Abstract

This work reports a new nano platform made from natural materials for phototherapy (PT) applications. For this purpose, calcium carbonate nanoparticles (NPs) derived from Persian Gulf squid bones as a drug carrier, Syzygium cumini (dye extracted from the fruit of the Persian Gulf trees) as a photosensitizer, and Doxorubicin as a chemotherapy (CHT) drug have been used. In addition, copper NPs were added to the above nanocomposition to increase the efficiency of photothermal (PTT) treatment. For PT, samples were irradiated by an 808 nm laser (1 W cm-2). The results show that nanocomposites play an influential role in the reactive oxygen species process, and an increase of 21 degrees in temperature during 15 min of laser radiation is effective in photodynamic (PDT)/PTT therapy. The drug loading capacity of the nanocomposite was calculated as 49%. This new nanocomposite for simultaneous PDT/PTT/CHT holds great promise for future cancer treatment due to its excellent potential in treatment and reduced systemic toxicity.

Keywords: Syzygium cumini; calcium carbonate; chemotherapy; photodynamic; photothermal; squid bone waste.
