Applying one-molecule optical and AFM imaging and power-spectroscopy methods, we seek to unravel the mechanistic components of the framework and dynamics of chromosomes. Our study interests involve:
You frequently get involved in discussions about science and religion. You may have also created quite a few textbooks on the subject. Don’t you are convinced at some time we will know anything Which God’s part will be in excess of?
[Laughs] ‘It had been undoubtedly a fantastic threat! At time, I was well aware that it could go Incorrect and that I could turn out to be much less profitable, but I just overlooked that. Curiosity has constantly been my strongest driving power. And fortuitously it all labored out.’
Our perform was swiftly followed up by Other folks, most notably by Phaedon Avouris and colleagues at IBM, who in Oct 1998 released their conclusions on transistors constructed from one- and multi-walled carbon nanotubes in Utilized Physics Letters.
This yielded a breakthrough. Within just only a few months, we ended up capable of evaluate transport as a result of a person one-walled carbon nanotube. Depending on small-temperature experiments by an excellent PhD university student in my group, Sander Tans (now a valued colleague and professor at Delft College of Engineering having an active exploration lab at AMOLF in Amsterdam), we confirmed that carbon nanotubes have been legitimate quantum wires with extremely very long (micrometres) electronic coherence lengths — confirming theoretical predictions of metallic behaviour.
Microbiology has only existed for just a century, since we started to research micro-organisms a lot more significantly. I assumed nanobiology was an correct time period, for the reason that ceesdekker.net all molecular Organic applicable interactions occur within the nanoscale: a protein is a handful of nanometres in sizing, DNA is two nm thick.’
Several relevant developments adopted, the place our team recognized unique transistor variants which include one-electron transistors at home temperature and intramolecular nanotube junctions that acted as rectifying diodes, and coupled various transistors into small evidence-of-basic principle Digital circuits.
Illustration (1) of bending configurations in 3D simulations of DNA rods on nanopores. A part of the membrane is shown in gray, the rim of the pore is highlighted in purple, along with a 3D rendering with the motion on the DNA rod is displayed.
What if, in place of making use of standard top rated-down silicon electronics, transistors could possibly be crafted from the bottom up applying solitary natural and organic molecules since the switching features? This idea, which turned the basis of currently’s field of molecular electronics, initially emerged within the seventies.
But carbon nanotubes have remained a research topic of considerable interest to many. In truth, the outlook on applying carbon nanotubes to make realistic products, in regions for example radio-frequency electronics, digital electronics and flexible electronics, continues to be shiny.

Cees Dekker is Distinguished University Professor at TU Delft. Qualified being a physicist, he pioneered nanotechnology with a lot of discoveries on carbon nanotubes while in the nineties. Considering that 2000, he moved to solitary-molecule biophysics and nanobiology. His existing analysis focuses on (i) nanopores for protein sequencing; (ii) chromosome structure, especially SMC motor protein; and (iii) developing a dwelling synthetic cell from lifeless molecules. Dekker is definitely an elected member of the KNAW and fellow to the APS and the IOP.

It had been a very exciting time, for the duration of which I been given lots of assist from Delft College of Technologies, the place I had been a professor at the time, and I started out various collaborations with molecular biologists. That served me discover a whole lot.’
