In cancer treatment, nano medicines are designed to target cancer cells specifically, minimizing damage to healthy cells. This is achieved through various mechanisms:
- Targeted Drug Delivery: Nanoparticles are engineered to deliver chemotherapy drugs directly to cancer cells, enhancing the drug's efficacy and reducing systemic side effects. - Enhanced Permeability and Retention (EPR) Effect: Tumors often have leaky vasculature, which allows nanoparticles to accumulate more in tumor tissues than in normal tissues. - Controlled Release: Nano medicines can be designed to release their therapeutic payload over time or in response to specific stimuli, such as pH changes or enzymatic activity in the tumor microenvironment.
