Field-Dependent DNA Mobility in 20 nm High Nanoslits
Field-dependant DNA mobility in nanoslits was investigated in a cooperation between scientists of two Nano2Life members at the University in Twente (NL) and the university of Lund (SE). The results led to the conclusion that the classical interpretation of the transport behaviour of DNA under higher fields with the viscous friction models needs to be modified when taking these new results into account.

Endothelial Cells as Salt Sensors
Ingestion of large amounts of salt in the diet has been associated with increased blood pressure and harmful cardiovascular effects, but precisely how salt influences blood pressure is not clear. Oberleithner et al. describe experiments showing a direct effect of sodium on the physical stiffness of endothelial cells. The results indicate to a possible cause of the deleterious effects of hypertension. [more] |

Nanobiotechnology of Biomimetic Membranes
Nanobiotechnology of Biomimetic Membranes describes the current state of research and development in biomimetic membranes for nanobiotechnology applications. The application areas in nanobiotechnology range from novel nanosensors, to novel methods for sorting and delivering bio-active moleculres, to novel drug-delivery systems. The success of these applications relies on a good understanding of the interaction and incorporation of macromoleculres in membranes and the funamental properties of the membrane itself. [more] |

Mutant Chaperonin Proteins: New Tools for Nanotechnology
Is Nanobiotechnology new, true and important? Jonathan Trent from the NASA Ames Research Center and his co-workers show how nanotechnology could develop continued economic prosperity, global energy needs, and national security issues. They have been studying "heat shock protein 60" (HSP60) in organisms living at high temperatures, the so-called "thermophiles." Their work is focused on using nanbiotech methods to create enzyme arrays for biofuels production. [more] |

A carbon Nanofibre Scanning Probe Assembled Using an Electrothermal Microgripper
A group of researchers from the Technical University of Denmark (DTU) and University of Oldenburg (UO) have now shown "pick-and-place" assembly of a working device using a silicon gripper - a robotic "hand” some 10000 times smaller than a human hand. They managed to break off a sturdy carbon nanofibre, and position it at the pyramidal tip of an atomic force cantilever. [more] |
