What are Nanoparticles and How are They Used in Drug Delivery?
Nanoparticles are particles between 1 and 100 nanometers in size. In drug delivery, they can be engineered to carry drugs directly to the target cells, minimizing side effects and improving the efficacy of the treatment. For example, nanoparticles coated with specific ligands can bind to cancer cells, releasing the drug directly into the tumor and sparing healthy tissues.
