Determination of Trace Mercury in Rocks by Dual-channel Atomic Fluorescence Spectrometry and Solid Sampling-Cold Atomic Absorption Spectrometry

Yankuang ceshi, 2021
BACKGROUND The detection of trace mercury in rocks typically provides biased and non-reliable results because of the complex internal unit cell structure, incomplete hot water bath acid hydrolysis extraction, volatilization loss, and contact pollution ...

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

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 ...
