Making use of single-molecule optical and AFM imaging and force-spectroscopy procedures, we request to unravel the mechanistic areas of the framework and dynamics of chromosomes. Our analysis interests consist of:

Human Rad51 filaments on double- and one-stranded DNA: correlating normal and irregular forms with recombination function.

Dynamics of initiation, termination and reinitiation of DNA translocation via the motor protein EcoR124I

Our do the job was quickly adopted up by Many others, most notably by Phaedon Avouris and colleagues at IBM, who in Oct 1998 posted their findings on transistors made from single- and multi-walled carbon nanotubes in Applied Physics Letters.

This yielded a breakthrough. In just just a few months, we were in the position to measure transportation by way of an individual one-walled carbon nanotube. Determined by low-temperature experiments by an excellent PhD student in my team, Sander Tans (now a valued colleague and professor at Delft College of Know-how with the 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 conduct.

Microbiology has only been around for just a century, due to the fact we started to examine micro-organisms extra severely. I thought nanobiology was an correct expression, simply because all molecular Organic pertinent interactions happen at the nanoscale: a protein is a number of nanometres in sizing, DNA is two nm thick.’

Lots of associated developments followed, exactly where our group set up distinct transistor variants for example solitary-electron transistors at place temperature and intramolecular nanotube junctions that acted as rectifying diodes, and coupled ceesdekker.net many transistors into modest proof-of-theory electronic circuits.

He also identified time to jot down a number of guides, deliver Just about forty thousand tweets and lead An effective investigate group at Delft College of Engineering. ‘It doesn’t sense like function’, he claims. ‘I’m just terribly curious.’

In 1993, as being a youthful and eager affiliate professor at Delft College of Technological know-how, I'd initially concentrated the study efforts of my team on measuring the electrical conductance of only one conducting-polymer molecule. Within just two decades, we had produced a device by which one wire of the phthalocyaninepolysiloxane polymer was connected between two carefully spaced steel nanoelectrodes.

Right now, we also understood that it ought to be probable to employ only one semiconducting carbon nanotube for making a transistor — and we established out to make it. We stretched personal semiconducting nanotubes across metallic electrodes and used the fundamental silicon substrate for a gate electrode, developing the basic a few-terminal format of a area-effect transistor (Fig.

Instance (4) of bending configurations in 3D simulations of DNA rods on nanopores. A percentage of the membrane is demonstrated in grey, the rim of the pore is highlighted in pink, and also a 3D rendering on the motion of the DNA rod is exhibited.

Later on we spoke all over again briefly simply because Dekker felt that our discussion of his religion promptly turned purely philosophical, whereas Additionally, it concretely will help him in his get the job done.

It had been a very exciting time, all through which I obtained a great deal of aid from Delft University of Technological innovation, where by I was a professor at time, And that i started off several collaborations with molecular biologists. That assisted me understand quite a bit.’
