Coherence‐Gated Mirau Interferometry for Single‐Shot Quantitative Phase Imaging and Motion Sensing

open access: yesLaser &Photonics Reviews, EarlyView.
This paper presents a compact add‐on module converting a Mirau or other on‐axis interferometer into a single‐shot quantitative phase imaging system using coherence gating and precise optical path matching. Demonstrations include time‐resolved imaging of human cells and streaming red blood cells, visualization of evaporation dynamics in liquid mixtures,

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

Comparison of In‐Gel and SP3 Based Sample Preparation Protocols for LC‐MS/MS Based Proteomics

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Sensitivity, robustness, and reproducibility of sample preparation are main determinants of data quality in bottom‐up mass spectrometry‐based proteomics. To this end, in‐gel protein clean‐up and digestion has been used for decades and is characterized by its robustness and compatibility with harsh lysis conditions.
