Dear all, There is a FILM Seminar today in SAF, G120 at 12.30 by Dr Valentina Caorsi, from Abbelight: See details below. All the best and hope to see you there!

Different approaches have been proposed from structured illumination microscopy (SIM) to stimulated emission depletion (STED) and single molecule localization microscopy approaches (SMLM). SMLMs, such as fluorescence photoactivated localization microscopy ((F)PALM) and direct stochastic optical reconstruction microscopy (dSTORM), can easily provide lateral localization precision down to 5–10 nm. However, 3D multicolour nanoscopy is still a challenge and a lot of effort has been made by the nano-community to develop quantitative and reproducible 3D super-localization methods. In this panorama abbelight developed a new nanoscope allowing precise isotropic 3D localization precision (15X15X15nm) by decoupling the lateral and axial detection. For the latter, two different sources of axial information are retained: the supercritical angle fluorescence (SAF) that provides an absolute z-reference (0-600nm) and a strong astigmatism-based PSF measurement allowing an extended axial depth (up to 5•m). Thus, nanoscopy can be accessible, to gain more details in 3D and extract quantitative information (numbers, size, distributions, spatial organization of individual molecules, clusters or organelles). Additionally, abbelight is organising a 3-days workshop on SMLM at King’s College London (see attached poster), and there are spaces for Imperial College researchers to attend and test abbelight’s DAISY module with their own samples.
