Abstract Scope |
Gold nanoparticles synthesized with honey (HM-AuNPs) have desirable features that make them ideal candidates for nanoparticle-assisted photothermal therapy (NA-PTT). However, their photothermal properties have not been previously explored. In this study, we assessed the photothermal properties of the HM-AuNPs under Near-InfraRed (NIR) laser irradiation. We characterised the optical and structural properties of spherical HM-AuNPs, which were synthesised via a chemical reduction method. Then, we performed photothermal measurements in 3 different media: aqueous solution, cell suspensions and agarose gel. Finally, we predicted the temperature and thermal damage profiles of HM-AuNP-filled superficial tumors embedded within normal breast tissue using a Finite Element Method (FEM). Experimental results showed that HM-AuNPs achieved photothermal efficiency of up to 40%, had an average absorption cross-section of (2.15±0.08) × 10-15 m2 and reduced cell viability of MDA-MB-468. Also, complete thermal damage of superficial tumors was predicted. Collectively, the results demonstrate the feasibility of using HM-AuNPs for NA-PTT. |
