Nanoparticles with protein ‘passports’ evade immune system, deliver more medication to tumors
Cancer Nanotechnology Current approaches to chemotherapy leave patients with severe side effects because anti-cancer drugs meant to destroy tumors inadvertently kill healthy cells in the body. But scientists have recently developed nanoparticles that can ferry toxic medications directly to tumors while sparing healthy tissue. Because of their small size, nanoparticles escape from leaky blood vessels that are characteristic of tumors and accumulate in the cancerous tissue. Tumor cells take up the particles which release their toxic contents once inside. …
