cees dekker - An Overview

‘Yes, that is certainly about right. I seek out a Actual physical knowledge of Organic methods in a very base-up way. I think you might distinguish a few strains of study in my group at the moment. The initial problems chromosome composition: How can you have a metre-long DNA polymer folded and organised in such a microscopic cell? We now have developed visualisation strategies that let us to check how, for instance, SMC proteins loop DNA (video clip on Youtube) in an effort to Make up chromosomes.

Regrettably, for years immediately after Iijima’s report, the production of cleanse nanotubes was cumbersome. In 1996, nevertheless, the team of Richard Smalley at Rice College managed to provide one-walled carbon nanotubes at higher produce. Soon following, I contacted Smalley, and we chose to join forces to measure the transportation via a single carbon nanotube.

Dekker is naast zijn wetenschappelijk werk ook bekend vanwege zijn belangstelling voor de relatie tussen geloof en wetenschap en de discussie rond intelligent structure in 2005. (nl)

From the yrs adhering to these discoveries, my analysis interests shifted to biophysics and nanobiology, And that i turned a lot less associated with the development of nanotube electronics. The main target of numerous researchers in the field also shifted to graphene (where, funnily more than enough, the 1st graphene ribbons have been described as ‘nanotubes which have been Slice open along their length’) following the invention of the two-dimensional material in 2004.

Since 2000 he moved to one-molecule biophysics and nanobiology, with investigation from DNA supercoiling scientific studies of nucleosomes and DNA restore proteins to DNA translocation through nanopores. A short while ago his exploration has focused on researching mobile division with germs on chip, while his best curiosity is in the course of acknowledging artificial cells.

2000, discovery that nanotubes can have remarkable substantial present densities; solved the controversial difficulty of electronic transport by DNA molecules by measurements of insulating behavior at The only molecule stage; and demonstration of an AFM method for solitary-molecule manipulation of nanotubes

one). The current–voltage curves confirmed substantial 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 the conductance might be modulated by six orders of magnitude by changing the gate voltage. The outcome of the perform — a home-temperature transistor made out of only one carbon nanotube molecule — have been posted in Nature in May possibly 1998.

Numerous new phenomena were being uncovered, and he and his study team proven a number one placement Within this industry of analysis. Dekker and his research team discovered new physics of nanotubes together with explored the feasibility of molecular electronics. In 1998, they had been the 1st to construct a transistor dependant on just one nanotube molecule.

Stable-point out nanopores have demonstrated being a shockingly multipurpose probe for one-molecule Assessment of DNA. I'll explain several of our new results – exclusively DNA knots – and also our initiatives to grow the capabilities of strong-state nanopores even further, during the way of single-protein detection, graphene nanopores, plasmonic nanopores, and DNA origami nanopores.
