In this paper, we use integrated plasmonic glass nanotips for the detection of chemical molecules at very low concentration level by means of extinction spectroscopy. For this we employ on nanosensors based on localized surface plasmon resonance. Furthermore, we show that the sensitivity of these nanosensors is increased by a factor of two orders of magnitude compared to the sensitivities reported...
Efficient nanochemosensors designed by electron beam lithography and based on localized surface plasmon resonance excited on noble metal nanocylinders are presented. Using localized surface plasmon resonance spectroscopy, we report here a high sensitivity corresponding to a density of about 18×10 −21 mol of adsorbate per nanocylinders, we present the results obtained with gold and silver nanoparticles...
