European Journal of Neuroscience, Volume 56, Issue 12, Page 6141-6161, December 2022., 2022 Chemical synapses are tiny and overcrowded environments enriched with thousands of protein species. Many efforts have been devoted to developing sensors and actuators able to evaluate and control synaptic communication. Most of these recent tools are based on the engineering of one or more specific synaptic proteins used to target active moieties to ...

Single molecule mass photometry of nucleic acids
bioRxiv, 2020 Mass photometry is a recently developed methodology capable of detection, imaging and mass measurement of individual proteins under solution conditions. Here, we show that this approach is equally applicable to nucleic acids, enabling their facile, rapid

Overview of Gaia Multi-Color Photometry
Open Astronomy, 2003 Gaia will obtain multi-color photometry for astrometric and astrophysical purposes. A photometry in five broad bands and with high angular resolution will be obtained after every astrometric observation of a star, especially for the sake of correcting ...

The Apparent Tidal Decay of WASP-4 b Can Be Explained by the Rømer Effect
Universe, 2023 Tidal orbital decay plays a vital role in the evolution of hot Jupiter systems. As of now, this has only been observationally confirmed for the WASP-12 system.
