‘Indeed, that is about appropriate. I search for a Bodily idea of biological devices inside a bottom-up way. I do think you might distinguish a few lines of investigation in my group in the mean time. The very first considerations chromosome structure: How will you have a metre-long DNA polymer folded and organised in this type of microscopic cell? We have produced visualisation methods that allow for us to check how, for instance, SMC proteins loop DNA (movie on Youtube) so that you can Develop up chromosomes.

As being a human being, I provide the biblical assignment to take a look at and use every thing in development for the advantage of my neighbour. I never encounter any conflict amongst religion and science. Quite the opposite, my religion stimulates me to do science, to become open-minded on this planet.’
Due to the fact 2000, Dekker has shifted the main emphasis of his do the job in the direction of biophysics the place he experiments the Qualities of solitary biomolecules and cells utilizing the instruments of nanotechnology. This transformation of discipline was pushed by his fascination for that remarkable working of biological molecular buildings, as well as from the prolonged-expression standpoint that numerous fascinating discoveries could be predicted With this industry.[five] Current lines of exploration in his biophysics team are during the parts of:[6]
This yielded a breakthrough. Within just only a few months, we were being 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 showed that carbon nanotubes were being real quantum wires with incredibly lengthy (micrometres) Digital coherence lengths — confirming theoretical predictions of metallic conduct.
Cornelis (Cees) Dekker (Haren, seven 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 form microorganisms into kinds that deviate from their organic phenotype. Especially, I will clearly show our power to form Dwell E. coli germs into novel shapes like rectangles, squares, triangles and circles.
Atomic drive microscopy displays that vaccinia topoisomerase IB generates filaments on DNA in a very cooperative manner
Knowing basic processes regulating the spatial and dynamic organisation on the DNA in Stay cells.
one). The current–voltage curves showed sizeable modulations with gate voltage, even at space temperature, which was according to band bending within a ~0.six eV bandgap semiconducting nanotube. These details also showed which the conductance might be modulated by six orders of magnitude by https://www.ceesdekker.net switching the gate voltage. The outcome of the function — a place-temperature transistor made from an individual carbon nanotube molecule — were being revealed in Mother nature in Could 1998.
An integrated microfluidic System for quantifying drug permeation throughout biomimetic vesicle membranes
2006, to start with demonstration of molecular sorting inside a lab over a chip applying biomotors; discovery of nanobubbles in strong-condition nanopores; and initially estimate of electrokinetic energy conversion within a nanofluidic channel
Developments in nanotechnology within the 1990s produced creating electronic devices from single molecules a possibility. Cees Dekker recounts how his group produced a space-temperature transistor according to just one carbon nanotube.
Illustration (two) of bending configurations in 3D simulations of DNA rods on nanopores. A part of the membrane is revealed in grey, the rim with the pore is highlighted in crimson, in addition to a 3D rendering in the movement in the DNA rod is exhibited.
