‘Sure, that is definitely about correct. I seek for a physical knowledge of Organic systems in the base-up way. I think you could possibly distinguish three lines of investigation in my team in the meanwhile. The first considerations chromosome framework: how do you obtain a metre-long DNA polymer folded and organised in this type of microscopic cell? We have now created visualisation tactics that make it possible for us to check how, one example is, SMC proteins loop DNA (online video on Youtube) to be able to Construct up chromosomes.
Our group research bacterial mobile division which is aiming to constitute a ‘bottom up biology’ in artificial cells that could autonomously divide. Our principal curiosity lies in mobile division, chromatin framework, and spatial Handle.
The following articles or blog posts are merged in Scholar. Their put together citations are counted just for the very first post.
Considering the fact that 2000, Dekker has shifted the key concentration of his function in direction of biophysics where by he research the Houses of one biomolecules and cells using the resources of nanotechnology. This modification of industry was driven by his fascination for your amazing performing of biological molecular structures, along with because of the lengthy-phrase point of view a large number of interesting discoveries may be anticipated In this particular subject.[five] Present-day strains of research in his biophysics group are inside the regions of:[6]
To browse Academia.edu and the wider Online a lot quicker and much more securely, remember to have a couple seconds to improve your browser.
Microbiology has only existed for a century, because we started to examine micro-organisms far more severely. I assumed nanobiology was an appropriate term, simply because all molecular biological pertinent interactions happen with the nanoscale: a protein is a number of nanometres in dimensions, DNA is two nm thick.’
All parameters were being the same for each panel On this movie, apart from the First placement of your 6hb rod (shown in blue) around the nanopore. Simulations that terminated early as a result of translocation on the rod through the pore are marked by a grey background.
Studying DNA loop extrusion by SMC proteins for chromosome architecture with single-molecule assays.
The rotors harness Electrical power from the nanoscale water and ion move that is definitely produced 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 strategies to constructing Electrical power-transducing motors at nanoscale interfaces.
There was just one trouble though — we did not observe any measurable electrical conduction from the single polymer molecules. We concluded that at the single-molecule level, conducting polymers were really not this sort of excellent conductors, which was relatively disappointing. We Consequently broadened our watch to test to uncover extra promising molecules.
Example (four) of bending configurations in 3D simulations of DNA rods on cees dekker nanopores. A part of the membrane is proven in grey, the rim of your pore is highlighted in pink, plus a 3D rendering in the motion of your DNA rod is shown.
Cees Dekker is Distinguished College Professor at TU Delft. Trained to be a physicist, he pioneered nanotechnology with quite a few discoveries on carbon nanotubes while in the nineteen nineties. Due to the fact 2000, he moved to solitary-molecule biophysics and nanobiology. His present exploration concentrates on (i) nanopores for protein sequencing; (ii) chromosome construction, particularly SMC motor protein; and (iii) creating a living artificial mobile from lifeless molecules. Dekker is really an elected member with the KNAW and fellow on the APS as well as the IOP.

It absolutely was an extremely appealing time, throughout which I gained loads of assistance from Delft College of Technological know-how, exactly where I used to be a professor at enough time, And that i started numerous collaborations with molecular biologists. That aided me study a lot.’
