Consortium

Consortium

The starting point of the project is the complementary knowhow of the consortium with the capability of UM (University of Montpellier) to realise LSPR structures based on InAsSb/GaSb heterostructures, the expertise of UTT (University of Technology of Troyes) in plasmonics including nanofabrication and infrared near-field characterisations, and of SiKÉMIA (SME) for the surface activation and bio-functionalisation.

First, UM and UTT will design, realise, characterise and optimise the LSPR structures. Secondly, SiKÉMIA will propose the most adapted chemical ligand between organophosphorous and organosilyl compounds to attach the selected biomolecules (biotin streptavidin, antibody, etc.) to study on InAsSb and/or GaSb. In the same time, UM will propose a microfluidic circuit to drive molecules to the LSPR sensor and accurately control the analyte volume and decrease the limit of detection of the sensor. Finally, UM and SiKÉMIA will realise the biosensing proof-of-concept by coupling a broad-band light source directly to the LSPR biosensor or via a waveguide supporting the LSPR biosensor. The reflected or transmitted signal will be analysed by a FTIR spectrometer to obtain the SEIRA or SPR signal.

University of Montpellier

University of Montpellier (UM) is ranked among the first ten scientific universities in France. The present project will be managed by UM which is fully experienced in this field with dedicated staff in legal, financial and administrative issues. The NanoMIR group from the electrical engineering department (IES) has internationally leading expertise in the growth of III-Sb based heterostructures for optoelectronics applications.

SiKÉMIA

SiKÉMIA is a French company with expertise in material surface functionalization. Surface Functionalization provides new properties to the surface of a material. These properties can be physical, chemical or biological. SiKÉMIA technology focuses on chemical surface functionalization via coupling agents. SiKÉMIA proposes a specific methodology which combines the development of innovative coupling agents with chemical surface functionalization. This approach offers a much broader spectrum of surface functionalities and substrates than other existing methods.

University of Technology of Troyes

The LNIO  lab (80 people) of UTT, set‐up twenty years ago,  has developed during a decade an international expertise in Near‐Field optical Microscopy and Spectroscopy. During the last seven years, the LNIO has widened its field of research to cover nanosensors, nanomaterials, local structuring of photosensitive polymers, nanoplasmonics and nanophotonics. In this SUPREME-B project, the involved group in the UTT-LNIO is performing IR near-field characterization of the structures developed by NANOMIR, advanded holographic paterning and the related electromagnetic simulations.
