The invention relates to an active probe for near-field optical microscopy, characterized in that it includes a metal or metallized tip (PM) at the apex of which a nanoscale body (NB) is located, the body having a polymer matrix capable of, or containing a host (MH) capable of, emitting under illumination, light (SH) at a wavelength different from that of the illumination. A process for manufacturing such a probe is also provided.

Triphenylamine derivatives useful as fluorophores in biology, in particular for two-photon microscopy; and compositions comprising these derivatives, to the use of these compositions and of the derivatives themselves for labelling biological molecules (or 'biomolecules') such as nucleic acids, oligonucleotides, proteins, polypeptides, plasmids, and the like, for their examination in particular by two-photon microscopy, and to biomolecules labelled with the said derivatives.

The invention concerns a method for treating a fluid. According to the invention, the fluid is contacted with a substrate at the surface of which there is a network of organic molecules, hereafter referred to as 'network molecules'. There is a central core and at least one lateral arm, the molecules being adsorbed at the surface of the substrate. The invention also concerns a two-dimensional molecular sieve formed by the substrate at the surface of which a network of network molecules is adsorbed. The invention further concerns a module for treating a fluid including a circulating device for the fluid to be treated, the device containing one or more two-dimensional molecule sieves.

The present invention relates to an indirect-gap semiconductor substrate, the gap being greater than that of silicon and preferably greater than 1.5 eV, to its use for imaging a specimen by photon-emission scanning tunnel microscopy, and to a photon-emission scanning tunnel imaging method using such an indirect-gap semiconductor substrate. Advantageously, the indirect-gap semiconductor substrate is made of silicon carbide. The present invention also relates to devices for implementing the imaging method according to the invention.

A transparent, organic polymer substrate organized for optical frequency conversion is prepared by subjecting a material of a transparent, organic polymer which incorporates therein transparent, active organic molecules which have a second order, microscopic, optical nonlinearity to the simultaneous action of a first laser beam at fundamental frequency .omega. and a second laser beam of second harmonic frequency 2 .omega. for a time adequate to induce a second order, macroscopic nonlinearity in the transparent active organic molecules in the structure.
