Center for Bionanoscience Research (CIBION), National Scientific and Technical Research Council (CONICET)
Physics Department, Faculty of Exact and Natural Sciences, University of Buenos Aires (UBA)
Using optical methods, we explore the properties and technological applications of nanoparticles, single molecules, nanostructured materials, supramolecular assemblies, biological and hybrid nanosystems.
The Applied nanoPhysics Group was launched in October 2009 at the Physics Department, Faculty of Exact and Natural Sciences, of the University of Buenos Aires (UBA)
In 2012 we moved our labs to the Center for Bionanoscience Research (CIBION) of the National Scientific and Technical Research Council (CONICET), while Prof. Stefani still holds his position at the Physics Department of the University of Buenos Aires.
CURRENT RESEARCH ACTIVITIES
Fluorescence nanoscopy.
Super-resolution fluorescence microscopy, also known as fluorescence nanoscopy, has revolutionized biological imaging because they provide deep sub-wavelenght spatial resolution while keeping the low-invasiveness of far-field optical interrogation. We apply and optimize well-established methods like STED and STORM, and develop new ones, such as MINFLUX, and open-source software for fluorescence nanoscopy. With them, we address questions of cellular and neuronal biology.
Optical printing colloidal nanoparticles.
Colloidal chemistry enables the fabrication of nanoparticles of different shapes, sizes and material compositions, that exhibit unique physical and chemical properties, inexistent in bulk materials. In order to make use of those properties in devices and circuits, it is necessary to develope methods to bring the colloidal nanoparticles from the liquid phase to specific locations of solid substrates. We address this challenge using optical forces.
Self-assembled Nanophotonic Devices.
Semiconductor-based devices are approaching intrinsic limits of speed and heat dissipation.
Optical devices are faster and practically loss-less, but their size miniaturization is limited by the wavelength of light. Nanophotonics and Plasmonics deals with the manipulation of light at the nanoscale. We investigate light-matter interaction between single-photon emitters and metallic nanoparticles organized in nanodevices by self-assembly.
