Focus image scanning microscopy for sharp and gentle super-resolved microscopy
Nature Communications, 2022 Super-resolution microscopy techniques can be challenging for live cells and thick samples. Here, the authors propose a method to reduce beam intensity and remove out-of-focus fluorescence background in image-scanning microscopy (ISM) and its combination

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Highly Efficient Trityl-nitroxide Biradicals for Biomolecular High-field Dynamic Nuclear Polarization [PDF]
, 2021 Dynamic nuclear polarization (DNP) is a powerful method to enhance the sensitivity of solid-state magnetic nuclear resonance (ssNMR) spectroscopy. However, its biomolecular applications at high magnetic fields (preferably > 14 T) have so far been limited

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Gas Temperature Measurement Using Differential Optical Absorption Spectroscopy (DOAS)
, 2018 A nonintrusive method for flow gas temperature measurement using differential optical absorption spectroscopy (DOAS) was demonstrated. A temperature-dependent spectra (TDS) originated from the DOAS spectra of sulfur dioxide (SO2) in the wavelength range ...

A compact two-wave dichrometer of an optical biosensor analytical system for medicine
EPJ Web of Conferences, 2017 An experimental model has been developed of a compact two-wave dichrometer on the base of LEDs that is well-suited to work with “liquid” DNA nanoconstructions as biosensing units.
