Using one-molecule optical and AFM imaging and power-spectroscopy techniques, we request to unravel the mechanistic areas of the construction and dynamics of chromosomes. Our study pursuits incorporate:
Our team scientific tests bacterial cell division and it is aiming to constitute a ‘base up biology’ in artificial cells that will autonomously divide. Our primary desire lies in mobile division, chromatin construction, and spatial control.
Throughout the exact time, the group of Paul McEuen, who was then primarily based for the College of California, Berkeley, showed equivalent effects on ropes of bundled nanotubes. Based on the wrapping angle, nanotubes can can be found in metallic or semiconducting variants, a prediction that we and Charles Lieber’s team at Harvard College independently verified utilizing scanning tunnelling spectroscopy experiments.
Due to the fact 2000, Dekker has shifted the leading concentration of his get the job done to biophysics where by he experiments the Attributes of one biomolecules and cells using the resources of nanotechnology. This modification of area was pushed by his fascination for the exceptional operating of Organic molecular buildings, in addition to because of the prolonged-expression point of view that numerous exciting discoveries can be anticipated With this field.[5] Current traces of research in his biophysics group are inside the regions of:[6]
Dekker is naast zijn wetenschappelijk werk ook bekend vanwege zijn belangstelling voor de relatie tussen geloof en wetenschap en de discussie rond intelligent style in 2005. (nl)
Inside the many years following these discoveries, my research pursuits shifted to biophysics and nanobiology, And that i grew to become significantly less involved in the event of nanotube electronics. The main focus of many researchers in the sphere also shifted to graphene (the place, funnily adequate, the very first graphene ribbons were called ‘nanotubes which might be Reduce open up alongside their length’) just after the invention of the two-dimensional product in 2004.
All parameters were exactly the same for each panel In this particular movie, aside from the Original placement of your 6hb rod (shown in blue) around the nanopore. Simulations that terminated early on cees dekker account of translocation on the rod from the pore are marked by a gray history.
Circulation-driven rotary motors like windmills and drinking water wheels generate useful processes in human Modern society. Even though examples of these kinds of rotary motors also aspect prominently in cell biology, their synthetic building on the nanoscale has remained demanding. Below we reveal flow-driven rotary motion of a self-arranged DNA nanostructure that is definitely docked on to a nanopore in a skinny stable-point out membrane. An elastic DNA bundle self-assembles right into a chiral conformation on phoretic docking on to the stable-point out nanopore, and subsequently shows a sustained unidirectional rotary movement of up to 20 rev s−1.

one). The present–voltage curves confirmed considerable modulations with gate voltage, even at home temperature, which was in step with band bending in a ~0.6 eV bandgap semiconducting nanotube. These details also showed which the conductance might be modulated by 6 orders of magnitude by changing the gate voltage. The outcome of the function — a place-temperature transistor produced from one carbon nanotube molecule — were revealed in Mother nature in Might 1998.
