Nanotechnology features a range of possibilities to contribute to biology. Right here I will present examples in which nanofabrication – the opportunity to make confined constructions with dimensions at will – is utilised to look at the biophysics of solitary molecules and cells. I'll current some illustrations from our lab:
But how do morality, the dignity of the individual, my expertise from the meaning of everyday living, comply with from your motion of atoms? A purely naturalistic point of view fails right here; a Christian standpoint, I believe, is a much more acceptable approach to interpret these aspects of fact.’
Back in 1991, Sumio Iijima in the NEC Corporation had described the synthesis of carbon nanotubes. Band composition calculations prompt that these nanotubes could show metallic band conduction. This may be an important gain about the conducting polymers we experienced explored, which ended up, the truth is, disordered semiconductors giving just variable-selection hopping conductivity.
Our get the job done was promptly adopted up by others, most notably by Phaedon Avouris and colleagues at IBM, who in October 1998 published their findings on transistors produced from single- and multi-walled carbon nanotubes in Applied Physics Letters.
This yielded a breakthrough. In only a few months, we ended up in a position to evaluate transport as a result of a person one-walled carbon nanotube. Depending on low-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 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 study micro-organisms far more severely. I believed nanobiology was an ideal expression, mainly because all molecular Organic suitable interactions occur for the nanoscale: a protein is some nanometres in sizing, DNA is two nm thick.’
We use nanofabricated microfluidic structures to sample spatial boundaries for microbes and biomimetic vesicles with reconstituted protein networks which evaluate the elemental purpose of spatial confinement for the molecular and mobile degree. Our tasks consist of the following:
He also identified time to jot down a number of textbooks, send Just about forty thousand tweets and lead A prosperous research group at Delft College of Technologies. ‘It doesn’t sense like function’, he claims. ‘I’m just terribly curious.’
This "Cited by" depend consists of citations to the next articles or blog posts in Scholar. Those marked * may very well be various from your report from the profile.
At the moment, we also realized that it should be possible to use a single semiconducting carbon nanotube to make a transistor — and we established out to really make it. We stretched ceesdekker particular person semiconducting nanotubes throughout metallic electrodes and employed the underlying silicon substrate as a gate electrode, establishing The essential 3-terminal format of a industry-outcome transistor (Fig.

Nanoscientist Cees Dekker is an amiable and flamboyant person who seems Considerably more youthful compared to the sixty two decades he essentially is – trendy glasses, psychedelic shirt, partaking smile – although not a single to waste time. He usually takes his time, but not more than required.

Dekker heeft fundamentele ontdekkingen gedaan op het gebied van koolstof nanobuisjes. Mede vanwege deze werkzaamheden is hij al jaren de meest geciteerde fysicus in Nederland. Tegenwoordig onderzoekt hij met enkel-molecuultechnieken de biofysica van moleculen in de biologische cel. Dekker is naast zijn wetenschappelijk werk ook bekend vanwege zijn belangstelling voor de relatie tussen geloof en wetenschap en de discussie rond smart style and design in 2005. (nl)
