Nanolane Surf optical slides

Click2Contact

Optical microscopes have traditionally been limited to samples in the submicron size range. With the development of Surf slides from Nanolane, images of nanometric samples from regular light microscopes have been made possible.

The optical slides are based on the control of the polarisation of the light. These characterisation tools use the label-free SEEC (surface enhanced ellipsometry contrast) optical technique. The technique not only allows users to track changes at surface but also offers live visualisation with high lateral resolution and thickness measurements (from 0.1 to 300 nm).

Nanometric films (down to 0.3 nm) and isolated nano-objects (down to 2 nm diameter) can be observed in air or in water in real time without any labelling. The technique can be integrated in existing analysis equipment such as atomic force microscopy, Raman spectroscopy, etc.

SEEC microscopy is a fast and powerful technique for understanding surface phenomena via live nanoscale visualisation of films/objects (nanolayer, biofilm, biochip, nanotubes, nanoparticles). Applications include topography, molecular adsorption/desorption, (bio)films build-up/degradation, kinetics of film morphological changes, dispersion, biological layers interaction, swelling effect and more.
