Micro-sized hair-like structures, such as cilia, are abundant in nature and have various functionalities. Many efforts have been made to mimic the fluid pumping function of cilia, but most of the fabrication processes of these “artificial cilia” are tedious and expensive, hindering their ...

Abstract Nowadays, mass spectrometry‐based proteomics is carried out primarily in a bottom‐up fashion, with peptides obtained after proteolytic digest of a whole proteome lysate as the primary analytes instead of the proteins themselves. This experimental setup crucially relies on a ...

Abstract We describe a new electrochemical biosensor based on estrogen receptor α (ER‐α) for label‐free detection of 17β‐estradiol, a model of endocrine‐disrupting compounds. ER‐α is coupled onto the gold electrode through its 6‐His tag and NTA‐copper complex. After interaction of ...

We used scanning white light interferometry to view the craters produced during secondary ion mass spectrometry (SIMS) analysis of the CaCO3 skeleton of an aragonitic coral. The dimensions and volumes of craters sputtered during trace element, δ18O, δ13C and δ11B analyses were determined. ...

The interactions of IgG Fc region with Fc receptors are optimized by the tailoring of a single conserved N‐linked glycosylation site at Asn‐297. Our previous study has demonstrated that the age‐related Fc‐glycosylation change is featured by sex specificity and that the Fc‐glycosylation has ...
