Drug-Loaded Nanoparticles

Drug-loaded nanoparticles are tiny particles, typically measuring between 10 and 1000 nanometers, that can be used to deliver therapeutic drugs and other therapeutic agents to target tissues. These particles are typically made of polymeric materials, such as polylactic-co-glycolic acid (PLGA), and are often surface-modified with ligands or targeting agents to improve their ability to target specific tissues or cells. Drug-loaded nanoparticles can be engineered to release their payloads over an extended period of time, making them useful for sustained drug delivery. They can also be designed to protect the drug from degradation in the body, allowing for increased bioavailability. Nanoparticles have been used to deliver a variety of drugs, including chemotherapeutic agents, proteins, peptides, nucleic acids, and even live cells. The use of drug-loaded nanoparticles has enabled researchers to develop novel targeted drug delivery strategies that can improve therapeutic efficacy while reducing unwanted side effects.
