Experimental and theoretical investigation of the photothermal effect in gold nanorods

Abstract

In this work, Gold nanorods (GNRs) were synthesized using seed-mediated route and their photothermal property was investigated experimentally as well as theoretically. The structure and optical properties of the samples...

Gold Nanorod-Decorated Metallic MoS2 Nanosheets for Synergistic Photothermal and Photodynamic Antibacterial Therapy

“…37-1492), respectively[57]. The XRD pattern of AuNRs revealed three main XRD peaks located at 38.2 • , 44.4 • , and 64.6 • , corresponding to the crystal planes of (111), (200), and (220), respectively[58,59]. For MoS 2 @AuNRs, characteristic peaks of 1T-MoS 2 NSs and AuNRs were still exhibited after the decoration of AuNRs onto 1T-MoS 2 NSs.…”

Targeted pH/redox dual-responsive nanoparticles for cancer chemotherapy combined with photodynamic/photothermal therapy

“…Even when the ICG concentration was 10 μg mL −1 , its temperature increased from 18.8 °C to 44.7 °C. According to the experimental results, the ICG concentration of nanoparticles and irradiation duration could be adjusted to make the temperature reach the level that tumor cells could be inhibited, 49 which guided the application of ID@HMSNs-SNH in the photothermal treatment of tumors. Using the previous method and the temperature curve of ID@HMSNs-SNH (ICG concentration was 10 μg mL −1 ), which has been irradiated for 10 min and with the irradiation stopped for 10 min (Fig.…”

NIR-Excitable PEG-Modified Au Nanorods for Photothermal Therapy of Cervical Cancer

“…The stable chemical properties, strong absorption, no photobleaching ability, and adjustable optical properties make gold (Au) nanorods (NRs) promising photothermal agents. , When exposed to NIR light, Au NRs have strong laser absorption, generating heat that increases the local temperature, leads to tumor ablation, and damages the cancer cells. Furthermore, the application for the delivery of Au NR agents can increase the permeability of tumor vessels . To achieve better therapeutic efficacy, surface modification strategies are used to enhance the biocompatibility of Au NRs without reducing the photothermal conversion efficiency. − Cheng et al used the furin-cleavable RVRR peptide-decorated Au NRs (Au-RRVR) to reduce cytotoxicity.…”
