‘The second is nanopores, that's our oldest line of investigation and that has now resulted in DNA sequencers determined by nanopores. We pull specific DNA strands by way of a nanopore and can then study off the nucleotide sequence. Pretty recently, we even managed to browse out only one protein for The 1st time employing This method. But this line of study is not just about creating tools, but will also about authentic biological concerns.
It absolutely was only while in the nineteen nineties however, when nanotechnology experienced Innovative to a degree exactly where one molecules might be manipulated, that the 1st experimental gadgets started to look.
[Laughs] ‘It had been undoubtedly a terrific chance! At enough time, I used to be very well mindful that it could go Improper and that I could turn out to be much less successful, but I just disregarded that. Curiosity has normally been my strongest driving pressure. And by chance all of it worked out.’
2007, 1st real-time detection of strand exchange in homologous recombination by RecA; discovery of the low persistence size of finishes of microtubules; and resolved the mechanism of biosensing with carbon nanotubes

Since 2000 he moved to single-molecule biophysics and nanobiology, with investigate from DNA supercoiling scientific tests of nucleosomes and DNA repair service proteins to DNA translocation by way of nanopores. A short while ago his investigation has focused on studying mobile division with microorganisms on chip, whilst his ultimate fascination is inside the direction of knowing synthetic cells.
2000, discovery that nanotubes can have incredible big latest densities; resolved the controversial concern of Digital transportation through DNA molecules by measurements of insulating conduct at The one molecule amount; and demonstration of an AFM approach for one-molecule manipulation of nanotubes
This "Cited by" depend includes citations to the following content articles in Scholar. The ones marked * could possibly be unique within the article within the profile.
Presently, we also understood that it ought to 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 employed the underlying silicon substrate as a gate electrode, creating The fundamental 3-terminal layout of the subject-result transistor (Fig.

2001, discovery of single-electron transistors at space temperature depending on nanotubes; realization of 1st logic circuits with carbon nanotube units; and discovery on the molecular framework of DNA mend enzymes with AFM
Developments in nanotechnology within the 1990s produced creating electronic devices from single molecules a possibility. Cees Dekker recounts how his team created a home-temperature transistor dependant on only one carbon nanotube.
