Gold, silica, iron oxide, and poly-lactic-co-glycolic acid (PLGA) nanoparticles are revolutionizing nanomedicine in a variety of fields, from oncology and immunology, to neurology, infectious disease, and more. Researchers and commercial organizations alike are harnessing the unique properties of these nanoparticles to transform therapeutic treatments, drug delivery, and theranostics.

Gold nanoshells absorb and scatter light, enabling targeted cell destruction in photothermal therapy while providing exceptional stability and biocompatibility. The tunable optical properties of gold nanorods make them ideal for applications in imaging and photothermal therapy. Iron oxide nanoparticles, with their magnetic properties, facilitate targeted delivery, enhance drug accumulation at specific sites, and invoke hyperthermia. Through their spacious internal structures, mesoporous silica nanoparticles provide efficient drug encapsulation and controlled release. PLGA nanoparticles can also encapsulate a wide range of drugs for controlled systemic and local delivery in a highly biodegradable platform.

These versatile nanoparticles are propelling nanomedicine forward, with potential for improved therapeutic outcomes and enhanced patient care.
