NANOSCALE goes material sciences!
To speed up the innovation cycle and to open new applications in the field of light-matter interactions and surface chemistry, SAF microscopy has been established in the Salomon lab in the Chemistry Department of Bar-Ilan University at the BINA Nanocenter. Check out www.lab-salomon.com for research projects and available positions!
NANOSCALE reaches out for early science education. We warmly welcome Julie CALMEL for a voluntary internship.
My name is Julie and I’m a student in the 1 st year of high school. At sixteen, I’m very happy to do an internship within SPPIN’s research teams. Last year, I had the chance to discover the research world last year, in physics and biology laboratories of the Ecole Normale Supérieure (Paris). I really enjoyed my first experience, for this reason I’m taking the opportunity to improve my knowledge and develop team spirit in SPPIN’s team. Therefore I’m very exiting to take part in a science research project during a month that will be an extremley enriching experience for me.

Carine Julien will rejoin the NANOSCALE team from 5 April. She is an assistant professor in chemical physics currently affiliated with the Ecole Normale Supérieure (ENS Paris Saclay). Carine will be working on advanced aspects of super-critical angle fluorescence microscopy as well as supercritical-angle Raman imaging.
“Initially trained as a chemist, I’ve always been interested in the spectroscopic signals one may obtain after a physical stimulus of the matter, and particularly by an optical stimulus. I specialized in fluorescence and Raman spectroscopies and microscopies, empowering them at the nanoscale, i.e. at the single nano-object level. One of the main aims of this research is to increase the spatial resolution beyond the diffraction limit. Indeed, single molecules can be used as sensors of their local environment and provide a better insight by avoiding ensemble averaging characteristic for macroscopic measurements.
To be able to run such studies with weak Raman signals- their drawback is to be a quite inefficient process- I used enhancement strategies offered by a plasmonic substrate that give rise to SERS, i.e. Surface enhanced Raman Scattering.I find it very interesting not only to use the spectroscopy to study the sample, but also -by working a thet single-molecule level- to investigate the mechanism of this enhancement; the latter being assumed to have 2 components: a well-established electromagnetic field enhancement and a « chemical effect », responsible for the selectivity of the enhancement.
Concerning Fluorescence, I’ve been working on different configurations from widefield to confocal, and exploited the spectroscopic signal both at the steady state and time resolved (lifetime) for numerous kinds of samples, from organic molecules and fluorophores, inorganic samples such as Qdots, or hybrid materials for photovoltaic devices. I find it very interesting to discover new material and try to understand their specificities and the way optical signal can help in the understanding of the structures and interactions at stake.
I’m very happy to join SPPIN’s Nanoscale team to exploit even more such spectroscopic signal, at the Fourier plane, and after experiencing a very wide field of chemical samples, discover and understand biological samples and processes by optical means. This is both challenging and exciting for me.”
The entire NANOSCALE project team extends a very warm welcome to Carine.

We welcome Natalia Mañas–Chavernas as a new Master student in quantitative Fourier-plane imaging
My name is Natalia and I am studying biomedical engineering with the BME Paris Master Program. My research interests are on image treatment and data analysis using machine learning, which is why I plan to specialize next year in Bioimaging.Although I have some experience from internships I made at hospitals and at a start-up, I would like to learn more about how research is performed in a lab, as I aim for a career in research. Regarding my skills, I am most comfortable programing in Python, Java and Matlab. I did my Bachelor on classification algorithm development using machine learning and, throughout my degree, I have worked on several projects on image enhancement and segmentation techniques.I consider myself a passionate, hard-working and proactive person who can learn quickly and adapt. Furthermore, I have a strong sense of responsibility, of effort and rigor. I hope to be a great asset to the NANOSCALE team and I believe this experience to be extremely enriching for me. Thank you for having responded positively to my application.
