‘Certainly, which is about ideal. I hunt for a Bodily understanding of biological devices in a bottom-up way. I feel you could distinguish 3 traces of investigate in my group at this time. The initial fears chromosome structure: How would you have a metre-long DNA polymer folded and organised in this type of microscopic cell? We have now developed visualisation methods that let us to check how, for example, SMC proteins loop DNA (video clip on Youtube) as a way to Make up chromosomes.

We have been testing a different program for linking publications to authors. You can help! If you observe any inaccuracies, make sure you
Non-equilibrium folding of specific DNA molecules recaptured as many as a thousand times in a good point out nanopore

Cornelis (Cees) Dekker (Haren, 7 april 1959) is een Nederlandse natuurkundige en universiteitshoogleraar verbonden aan de Technische Universiteit Delft. Van 2010 tot en achieved 2018 was hij tevens directeur van het Kavli Institute of Nanoscience in Delft. Zijn vakgebied is de moleculaire biofysica; hierbij beweegt hij zich op het grensvlak van de natuurkunde en de biologie waarbij hij gebruikmaakt van de zogeheten nanotechnologie, de technieken om aan enkele atomen en moleculen te kunnen meten.
We use nanofabricated microfluidic structures to sample spatial boundaries for microbes and biomimetic vesicles with reconstituted protein networks which evaluate the basic part of spatial confinement on the molecular and cellular level. Our projects include the subsequent:
Case in point (1) of bending configurations in 3D simulations of DNA rods on nanopores. A percentage of the membrane is shown in gray, the rim on the pore is highlighted in red, plus a 3D rendering of the movement of the DNA rod is shown.
The rotors harness Power from the nanoscale drinking water and ion movement that is created by a static chemical or electrochemical likely gradient inside the nanopore, that are founded by way of a salt gradient or applied voltage, respectively. These synthetic nanoengines self-organize and work autonomously in physiological problems, suggesting approaches to developing Strength-transducing motors at nanoscale interfaces.
Really great, but that wasn’t actually in which my curiosity lay. I desired to pioneer and I experienced the feeling that was not achievable, because the most appealing essential insights had already been uncovered. But my discipline experienced developed lots of remarkable new tools to evaluate particular person molecules. I made a decision that I desired to use this to biology, to have a look at it from the Actual physical perspective.’

Later on we spoke all over again briefly simply because Dekker felt that our discussion of his religion promptly turned purely philosophical, whereas Additionally, it concretely will help him in his get the job done.
Enable’s first appear back in the meanwhile any time ceesdekker.net you made a decision to change your aim from superconductivity and nanotubes to biology at the conclusion of the nineteen nineties.
The biophysicist from Delft – who has long been One of the more cited experts from the Netherlands For several years – will take his duty to contribute into the clarification and popularisation of his operate on the border of physics and biology very very seriously and on a regular basis appears within the media; Otherwise to look at his perform, then about the relationship concerning science and his Christian faith.
