Midway by means of his vocation, Cees Dekker reinvented himself. Soon after years of hardcore physics, he shifted his concentration to ‘nanobiology’ in the convert from the millennium. A expression he coined himself, as a subject of fact.

Again in 1991, Sumio Iijima of the NEC Corporation had reported the synthesis of carbon nanotubes. Band structure calculations recommended that these nanotubes could exhibit metallic band conduction. This would be a substantial advantage more than the conducting polymers we had explored, which were, in fact, disordered semiconductors offering merely variable-range hopping conductivity.
Due to the fact 2000, Dekker has shifted the primary focus of his operate to biophysics exactly where he scientific tests the Attributes of single biomolecules and cells using the instruments of nanotechnology. This transformation of discipline was pushed by his fascination for that remarkable functioning of biological molecular constructions, and also via the long-phrase viewpoint that lots of appealing discoveries can be expected Within this discipline.[5] Recent traces of investigate in his biophysics team are in the areas of:[6]
This yielded a breakthrough. Inside of only some months, we have been able to evaluate transportation by way of an individual solitary-walled carbon nanotube. Dependant on lower-temperature experiments by a superb PhD college student in my team, Sander Tans (now a valued colleague and professor at Delft University of Technological know-how using an Lively analysis lab at AMOLF in Amsterdam), we confirmed that carbon nanotubes had been authentic quantum wires with extremely very long (micrometres) electronic coherence lengths — confirming theoretical predictions of metallic behaviour.
Cornelis (Cees) Dekker (Haren, 7 april 1959) is een Nederlandse natuurkundige en universiteitshoogleraar verbonden aan de Technische Universiteit Delft. Van 2010 tot en satisfied 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.
Duration control of personal carbon nanotubes by nanostructuring With all the scanning tunneling microscope
2000, discovery that nanotubes can have extraordinary huge present-day densities; resolved the controversial situation of Digital transportation by means of DNA molecules by measurements of insulating behavior at The only molecule stage; and demonstration of the AFM method for solitary-molecule manipulation of nanotubes
Understanding fundamental processes regulating the spatial and dynamic organisation of the DNA in Reside cells.
one). The present–voltage curves confirmed considerable modulations with gate voltage, even at room temperature, which was in keeping with band bending inside a ~0.six eV bandgap semiconducting nanotube. These information also confirmed which the conductance may be modulated by 6 orders of magnitude by modifying the gate voltage. The results of this work — a area-temperature transistor comprised of an individual carbon nanotube molecule — were being printed in Mother nature in May 1998.
In 1993 he was appointed as Affiliate Professor at Delft College of Engineering. During the mid-nineties Dekker and his staff accomplished accomplishment with the invention of the electronic Houses of carbon nanotubes, the first single-molecule transistor together with other nanoscience.
‘That considerations the artificial cell, as Section of the Dutch BaSyC initiative. Craig Venter looked prime-down in those days and discovered about five hundred genes which might be minimally required for any performing cell. We want to seem base-up: how do we transfer from the few molecules to a whole Organic procedure?

Dekker heeft fundamentele ontdekkingen gedaan ceesdekker op het gebied van koolstof nanobuisjes. Mede vanwege deze werkzaamheden is hij al jaren de meest geciteerde fysicus in Nederland. Tegenwoordig onderzoekt hij satisfied enkel-molecuultechnieken de biofysica van moleculen in de biologische cel. Dekker is naast zijn wetenschappelijk werk ook bekend vanwege zijn belangstelling voor de relatie tussen geloof en wetenschap en de discussie rond clever style in 2005. (nl)
