DNA-origami is a wonderful technique that enables the fabrications of all kinds of nanoscopic objects. We have been using them to build nanophotonic devices combining metallic nanoparticles to form optical antennas and single molecules. In our recent paper in Nano Letters, we demonstrate how optical nano-antennas self-assembled using DNA-origami can be used to direct the [...]
From August 1st until November 30th, Luciano is visiting the group of Prof. Philip Tinnefeld at the Faculty for Chemistry of the Ludwig-Maximilians-University of Munich (LMU), financed with a DAAD Scholarship. Luciano´s research stay is part of our standing cooperation with the group of Prof. Tinnefeld. He will help our german colleagues building their own [...]
From 5 to 7 June 2019, our national NANO meeting, the XIX Meeting on Surfaces and Nanostructured Materials, was held in Buenos Aires. Since 2001, this event brings together representatives from the academic, scientific and productive sectors to discuss the state of the art, challenges and advances in different areas of nanoscience and nanotechnology. This [...]
Students and young researchers from various disciplines working in the field of Bionanosciences gathered at the National University of San Martín (UNSAM) to share and discuss their projects, ideas, and perspectives. The meeting was organized by graduate and undergraduate students doing research at CIBION, the National University of San Martín (UNSAM), and the National Atomic [...]
Dr. Florian Steiner, postdoc in Prof. Tinnefeld's group at Ludwig-Maximilians-Universität München, visited our lab during the last month to learn about our new pulsed-interleaved MINFLUX set-up. During his stay, Florian (on the right; are those sunglasses??) worked closely with Ph.D. candidate Luciano Masullo (on the left, with proper laser safety goggles) who is in charge [...]
Today, Rodrigo Andrés Ponzio defended his doctoral thesis “Energy transfer in nanostructured organic materials” at the Physics Department of the Faculty of Exact and Natural Sciences, University of Buenos Aires, obtaining the highest honors. His thesis was carried out under the supervision of Dr. Fernando Stefani at CIBION and Dr. Rodrigo Palacios at the Institut of Energy research and [...]
Recently, silicon nanoparticles have raised interest in the plasmonics community they present size-dependent electric and magnetic resonances in the visible range. However, their widespread application has been limited (in comparison to metallic nanoparticles, for example) because their preparation on monodisperse colloids remains challenging. In our recent paper in ACS Photonics, we show that surfactant-free silicon [...]
We have been using DNA self-assembly for a while now. DNA-origami is a wonderful technique to build nanoscopic optical breadboards for our experiments. While DNA is highly versatile, it has the disadvantage of being fluffy... In fact, life uses proteins to build stuff, not DNA. So why not trying to direct protein self-assembly to build [...]
We are glad to welcome Dr. Marcelo Nollmann from the Center for Structural Biochemistry in Montpellier (CNRS/INSERM) as visiting Professor at the Physics Department of the University of Buenos Aires During his stay, Dr. Nollmann will give a course for graduate and undergraduate students of the Faculty of Exacts and Natural Sciences on "Molecular [...]
As part of our collaboration with the group of Prof. Stefan Maier, Dr. Mariano Barella travelled to London for a research stay at Imperial College. During his stay, Mariano will discuss and perform kick-off experiments for a new project with Dr. Julian Gargiulo, an ex-member of our lab currently working at Stefan Maier's lab. [...]
