Prof. Jochen Feldmann has been a great scientist and mentor for many younger researchers. On the occasion of his 60th birthday, several of his mentorees and collaborators have contributed to a special issue of Advances Optical Materials in his honor. Happy birthday Jochen!!! Advanced Optical Materiales - Special Issue Photonics and Optoelectronics of [...]
During two weeks of June, Prof. Stefani visited our close collaborator Prof. Guillermo Acuna at the University of Fribourg, Switzerland, where several former members of our group are currently working, like Dr. Mariano Barella and Ph.D. candidate Germán Chiarelli. Prof. Stefani gave lectures on the recent advances of our lab, and supervised projects in [...]
Fluorescence microscopy is a major workhorse in life sciences, biophysics, and physical chemistry, as it allows visualization with great specificity and sensitivity. In particular, the detection of single fluorescent molecules has been used to provide information beyond ensemble averages with applications in different fields of research. For example, super-resolution methods based on the localization of [...]
The morphology and composition of metallic nanoparticles (NPs) determine their optical response, so finely controlling them at the single particle level is a key to achieve tailored functionalities. In a recent publication by Luciana Martinez et al. we show that the plasmon-driven growth of Au NPs can be monitored in real time through photoluminescence measurements. [...]
Today, Cecilia "Chechu" Zaza defended her Ph. D. thesis “Impresión óptica de nanopartículas de silicio y métodos para medir temperatura con resolución espacial en la nanoescala”, obtaining the highest grade from the jury Dr. Gustavo Grinblat, Dr. Ana Sol Peinetti, and Dr. Ana María Huergo. Chechu joined the group in 2017 to work on her [...]
Starting in March 2022, Dr. Piotr Zdankowski has joined our group for a postdoctoral stay with a Research Fellowship of the National Agency for Scientific Exchange of Poland. The Research Fellowship programme aims to implement the Projects together with eminent foreign scientists and scientific teams as well as establish long-term relationship with foreign scientific teams. [...]
Founding Director of CIBION Prof. Dr. Pedro Aramendía has retired after 10 years leading the activities of the institute. Pedro has been a great researcher, teacher, and mentor of many young researchers. Thank you Pedro for all your work and [...]
MINFLUX represented a breakthrough showing that single fluorescent molecules could be localized with 1-2 nm precision with moderate photon counts.Such level of localization efficiency enables single-molecule tracking and super-resolution imaging with true molecular resolution. The key concept was to estimate the molecular position from a sequence of exposures to spatially displaced a light minimum. Expanding [...]
Prof. Fernando Stefani has been appointed to the Editorial Advisory Board of ACSPhotonics, becoming the only member from Latin America. ACS Photonics is a reference journal in the field of photonics, and has recently updated the list of topics covered under the new Editor in Chief Prof. Romain Quidant: Nanophotonics, including plasmonics and polaritonics, optical [...]
Focused optical fields are key to a multitude of applications involving light-matter interactions, such as optical microscopy, single-molecule spectroscopy, optical tweezers, lithography, or quantum coherent control. A detailed vectorial characterization of the focused optical fields that includes a description beyond the paraxial approximation is key to optimize technological performance as well as for the design [...]
