“…The CD is formed from citric acid, ammonium citrate, polyamines, and sugars. The CDs are now used because of their facile production, water dispersibility, minimal cytotoxicity, and great biocompatibility. , Size and surface charge make CDs efficient against drug-resistant bacteria, intracellular microorganisms, and biofilms . CCM-CDs are effective against the swine epidemic diarrhea virus because they inhibit viral entry, negative-strand RNA synthesis, viral budding, and reactive oxygen species (ROS) accumulation.…”

This study examines the potential anticancer properties of curcumin carbon nanodot-decorated chitosan nanoparticles (CCM@CD/CS-NP) in HepG2 hepatocellular carcinoma cells. CCM@CD/CS-NPs were synthesized, and their size, morphology, and elemental analysis were characterized. The combination of curcumin carbon dots and chitosan in the form of a nanoparticle has a number of benefits, including improved solubility and bioavailability of curcumin, enhanced stability and biocompatibility of carbon dots, and sustained release of the drug due to the mucoadhesive properties of chitosan. The purpose of this research was to examine the efficacy of curcumin carbon dot-decorated chitosan nanoparticles as an anticancer agent in the treatment of HepG2 cell lines. The cell proliferation and apoptosis-related gene expressions in HepG2 cells were assessed to investigate the potential use of nanoparticles in vitro. The IC50 value for the inhibitory effect of CCM@CD/CS-NPs on cell growth and proliferation was determined to be 323.61 μg/mL at 24 h and 267.73 μg/mL at 48 h. Increased caspase-3 and -9 activation shows that CCM@CD/CS-NPs promoted apoptosis in HepG2 cells. It was also shown that the overexpression of Bax and the downregulation of Bcl-2 were responsible for the apoptotic impact of CCM@CD/CS-NPs. The nanoparticles have been shown to have minimal toxicity to normal liver cells, indicating their potential as a safe and effective treatment for HepG2. These novel nanomaterials effectively suppressed tumor development and boosted the rate of apoptotic cell death.
