‘Yes, that is certainly about right. I seek out a Actual physical understanding of biological units inside a base-up way. I think you may distinguish a few strains of analysis in my team for the time being. The 1st concerns chromosome construction: How would you receive a metre-lengthy DNA polymer folded and organised in this type of microscopic mobile? Now we have created visualisation tactics that make it possible for us to study how, by way of example, SMC proteins loop DNA (online video on Youtube) in order to Develop up chromosomes.
But how do morality, the dignity from the individual, my practical experience with the that means of lifestyle, abide by with the movement of atoms? A purely naturalistic standpoint fails below; a Christian viewpoint, I think, is a way more affordable way to interpret these areas of actuality.’
Back again in 1991, Sumio Iijima on the NEC Company experienced reported the synthesis of carbon nanotubes. Band framework calculations instructed that these nanotubes could show metallic band conduction. This may be a big edge about the conducting polymers we experienced explored, which ended up, in truth, disordered semiconductors featuring basically variable-array hopping conductivity.
Since 2000, Dekker has shifted the principle aim of his perform toward biophysics where he scientific studies the Houses of one biomolecules and cells using the resources of nanotechnology. This modification of industry was driven by his fascination for your impressive performing of Organic molecular structures, in addition to because of the long-term viewpoint that lots of appealing discoveries is usually expected Within this area.[5] Recent traces of exploration in his biophysics team are from the parts of:[six]
This yielded a breakthrough. Inside only some months, we had been able to measure transport by an individual solitary-walled carbon nanotube. According to very low-temperature experiments by a brilliant 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 legitimate quantum wires with quite long (micrometres) electronic coherence lengths — confirming theoretical predictions of metallic conduct.
Our investigate ranges from the biophysics of DNA to artificial cells and further than. Be sure to take a look down below with the spectrum of our recent initiatives.
Numerous connected developments followed, the place our team proven 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 compact evidence-of-basic principle Digital circuits.
He also identified time to jot down numerous guides, deliver Pretty much forty thousand tweets and lead A prosperous analysis team at Delft College of Technological innovation. ‘It ceesdekker doesn’t feel like perform’, he suggests. ‘I’m just terribly curious.’
This "Cited by" count consists of citations to the next articles or blog posts in Scholar. Those marked * may very well be different from your report from the profile.
Dekker started his exploration on solitary carbon nanotubes in 1993 when he set up a completely new line of investigation to study electrical transportation by means of single organic and natural molecules in between nanoelectrodes. In 1996 a breakthrough was understood with carbon nanotubes. This was reached inside a collaboration While using the group of Nobel laureate Richard Smalley. STM and nanolithography techniques ended up used to reveal that these nanotubes are quantum wires at The only-molecule amount, with fantastic physical Homes.

The biophysicist from Delft – who has been one of the most cited experts from the Netherlands For several years – normally takes his duty to add to your clarification and popularisation of his perform in the border of physics and biology extremely very seriously and on a regular basis appears in the media; Otherwise to mention his function, then about the connection concerning science and his Christian religion.
