Gold nanoparticles scatter visible light very well, and so can readily be imaged by darkfield microscopy.  In this talk I will describe how to make these particles resonant with different frequencies of light; what kind of imaging experiments can be done with them, with cells; and finally show more recent work that showcases the surprising result that gold nanoparticles can influence cell behavior, even if the particles are not in the cells.
