Nanostars

Nanostars are nanoscale structures characterized by star-like geometries, typically composed of metals such as gold or silver. Their unique morphology enhances surface area and localized surface plasmon resonances, making them highly effective for applications in fields like biomedical imaging, drug delivery, and photothermal therapy. In diagnostics, nanostars serve as contrast agents for imaging techniques, while in therapeutics, they can selectively target and destroy cancer cells when exposed to near-infrared light. Their tunable optical properties also facilitate their use in sensing applications, allowing for the detection of biomolecules and environmental pollutants at low concentrations.
