‘Certainly, that is certainly about right. I seek out a physical knowledge of Organic methods in a very bottom-up way. I believe you could potentially distinguish three strains of research in my group for the time being. The 1st concerns chromosome construction: How will you get a metre-lengthy DNA polymer folded and organised in this type of microscopic mobile? Now we have created visualisation strategies that make it possible for us to check how, for instance, SMC proteins loop DNA (video clip on Youtube) so that you can Develop up chromosomes.

Multicolor imaging on the bacterial nucleoid and cell division proteins with blue, orange, and near-infrared fluorescent proteins
Our operate was promptly adopted up by Many others, most notably by Phaedon Avouris and colleagues at IBM, who in Oct 1998 revealed their results on transistors made out of solitary- and multi-walled carbon nanotubes in Utilized Physics Letters.
This yielded a breakthrough. Within just a few months, we had been capable of evaluate transportation by means of an individual solitary-walled carbon nanotube. According to small-temperature experiments by an excellent PhD university student in my group, Sander Tans (now a valued colleague and professor at Delft College of Technologies by having an active exploration lab at AMOLF in Amsterdam), we showed that carbon nanotubes ended up genuine quantum wires with quite lengthy (micrometres) Digital coherence lengths — confirming theoretical predictions of metallic conduct.
Microbiology has only existed for a century, given that we started to examine micro-organisms additional seriously. I thought nanobiology was an proper phrase, due to the fact all molecular Organic suitable interactions occur at the nanoscale: a protein is a few nanometres in measurement, DNA is 2 nm thick.’
All parameters were being exactly the same for each panel In this particular movie, aside from the Original placement of the 6hb rod (demonstrated in blue) to the nanopore. Simulations that terminated early due to translocation from the rod throughout the pore are marked by a gray qualifications.
Instance (one) of bending configurations in 3D simulations of DNA rods on nanopores. A part of the membrane is revealed in grey, the rim of your pore is highlighted in purple, and a 3D rendering with the motion with the DNA rod is displayed.
‘Sure, I have an understanding of folks were being 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 have to confess that it experienced become a bit bored, I didn’t study A lot anymore. The sphere went much more into the appliance facet, how you can integrate nanotubes into Digital circuits.
Right now, we also recognized that it should be achievable to utilize just one semiconducting carbon nanotube to create a transistor — and we set out to really make it. We stretched particular person semiconducting nanotubes throughout metallic electrodes and utilised the underlying silicon substrate as being a gate electrode, establishing The essential a few-terminal format of a field-effect transistor (Fig.
Due to the fact 2000 he moved to solitary-molecule biophysics and nanobiology, with research from scientific tests of DNA loop extrusion and supercoiling to DNA translocation by means of nanopores. More recently his research has focused on finding out chromatin structure and mobile division with bacteria on chip, when he is additionally seeking to in the long run Develop artificial cells from the bottom up.
Character Physics thanks the nameless reviewers for their contribution to your peer overview of this get the job done.
Electrical transportation in monolayers of phthalocyanine molecular wires and AFM imaging of just one wire bridging two electrodes
The biophysicist from Delft – who has been one of the most cited experts during the Netherlands For some time – usually https://www.ceesdekker.net takes his obligation to lead for the explanation and popularisation of his work within the border of physics and biology particularly significantly and routinely appears during the media; Otherwise to speak about his work, then about the connection amongst science and his Christian faith.
