DESCRIPTION
The surface plasmon microscope is a high resolution microscope allowing intracellular and extra-cellular structures imaging without exogenous contrast or
fixation processes agent, which may modify the sample. Amplitude and phase image reconstruction offer the possibility to detect cytoskeleton filaments, vesicules, nucleus, nucleolus and to have a local measurement of their density and their size. Combination of this microscope with fluorescence or atomic force microscopy offers a complete and versatile tool for Multiscale imaging of nano and microstructures.
This automatized microscope offers a sub wavelength resolution imaging, which can be used in others fields than biology like microfluidics, materials….

STAGE OF DEVELOPMENT
Design of a low cost microscope for biomedical applications.
Several samples studied:
• Metalic and dielectric nanoparticles (200 nm - 20 nm): latex, gold, in air and in water
• Human cells: whole cell, internal structure

INTELLECTUAL PROPERTY
3 patents pending in EP and USA
Priority dates: December 11, 2007 (FR0759716)
March 12, 2008 (EP08305052)
December 12, 2009 (FR0950878)

ADVANTAGES / NOVELTY
• Label free detection and imaging
• Offset signal analysis

• High sensitivity: detection of nanoparticles (down to 10 nm)
• Single molecule observation
• Compatible with live cell imaging

APPLICATIONS
• Cellular biology: cellular adhesion, inter-intra cellular trafficking, blood cytology, cell morphotyping and counting
• Biosensors: high throughput biosensors microscopy
• Microfluidic: mixing dynamics in confined systems, boundary layer, wetting, unwetting
• Materials : thin films, nano-objects characterization and detection

COLLABORATION TYPE
PULSALYS looks for industrial partners and offers to grant patents licence.
