Green Synthesis of Curcumin Loaded Carbon Dots as a Sustained Drug Delivery for Anticancer Therapy.

AIMS

To enhance curcumin's bioavailability with the help of carbon dot and piperine, due to its promising anticancer activity.

BACKGROUND

Cancer is a disease condition, where some cells grow uncontrollably, and if not controlled, they spread to other parts of the body. Concerning anticancer agents, curcumin has anticancer properties along with anti-inflammatory, antimicrobial, and antioxidant. Here in this study, the pharmacokinetic property was improved with the help of Carbon Dot encapsulation.

METHODS

Bamboo leaves were used for the preparation of CDs and curcumin was loaded in them and the characterization for particle size, morphology, loading capacity, quantum yield, drug release in vitro studies, and cell viability activity as anticancer activity was done accordingly.

RESULTS

Prepared CDs have a smaller particle size (< 10 nm), good loading capacity, stability, and excellent fluorescence activity. Studies on the release of curcumin have shown that a pH-5.5 solution leads to enhanced curcumin release. The CDs-curcumin shows enhanced toxicity against cancerous cells than the curcumin even at lower concentrations (20, 40, 60, 80, 100 μM).

CONCLUSION

Curcumin can be delivered by CDs, which have the advantages of increased bioavailability, small size, high loading capacity, improved photoluminescence, and biocompatibility. These characteristics can result in improved anticancer activities even at low concentrations.
