Prof. Stefani was invited to the ETH Zurich to give a lecture to graduate and undergraduate students, and visit the labs of world experts on nanophotonics Prof. Lukas Novotny and Prof. Romain Quidant. Thank you Romain and Lukas for the great time and discussions, as always.
Obtaining arrays of single nanoparticles with three-dimensional complex shapes is of interest for many applications, but remains an open challenge of nanotechnology. Current nanolithographic methods do not allow for the preparation of nanoparticles with complex features like nanostars. In our recent paper in Nano Letters, we present an investigation of the optical printing of gold [...]
We received Prof. Joerg Enderlein from the University of Goettingen at CIBION to show him our labs and discuss current status and future trends of our many common interests, like single-molecule spectroscopy and super-resolution microscopy. Prof. Enderlein is a world expert on single-molecule detection, electromagnetic manipulation of fluorescence states, and super-resolution microscopy [...]
Ph.D. candidate Florencia Choque and Prof. Stefani participated in the 11th International Weber Symposium on Innovative Fluorescence Methodologies in Biochemistry and Medicine held in Punta del Este, Uruguay, on January 8-13, 2023. The "Weber Symposium" honors the fundamental and far-reaching contributions of Professor Gregorio Weber. It provides an overview of modern fluorescence methodologies and applications [...]
To honour the effort and great performance of our football national team, Luciana Martínez used our optical printing setup to make a "nano FIFA world cup" made of gold nanoparticles. The FIFA world cup is made of about 6 kilograms of gold 18k, which is about 4,5 kilograms of pure gold. The nano world [...]
Friends, students, colleagues and collaborators of Pedro Aramendía got together at the Faculty of Natural and Exact Sciences of the University of Buenos Aires to celebrate his career and say thanks for so many years of great work and company. Pedro was the founding Director of CIBION and was in charge until early 2022. [...]
Nothing else to say... like every year we had our yearly get together of the whole institute, and it was great fun :-)
Ph. D. candidate Luciana Martínez gave a talk at the 4th edition of JOBION held at the Centro Cultural de la Ciencia, in Buenos Aires. Luciana presented her research on the challenges of optical printing metallic nanoparticles of complex shape, particularly gold nanostars. JOBION is a self-organized regular meeting where young researchers working [...]
Localization of single fluorescent emitters is central for many physicochemical and biophysical measurements at the nanoscale and beyond ensemble averaging. Examples include single-molecule tracking and super-resolution imaging by single-molecule localization microscopy. Among the numerous localization methods available, MINFLUX constituted a breakthrough for achieving a ∼10-fold improvement in resolution over wide-field camera-based approaches, reaching the [...]
This year, the annual meeting of the SAB was held in Rosario. CIBION contributed with the folowing presentations: Gonzalo Escalante - "Super-resolution of membrane proteins in Trypanosoma cruzi" Santiago Sosa - "Determining the orientation of single molecules in a protein cage by fluorescence nanoscopy" Luis Marcano-García - "Determination of association equilibrium constant from single [...]
