United StatesScientists have developed a new nanoparticle-based method that uses a patient’s own copper supply within tumors to induce cancer cell death, potentially reducing harmful side effects associated with traditional metal-based treatments. The study, conducted by researchers at Guizhou Medical University and published in *Biomedical Analysis*, explores 'cuproptosis'—a process where copper disrupts cancer cell survival. Previous approaches required externally added copper, raising toxicity concerns, but this new system delivers a copper-binding agent directly to cancer cells using biodegradable PLGA-PEG nanoparticles modified with the iRGD peptide to target tumors more effectively. Lab tests showed the nanoparticles successfully delivered TPEN to cancer cells, causing greater toxicity to malignant cells while minimizing harm to healthy tissue. While the results offer promise for improving cancer therapy selectivity, experts note substantial hurdles remain before clinical application.
