Cellular targeting is a research area focused on developing methods to accurately deliver therapeutic agents or imaging agents specifically to certain cells or tissues within the body. This approach allows for more precise and effective treatment of diseases, while minimizing side effects on healthy cells. Techniques for cellular targeting may involve using specific molecules that can bind to receptors on the target cells, as well as nanoparticles or other carriers that can deliver drugs directly to the desired location. This area of research holds promise for improving the efficacy and safety of various medical treatments.
