Acting at the nanoscale to understand the macroscopic
The Nanosciences Department aims to access and operate at the nanoscale in order to target, detect, and understand the underlying mechanisms driving macroscopic responses.
To achieve this, it designs and develops nanomaterials capable of responding at the nanoscale to external stimuli (electrical, magnetic, optical, or chemical), as well as ultrasensitive nanosensors and nanometrology tools. These innovations are essential for addressing numerous societal challenges in health, the environment, and the agri-food sector.
The department brings together around twenty physicists and chemists and collaborates with industrial partners, non-academic organizations (CHU, CGFL, INRAE, INSERM), and numerous regional (FEMTO-ST, ICMUB, Institut Agro Dijon) and international academic partners in the USA, Japan, and Europe.
Highly interdisciplinary, the department possesses expertise in chemistry, physical chemistry, physics, biophysics, materials science, and numerical simulation.
It is organized around two strongly interconnected thematic axes:
– Development of functional nanomaterials
– Development of nanosensors and nanoscopy
Research topics
Development of functional nanomaterials
The department focuses its expertise primarily on the synthesis of nanomaterials for various applications.
These nanomaterials are divided into two main categories:
- Nanoparticles
- Superparamagnetic iron oxide nanoparticles (SPIONs)
- Micro/nano-carriers inspired by the properties of clay
Nanostructures
- Designed for photovoltaic applications
- Nano-sources and nano-assemblies dedicated to photonics and plasmonics
- 2D nanoporous membranes adapted for desalination
Development of nanosensors and nanoscale imaging
The department is also dedicated to the modeling and development of nanosensors and innovative nanometrology tools for various applications in the health, environmental, and food sectors:
Plasmonic and optical nanosensors
- Development of plasmo-photonic chips for health and agri-food applications
- Analysis of protein conformation
Fluidic nanosensors
- Study of the protein corona
- Protein sequencing
Multifrequency nanometrology tools
- Investigation of protein/biological membrane interactions
- Non-destructive techniques for component analysis
- Applications in pharmaceuticals
- Study of the assembly and remodeling processes of nucleoprotein complexes
