating characteristics of gold and silver nanoparticles at different laser wavelengths. Comparative research on the heat transfer studies with gold ultrafine particles and silver ultrafine particles was undertaken to determine an appropriate frequency and substance with greater photothermic effectiveness for hyperthermic use in cancer therapy. At 488 nm and 540 nm, gold nanoparticles are found to be greater photothermally efficient than silver nanoparticles. The 540 nm laser burns gold nanoparticles greater than the 488 nm laser. Silver nanoparticles, on the other hand, showed a slightly lower temperature increase at 540 nm than at 488 nm. In the diametral surface range of 0–50 nm, size‐dependent impact research showed that the absorbance effectiveness of single gold nanoparticulate with larger diameters is larger than those with lower diameters.
