Prof. Stefan Hell invited Prof. Stefani to give a lecture at the Max Planck Institute for Multidisciplinary Sciences on the latest advances on super-resolution microscopy with sub-10 nm resolution. This was the first meeting in person after the COVID-19 pandemic with long term collaborators and mentors of Prof Stefani, Prof. Stefan Hell [...]
Prof. Stefani was invited by Prof. Joerg Enderlein to a give a coloquium at the University of Göttingen and discuss future collaborations with his group. He also maintained promissing disscussions with Prof. Silvio Rizzoli and group leader Dr. Felipe Opazo. Thank you Joerg for the great time!
Several super-resolution methods make use of toroidal foci, i.e. light foci with a central minimum, ideally a zero, of intensity. For example, STED microscopy uses toroidal foci to suppress fluorescence emission in the periphery of the excitation focus through stimulated emission. Also, interrogating molecular position using a minimum of intensity is the basis for the [...]
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 :-)
