Advances in Nonlinear Light-Matter Interactions in Molecular Media: from Materials to Single Molecules

Advances in Nonlinear Light-Matter Interactions in Molecular Media: from Materials to Single Molecules Joseph ZYSS Molecular Quantum Photonics Laboratory and dAlembert Institute, Ecole Normale Supérieure Cachan, France zyss@lpqm.ens-cachan.fr, www.lpqm.ens-cachan.fr and www.ifr.ens-cachan.fr We will first discuss recent results on new nonlinear optical multi-valued optical memories allowing for high density (e.g. with tensorial multiplicity) optical data storage and opening the way towards new possibilities of light steering for functional entities in biological environment.

Microtools for Biology

A combination of five materials/techniques is providing a new set of tools to use in studying problems of interest in biochemistry and biology. These tools are particularly useful for manipulating the environment of mammalian cells attached to surfaces. Self-assembled monolayers (SAMs) of alkanethiolates on gold control the character of interfaces; "inert surfaces" (surfaces that do not adsorb proteins) do not allow cells to attach, and thus allow them to be positioned at specific locations and with specific shapes on surfaces.
