The origin of this research line is very recent and aims at meeting the increasing need to explore novel techniques that operate at the nanoscale and that are based on original ideas. It builds on existing expertise at the IMM in the field of instrumentation for nanotechnology - a synergic environment interfacing optics, nanomagnetism and semiconductor devices.
The objective of this subline is to design and develop new techniques and instrumentation addressed to perform fundamental and technological scientific research in the field of bio-organic intermolecular interactions and local probe techniques. Within this objective our purpose is to continue to expand our successful transfer of knowledge to industry with highly innovating quality instruments.
Our approach to biotransducers is based on the combination of the magnetic manipulation of biofuntionalized magnetic nanoparticles in suspension with the inexpensive, fast and relatively noise-insensitive optical detection. Two different approaches are explored - making use of light scattering and of light diffraction.
Within the local field techniques our activity is particulary focused on the investigation of high resolution, minimally perturbative and stable Atomic Force Microscopy operating modes and instruments for the acquisition of surface maps, particularly focused in liquid operating environments. Recently we have successfully tested and implemented a "magnetostrictive actuation" mode in a liquid cell.
