2016 IEEE 13th International Symposium on Biomedical Imaging (ISBI), 2016 We introduce the concept of "Ultrasound Spectroscopy". The premise of ultrasound spectroscopy is that by acquiring ultrasound RF data at multiple power and frequency settings, a rich set of features can be extracted from that RF data and used to characterize the underlying tissues.

Pushing the performance of image scanning microscopy to its limits with maximum likelihood reconstruction [PDF]
EPJ Web of Conferences, 2023 Fast and sensitive detector arrays make Image Scanning Microscopy (ISM) the natural successor of confocal microscopy. Indeed, ISM enables super-resolution at an excellent signal-to-noise ratio. Optimizing photon collection requires large detectors and so

Distance-Dependent Plasmon-Enhanced Fluorescence of Submonolayer Rhodamine 6G by Gold Nanoparticles
Nanoscale Research Letters, 2021 We investigate the fluorescence from submonolayer rhodamine 6G molecules near gold nanoparticles (NPs) at a well-controlled poly (methyl methacrylate) (PMMA) interval thickness from 1.5 to 21 nm.

Solid-state NMR spectroscopy on complex biomolecules [PDF]
, 2010 Biomolecular applications of NMR spectroscopy are often merely associated with soluble molecules or magnetic resonance imaging. However, since the late 1970s, solid-state NMR (ssNMR) spectroscopy has demonstrated its ability to provide atomic-level ...
