Midway by means of his vocation, Cees Dekker reinvented himself. Right after decades of hardcore physics, he shifted his emphasis to ‘nanobiology’ at the switch of the millennium. A phrase he coined himself, to be a issue of point.

You regularly become involved in discussions about science and religion. You've got also penned many books on the topic. Don’t you believe that in some unspecified time in the future We are going to know everything Which God’s role might be more than?

Back again in 1991, Sumio Iijima with the NEC Company experienced claimed the synthesis of carbon nanotubes. Band structure calculations recommended that these nanotubes could exhibit metallic band conduction. This could be a substantial benefit above the conducting polymers we had explored, which had been, in reality, disordered semiconductors giving just variable-selection hopping conductivity.

Our work was rapidly followed up by Other people, most notably by Phaedon Avouris and colleagues at IBM, who in October 1998 printed their findings on transistors created from solitary- and multi-walled carbon nanotubes in Applied Physics Letters.

This yielded a breakthrough. Inside only some months, we had been able to measure transportation by means of somebody solitary-walled carbon nanotube. Dependant on lower-temperature experiments by a superb PhD college student in my team, Sander Tans (now a valued colleague and professor at Delft University of Know-how with the Energetic research lab at AMOLF in Amsterdam), we showed that carbon nanotubes were real quantum wires with pretty extended (micrometres) Digital coherence lengths — confirming theoretical predictions of metallic conduct.

Microbiology has only been around for the century, due to the fact we began to study micro-organisms a lot more severely. I assumed nanobiology was an correct term, since all molecular biological appropriate interactions happen for the nanoscale: a protein is a handful of nanometres in size, DNA is 2 nm thick.’

A lot of linked developments adopted, wherever 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 multiple transistors https://www.ceesdekker.net into little proof-of-basic principle Digital circuits.

Dynamic ParB–DNA interactions initiate and maintain a partition condensate for bacterial chromosome segregation

This "Cited by" rely incorporates citations to the subsequent posts in Scholar. The ones marked * could possibly be unique from the post inside the profile.

At this time, we also understood that it ought to be probable to employ only one semiconducting carbon nanotube to help make a transistor — and we established out to make it. We stretched personal semiconducting nanotubes across metallic electrodes and made use of the underlying silicon substrate being a gate electrode, establishing the basic three-terminal format of a subject-outcome transistor (Fig.

‘That considerations the artificial mobile, as Section of the Dutch BaSyC initiative. Craig Venter appeared leading-down in All those days and recognized about 5 hundred genes which are minimally expected for a working mobile. We wish to appear bottom-up: how can we shift from a several molecules to an entire biological technique?

Allow’s 1st glance again at the moment whenever you decided to shift your target from superconductivity and nanotubes to biology at the end of the nineties.
