Employing single-molecule optical and AFM imaging and power-spectroscopy strategies, we look for to unravel the mechanistic aspects of the composition and dynamics of chromosomes. Our investigation interests include:
Our team experiments bacterial mobile division and is also aiming to constitute a ‘base up biology’ in artificial cells that will autonomously divide. Our primary desire lies in mobile division, chromatin construction, and spatial control.
[Laughs] ‘It was undoubtedly a fantastic threat! At time, I was nicely aware that it could go Improper and that I could turn out to be much less thriving, but I just overlooked that. Curiosity has generally been my strongest driving pressure. And fortuitously it all labored out.’
Our do the job was immediately adopted up by others, most notably by Phaedon Avouris and colleagues at IBM, who in October 1998 printed their findings on transistors constructed from solitary- and multi-walled carbon nanotubes in Utilized Physics Letters.
This yielded a breakthrough. Within just only a few months, we were being capable of evaluate transport through someone one-walled carbon nanotube. Determined by low-temperature experiments by an excellent PhD student in my group, Sander Tans (now a valued colleague and professor at Delft College of Engineering having an active investigate lab at AMOLF in Amsterdam), we showed that carbon nanotubes ended up genuine quantum wires with really extensive (micrometres) electronic coherence lengths — confirming theoretical predictions of metallic conduct.
Microbiology has only been around for any century, considering that we began to review micro-organisms extra very seriously. I assumed nanobiology was an correct term, because all molecular biological related interactions take place at the nanoscale: a protein is a couple of nanometres in dimension, DNA is 2 nm thick.’
All parameters were being the same for each panel On this video clip, apart from the First placement with the 6hb rod (revealed in blue) over the nanopore. Simulations that terminated early due to translocation from the rod throughout the pore are marked by a gray history.
Dynamic ParB–DNA interactions initiate and manage a partition condensate for bacterial chromosome segregation
‘Of course, I comprehend men and women were stunned at some time. At the end of the nineties, Once i was in my forties, I had been Professor of Molecular Electronics and I've to admit that it had turn into a little bit bored, I didn’t find out A great deal any more. The sphere went more into the appliance aspect, how you could integrate nanotubes into electronic circuits.
At the moment, we also recognized that it should be possible to use a single semiconducting carbon nanotube to help make a transistor — and we established out to really make it. We stretched specific semiconducting nanotubes across metallic electrodes and utilized the fundamental silicon substrate to be a gate electrode, developing The fundamental three-terminal structure of the discipline-impact transistor (Fig.

Nanoscientist Cees Dekker is really an amiable and flamboyant male who appears Significantly younger than the sixty two several years he truly is https://www.ceesdekker.net – fashionable Eyeglasses, psychedelic shirt, participating smile – but not a person to squander time. He will take his time, but no more than important.
For instance, we think about the nucleopore advanced, a gateway involving the cell nucleus and also the cytoplasm. This is a really challenging program and therefore tricky to examine inside a mobile, so we use biomimetics. We reconstruct holes then insert person features on the nucleopore complicated to check transport as a result of it at The only-molecule amount.’
‘I'm pushed by marvel and questions. On a material degree I uncover solutions in physics, but I practical experience my deepest contentment with God. That religion also drives my science and how I cope with folks.
