Nanotechnology gives A selection of alternatives to contribute to biology. Right here I will current illustrations wherever nanofabrication – a chance to make confined structures with dimensions at will – is used to examine the biophysics of single molecules and cells. I will present some examples from our lab:

Nanofabrication of electrodes with sub-five nm spacing for transport experiments on one molecules and metal clusters
De sterke polarisatie in de discussie rond schepping/evolutie en meer algemeen rond geloof/wetenschap lijkt helaas geen eind te kennen. Toch is er wel degelijk een heilzame middenweg, maar deze krijgt in excess of het algemeen weinig aandacht. Dit boek kan hier wellicht verandering in brengen. Wie de geschiedenis van de relatie tussen geloof en wetenschap in duikt, komt tot verrassende inzichten. De moderne mens leeft satisfied veel stereotypen die historisch niet verantwoord blijken te zijn. Afgezaagde typeringen als ‘Vroeger dachten we dat de
Inside the many years subsequent these discoveries, my research pursuits shifted to biophysics and nanobiology, And that i became much less involved in the event of nanotube electronics. The main focus of many scientists in the sphere also shifted to graphene (the place, funnily adequate, the very first graphene ribbons were described as ‘nanotubes which have been Slice open along their duration’) soon after the discovery of The 2-dimensional content in 2004.
We condition microorganisms into forms that deviate from their natural phenotype. Especially, I'll demonstrate our capability to shape Dwell E. coli microbes into novel shapes like rectangles, squares, triangles and circles.
2000, discovery that nanotubes can carry incredible big latest densities; resolved the controversial situation of Digital transportation ceesdekker by means of DNA molecules by measurements of insulating habits at the single molecule degree; and demonstration of the AFM system for single-molecule manipulation of nanotubes
In 1993, to be a young and eager associate professor at Delft College of Technology, I had originally concentrated the research attempts of my group on measuring the electrical conductance of one conducting-polymer molecule. In just two years, we had designed a tool wherein a single wire of a phthalocyaninepolysiloxane polymer was connected among two carefully spaced steel nanoelectrodes.
But carbon nanotubes have remained a exploration matter of significant curiosity to several. Certainly, the outlook on utilizing carbon nanotubes to construct useful gadgets, in areas such as radio-frequency electronics, electronic electronics and versatile electronics, remains bright.
Case in point (four) of bending configurations in 3D simulations of DNA rods on nanopores. A part of the membrane is shown in gray, the rim with the pore is highlighted in crimson, along with a 3D rendering of the movement on the DNA rod is displayed.
Cees Dekker is Distinguished College Professor at TU Delft. Properly trained to be a physicist, he pioneered nanotechnology with many discoveries on carbon nanotubes in the nineteen nineties. Considering the fact that 2000, he moved to one-molecule biophysics and nanobiology. His present-day exploration concentrates on (i) nanopores for protein sequencing; (ii) chromosome construction, particularly SMC motor protein; and (iii) building a living artificial mobile from lifeless molecules. Dekker is undoubtedly an elected member in the KNAW and fellow on the APS as well as the IOP.

Dekker heeft fundamentele ontdekkingen gedaan op het gebied van koolstof nanobuisjes. Mede vanwege deze werkzaamheden is hij al jaren de meest geciteerde fysicus in Nederland. Tegenwoordig onderzoekt hij achieved enkel-molecuultechnieken de biofysica van moleculen in de biologische cel. Dekker is naast zijn wetenschappelijk werk ook bekend vanwege zijn belangstelling voor de relatie tussen geloof en wetenschap en de discussie rond clever style in 2005. (nl)
