Small Methods, EarlyView.We report a direct‐writing method for patterning silver‐enriched nanostructures with dual functionality: High electrical conductivity, with a resistivity of 95 µΩ·cm, and strong SERS activity, achieving enhancement factors exceeding 107. This approach enables an easy and cost‐effective alternative for the production of microstructures with applications

Advances in cholesterol and lipoproteins detection for healthcare: A review
VIEW, EarlyView.Cholesterol is one of the main biomarkers related to the development of cardiovascular diseases. Its detection still relies on traditional methods of analysis, such as gas and liquid chromatographies. Detection of free cholesterol in saliva with redox or enzymatic sensors or detection of lipoproteins in blood with aptamer sensors are currently the most

Exploring fluorescence and fragmentation of ions produced by electrospray ionization in ultrahigh vacuum [PDF]
, 2018 Fluorescence spectroscopy and mass spectrometry have been extensively used for characterization of biomaterials, but usually separately. An instrument combining fluorescence spectroscopy and Fourier-transform ion cyclotron resonance mass spectrometry ...

Unexpected Promotion of Bone Regeneration by Inhibition of BMPR1A‐Mediated BMP Signalling
Cell Proliferation, EarlyView.BMPR1A downregulation reduces ID1, releases TCF3 to activate GNG4‐PI3K‐AKT signalling, thereby promoting OPC proliferation and bone regeneration. ABSTRACT Bone morphogenetic protein (BMP) signalling plays a pivotal role in bone regeneration by regulating osteoprogenitor cell (OPC) function, and BMPs have been widely used in clinical treatment. However,

The Journal of Physiology, EarlyView.Abstract figure legend Calciprotein particles (CPPs) are small calcium‐ and phosphate‐containing nanoaggregates associated with the development of vascular disease (CVD) in chronic kidney disease (CKD). Previously, we have shown that CPPs induce endothelial cell (EC) dysfunction, possibly contributing to CVD in CKD, but the underlying molecular ...
