Nanodiamonds synthesis using sustainable concentrated solar thermal energy: applications in bioimaging and phototherapy.There is a renewed interest in nanodiamonds and their applications in biology and medicine, especially in bioimaging and photothermal therapy.  This is due to their small size, chemical inertness and unique photo-properties such as bright and robust fluorescence, resistant to photobleaching and photothermal response under near infrared (NIR) irradiation.  The synthesized nanodiamonds also exhibited dose dependent photothermal response under NIR irradiation.
