Field-effect nano-biosensors (or Biofets, biologically sensitive field-effect transistors) have recently been demonstrated experimentally and have thus gained interest as a technology for direct, label-free, real-time, and highly sensitive detection of biomolecules. The experiments have not been accompanied by a quantitative understanding of the underlying detection mechanism. The modeling of f...

Na ion batteries (NIBs) are considered as a promising low cost and sustainable energy storage technology. To better design nanoporous carbons as anode materials for NIBs, molecular dynamics simulations have been employed to study the behavior of Na+ ions (as well as PF6- ions) confined within carbon nanopores, in the presence of non-aqueous (organic) solvent. The effects of pore size and surfac...

It has been suggested that decreases in red cell surface-charge density accompany aging in vivo and reflect alterations in the cell surface which play a critical role in the recognition and elimination of effete erythrocytes by macrophages in the reticuloendothelial system. The bases for this suggestion are reports that the surfacecharge density progressively decreases for red cell subpopulatio...
