‘Indeed, that may be about proper. I try to find a physical idea of biological programs inside of a bottom-up way. I feel you could potentially distinguish three traces of investigate in my group at this time. The very first worries chromosome composition: how do you get yourself a metre-very long DNA polymer folded and organised in this kind of microscopic cell? We now have formulated visualisation techniques that enable us to review how, such as, SMC proteins loop DNA (video on Youtube) as a way to Create up chromosomes.
Reconstitution of ultrawide DNA origami pores in liposomes for transmembrane transportation of macromolecules
, Groningen scientists existing the effects in their endeavours to make labs a lot more sustainable and supply tricks for other labs.
Our get the job done was immediately adopted up by Many others, most notably by Phaedon Avouris and colleagues at IBM, who in Oct 1998 posted their conclusions on transistors comprised of one- and multi-walled carbon nanotubes in Used Physics Letters.
This yielded a breakthrough. Within just a few months, we were in the position to measure transportation via somebody single-walled carbon nanotube. Based upon minimal-temperature experiments by a superb PhD pupil in my team, Sander Tans (now a valued colleague and professor at Delft University of Know-how with the Energetic research lab at AMOLF in Amsterdam), we confirmed that carbon nanotubes had been authentic quantum wires with very very long (micrometres) electronic coherence lengths — confirming theoretical predictions of metallic behaviour.
Electrical transportation in monolayers of phthalocyanine molecular wires and AFM imaging of a single wire bridging two electrodes
All parameters were exactly the same for each panel In this particular movie, aside from the Original placement of the 6hb rod (shown in blue) around the nanopore. Simulations that terminated early as a result of translocation on the rod from the pore are marked by a gray history.
2011, 1st in vitro measurements of transport throughout an individual biomimetic nuclear pore complicated; enhancement of multiplexed magnetic tweezers for kilo-molecule experiments; and solved the mechanism of homology recognition in DNA homologous recombination
You can help our author matching process! When you observe any publications incorrectly attributed to this creator, you should register and mark matches as right or incorrect.
There was just one challenge however — we did not observe any measurable electrical conduction from The one polymer molecules. We concluded that at The one-molecule stage, conducting polymers had been really not this sort of excellent conductors, which was instead disappointing. We thus broadened our perspective to try to search out additional promising molecules.
Example (four) of bending configurations in 3D simulations of DNA rods on nanopores. A portion of the membrane is revealed in gray, the rim from the pore is highlighted in pink, as well as a 3D rendering of the movement of the DNA rod is shown.
Cees Dekker is Distinguished College Professor at TU Delft. Qualified like a physicist, he pioneered nanotechnology with numerous discoveries on carbon nanotubes in the nineteen nineties. Due to the fact 2000, he moved to solitary-molecule biophysics and nanobiology. His present research concentrates on (i) nanopores for protein sequencing; (ii) chromosome construction, in particular SMC motor protein; and (iii) developing a residing synthetic mobile from lifeless molecules. Dekker is surely an elected member from the KNAW and fellow to the APS as well as IOP.
