Utilizing single-molecule optical and AFM imaging and pressure-spectroscopy strategies, we look for to unravel the mechanistic aspects of the composition and dynamics of chromosomes. Our investigation interests contain:
This concern is for testing whether you're a human customer and to prevent automated spam submissions.
Across the same time, the team of Paul McEuen, who was then primarily based at the College of California, Berkeley, showed very similar effects on ropes of bundled nanotubes. With regards to the wrapping angle, nanotubes can are available in metallic or semiconducting variants, a prediction that we and Charles Lieber’s team at Harvard University independently verified making use of scanning tunnelling spectroscopy experiments.
Deposition and atomic pressure microscopy of particular person phthalocyanine polymers involving nanofabricated electrodes
De sterke polarisatie in de discussie rond schepping/evolutie en meer algemeen rond geloof/wetenschap lijkt helaas geen eind te kennen. Toch is er wel degelijk een heilzame middenweg, maar deze krijgt about het algemeen weinig aandacht. Dit boek kan hier wellicht verandering in brengen. Wie de geschiedenis van de relatie tussen geloof en wetenschap in duikt, komt tot verrassende inzichten. De moderne mens leeft fulfilled veel stereotypen die historisch niet verantwoord blijken te zijn. Afgezaagde typeringen als ‘Vroeger dachten we dat de
Within the years following these discoveries, my investigate pursuits shifted to biophysics and nanobiology, and I became less linked to the event of nanotube electronics. The main focus of many scientists in the sector also shifted to graphene (exactly where, funnily sufficient, the first graphene ribbons were being referred to as ‘nanotubes which can be Lower open together their size’) following the invention of the two-dimensional material in 2004.
MATLAB codes for data processing are offered at . Julia codes utilized for numerical simulation are available at .
Atomic power microscopy reveals that vaccinia topoisomerase IB generates filaments on DNA in a very cooperative fashion
In 1993, as being a younger and keen affiliate professor at Delft University of Engineering, I'd initially targeted the investigation endeavours of my group on measuring the electrical conductance of a single conducting-polymer molecule. Inside of two yrs, we experienced produced a device where only one wire of a phthalocyaninepolysiloxane polymer was connected among two carefully spaced metallic nanoelectrodes.
But carbon nanotubes have remained a exploration subject matter of sizeable desire to lots of. Indeed, the outlook on working with carbon nanotubes to construct realistic units, in spots which include radio-frequency electronics, electronic electronics and versatile electronics, continues to be shiny.

Cees Dekker is Distinguished University Professor cees dekker at TU Delft. Educated as being a physicist, he pioneered nanotechnology with numerous discoveries on carbon nanotubes within the 1990s. Because 2000, he moved to single-molecule biophysics and nanobiology. His current research concentrates on (i) nanopores for protein sequencing; (ii) chromosome composition, especially SMC motor protein; and (iii) creating a residing synthetic cell from lifeless molecules. Dekker is definitely an elected member from the KNAW and fellow to the APS and the IOP.
