On the active site of mononuclear B1 metallo beta-lactamases: a computational study

Matteo Dal Peraro, Paolo Carloni

Metallo-beta-lactamases (M beta Ls) are Zn(II)-based bacterial enzymes that hydrolyze beta-lactam antibiotics, hampering their beneficial effects. In the most relevant subclass (B1), X-ray crystallography studies on the enzyme from point to either two zinc ...

Ultrasensititve system for the real time detection of H2O2 based on strong coupling in a bio-plasmonic system

Olivier Martin, Christian Santschi, Shourya Dutta Gupta

We theoretically investigate the dependence of the different parameters of an optical biosensor for the detection of Hydrogen peroxide (H2O2) based on absorption enhancement of Cytochrome c molecules near gold nanoparticles. H2O2 is a major reactive oxygen ...

Surface Impurities Are Not Responsible For the Charge on the Oil/Water Interface: A Comment

Sylvie Roke, Rüdiger Scheu, Kailash Chandra Jena

A recent communication by Roger and Cabane[1] on the origin of negative charge on the interface between oil and water states that: "The basic assumption of all previous experimental and theoretical studies has been that these systems have "pristine" oil/wa ...

Uranium and manganese assembled in a wheel-shaped nanoscale single-molecule magnet with high spin-reversal barrier

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

Discrete molecular compounds that exhibit both magnetization hysteresis and slow magnetic relaxation below a characteristic 'blocking' temperature are known as single-molecule magnets. These are promising for applications including memory devices and quant ...
