Dr. Ianina Violi has been elected to join the National Scientific and Technical Research Council (CONICET) as Assistant Researcher, directed by Dr. Galo Soler Illia and co-directed by Prof. Fernando D. Stefani. On a very competitive contest, Ianina was one of the 17 new researchers selected to join CONICET in Chemistry. In her new role, [...]
Every year, Physics World, the world's leading physics magazine published by the Institute of Physics, selects the 10 major contributions made for the advancement of Physics. We are proud and happy to see that MINFLUX has been included in this short list: 2017 top-ten achievements in Physics according to the Institute of Physics MINFLUX [...]
After the success of the first meeting, CIBION hosted the 2nd Metting of Young Researchers in Optics and Photophysics sponsored by the Optical Society of America through its Student Chapter. Again, it was a great success. Congratulations to the local organizers and all participants. We look forward to the next meeting!
Fluorescence nanoscopy is enabling the visualization and discovery of periodic protein structures in their natural environment. Remarkable examples are the nuclear pore complex or the membrane-associated periodic cytoskeleton of neurons (MPS). The MPS of neurons can be visualized by fluorescence nanoscopy (e.g. STED) but is invisible using conventional microscopy (e.g. confocal) The next step [...]
Es importante que los miembros de la comunidad científica y sus socios industriales conozcan la evolución de la inversión pública en el sistema científico-tecnológico. El proyecto de ley de presupuesto enviado por el Poder Ejecutivo Nacional (PEN) plantea una nueva reducción de la inversión pública en ciencia y técnica. Para 2018 se propone una reducción [...]
On friday 20th of October, friends and colleagues of Prof. Dr. Niek van Hulst came together from around the globe, to celebrate his 60th birthday discussing some of Niek´s favorite topics in Nanophotonics: Manipulation and control of molecular beams Precision spectroscopy of molecular hydrogen and the search for new physics Light twists at the nanoscale [...]
Our close collaborator Dr. Guillermo Acuna from the Technical University of Braunschweig (Germany) was in Buenos Aires, from September 5th to October 7th, as visiting professor of the Faculty of Exact and Natural Sciences of the University of Buenos Aires. Dr. Guillermo Acuna giving a lecture at the Physics Department of FCEN-UBA During his stay, [...]
The optical manipulation team of our lab was recognized with the Innovar Award 2017 for the method of automated optical printing of colloidal nanoparticles. Congratulations to Santiago Cerrotta, Germán Chiarelli, Cecilia Zaza, Ianina Violi! Of course, also to Julián Gargiulo, who is not in the photo because he is at Imperial College London. Our [...]
Optical printing is a wonderful tool to fabricate arrays of colloidal nanoparticles on solid substrates. However, when a nanoparticle absorbs light, it heats up and generates very large temperature gradients. In turn, those temperature gradients produce thermo-phoretic and thermo-osmotic forces that are strong enough to disturb the optical manipulation of nanoparticles at close separation distances. [...]
Optical printing is a wonderful tool to capture colloidal nanoparticles from suspension and place them on specific positions of a substrate. Still, the mechanistic details of the processes involved are complex and not fully understood. In our recent publication in ACS Nano, we provide new insight into the mechanism of optical printing colloidal nanoparticles and [...]
