    "abstract": "We present a method to realize active optical tips for use in near-field\noptics that can operate at room temperature. A metal-coated optical tip is\ncovered with a thin polymer layer stained with CdSe nanocrystals or nanorods at\nlow density. The time analysis of the emission rate and emission spectra of the\nactive tips reveal that a very small number of particles - possibly down to\nonly one - can be made active at the tip apex. This opens the way to near-field\noptics with a single inorganic nanoparticle as a light source.",
