Abstract
BALM is a new wide field optical microscopy which is remarkably suited for nano enginnering. Most of the time, nano-objects have to be fixed on surfaces in order to be localized, handled, or used in combination with some environmental control. BALM is a surface imaging technique wich combines extreme (say SPR-like) sensitivity with full optical resolution. Moreover, its implementation is confined in the half-space located below the sample, so that the upper half-space remains free for implementing environmental tools such as a fluidic cell, spectroscopic tools such as Raman analysis, local measuring tools such as electrical and SPM probes or local fields of any type. At last, it is a real time technique, hence offering large possibilities for kinetic studies.
Thanks to a close collaboration with Vincent Dreycke, Stephane Campidelli and Renaud Cornut in the LICSEN group of CEA Saclay, the power of the technique in the study of 2D materials was recently demontrated 1 .
The aim of this talk is to forecast the next coming BALM applications, supported by preliminary results obtained with various kinds of nanoparticles, sensor chips and solid liquid interfaces. The first principles of the technique will also be exposed.
