Graphene oxide-mediated photothermal therapy using femtosecond lasers has recently shown promise in treating hepatocellular carcinoma. However, significant work remains to optimize irradiation parameters for specific nanoparticle types and cancer cells improve nanomaterial-mediated anticancer therapy. This study investigated the potential of nGO nGO-PEG nanoparticles (NPs) combined with laser at 515 nm 1030 wavelengths, varying power (0.1 0.2 W/cm2) duration (5 10 min), Conversion efficiency NPs, morphology viability HepG2 normal MDCK after treatments were evaluated an electronic thermometer, phase-contrast microscopy, WST-1 assay. The results revealed that NPs exhibited better than nGO, inducing a temperature increase up 19.1 °C compared 4.7 light. Laser exposure significantly reduced cell viability, most intense conditions (10 min causing decrease 58.2% 43.51% nGO-PEG. Normal showed minimal impact or slight increase, especially Combined treatment induced morphological changes cells, including detachment apoptotic-like characteristics, particularly irradiation. changes, some recovery observed under lower energy conditions. These findings suggest low-energy engineered nanomaterials could provide minimally invasive approach side effects.
