Nanomedicines work by utilizing the unique properties of nanoparticles to improve the efficacy and safety of therapeutic interventions. These particles can be engineered to carry drugs, genes, or other therapeutic agents directly to specific cells or tissues. By doing so, they minimize the side effects associated with traditional treatments and enhance the therapeutic outcome. For instance, liposomes and dendrimers are used to encapsulate drugs, protecting them from degradation and allowing for controlled release.
