Breakthrough in Gastric Cancer Treatment: Nanosystem Shows Promise

Researchers from Zhumadian Central Hospital have developed a novel photothermal nanosystem that demonstrates superior cytocompatibility, stimuli-responsive drug release, improved tumor-specific targeting, and efficient cell death of gastric cancer cells. By encapsulating carbon quantum dots (CDs) and the gastric cancer drug camptothecin (CT) in liposomes, the researchers created a multifunctional photothermal nanosystem. The nanosystem was triggered by an NIR laser, resulting in a photothermal conversion efficacy of up to 46.97%. The findings suggest that this approach could enhance the therapeutic efficiency of gastric cancer therapy and offer a potential approach for designing and developing synergistic chemo-photothermal combination therapies.
