Application

Gold nanoparticles are extensively used in biomedical research due to their biocompatibility, facile conjugation to biomolecules and unique optical properties arising from surface plasmon resonance. The presence of spiked nanoantenna-type shapes in NanoUrchins enhances the plasmonic extinction resonance effect which improves the optical limiting effects
