Utilizing single-molecule optical and AFM imaging and drive-spectroscopy tactics, we seek out to unravel the mechanistic aspects of the composition and dynamics of chromosomes. Our investigation interests involve:
You will help our writer matching method! In case you see any publications incorrectly attributed to this writer, remember to register and mark matches as suitable or incorrect.
[Laughs] ‘It absolutely was unquestionably a great hazard! At some time, I had been very well mindful that it could go Erroneous Which I could turn into a lot less effective, but I just ignored that. Curiosity has normally been my strongest driving pressure. And by chance it all labored out.’

That may be a dream of mine and we set to operate using a mouth watering dose of naivety. This really is something which will most likely yield stunning brings about the for a longer time expression, but that doesn't matter. You should not only want to operate over the concerns of tomorrow, but in addition over the concerns on the working day after tomorrow.’
Our investigate ranges within the biophysics of DNA to artificial cells and outside of. You should take a look under with the spectrum of our recent assignments.
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) within the nanopore. Simulations that terminated early on account of translocation with the rod through the pore are marked by a grey background.
Nanopores depict a chic and adaptable Device to evaluate single molecules. We study novel detection modes with reliable-point out nanopores and many ways to measure proteins with nanopores. Projects encompass the following:
The rotors harness Electricity from a nanoscale water and ion stream that is certainly generated by a static chemical or electrochemical potential gradient during the nanopore, that happen to be set up via a salt gradient or utilized voltage, respectively. These artificial nanoengines self-Arrange and operate autonomously in physiological disorders, suggesting solutions to constructing energy-transducing motors at nanoscale interfaces.
1). The existing–voltage curves showed sizeable modulations with gate voltage, even at area temperature, which was in line with band bending in a very ~0.6 eV bandgap semiconducting nanotube. These facts also showed the conductance could be modulated by six orders of magnitude by switching the gate voltage. The outcome of the function — a place-temperature transistor produced from one carbon nanotube molecule — were revealed in Mother nature in Could 1998.
[14] In 2005 Dekker turned involved in Netherlands-huge discussions about Smart Design and style, a motion that he has given that Evidently distanced himself from. Dekker advocates that science and religion will not be in opposition but can be harmonized.
Meanwhile, to be sure continued assist, we cees dekker are displaying the site with no designs and JavaScript.
2008, 1st observation of protein-coated DNA translocation by means of nanopores; resolved the origin of the electrophoretic drive on DNA in nanopores; uncovered a major velocity improve of microtubules in electric fields; found out an anomalous electro-hydrodynamic orientation of microtubules; and solved the origin of noise in carbon nanotubes in liquid
2004, discovery of new physics in translocation of DNA as a result of nanopores; 1st experimental study of ions conduction in nanofluidic channels; initially electrochemistry with person one-wall carbon nanotubes; STM detection and control of phonons in carbon nanotubes; to start with electrical docking of microtubules on kinesin-coated nanostructures; very first biophysics characterization on the mechanical Qualities of double-stranded RNA; and to start with solitary-molecule analyze of DNA translocation by a restriction-modification enzyme.
