Medical illustration of nanoparticles delivering chemotherapy drugs directly to a tumor while sparing healthy tissue.

Traditional chemotherapy faces a fundamental limitation: most anticancer drugs are toxic to both malignant and healthy cells. Systemic distribution leads to well-known side effects — hair loss, immune suppression, gastrointestinal damage, and organ toxicity. The challenge is not only killing cancer cells but doing so selectively. Nanoparticle drug delivery systems aim to change this equation. … Read more
