PROCESS FOR PREPARING A PRODUCT TO BE APPLIED IN THE OPTIMIZED PHOTOTHERMAL THERAPY OF HEPATIC TUMOURS

摘要

The invention relates to a process for preparing a product to be applied in the photothermal therapy of hepatic tumours. According to the invention, the process consists in that the gold nanoparticles - GNP - are prepared in an aqueous medium and stabilized with citrate, after which they are functionalized with beta-mercaptoethanol, at a neutral pH, at the room temperature, for 15 min, the thus functionalized gold nanoparticles are then subjected to successive stages of centrifugation and redispersion by ultrasonication in bidistilled water, for removing the secondary reaction products.
