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 Proportions at will – is applied to look at the biophysics of one molecules and cells. I'll existing some illustrations from our lab:
Our group research bacterial mobile division and is particularly aiming to represent a ‘bottom up biology’ in synthetic cells that can autonomously divide. Our most important fascination lies in cell division, chromatin structure, and spatial Command.
[Laughs] ‘It absolutely was unquestionably a great risk! At the time, I was well informed that it could go wrong and that I could develop into much less prosperous, but I just dismissed that. Curiosity has often been my strongest driving power. And luckily everything worked out.’
Our perform was swiftly followed up by Other folks, most notably by Phaedon Avouris and colleagues at IBM, who in Oct 1998 released their results on transistors constructed from solitary- and multi-walled carbon nanotubes in Utilized Physics Letters.
That is a aspiration of mine and we established to work by using a delectable dose of naivety. This can be a thing that will probably produce amazing leads to the extended term, but that does not subject. You shouldn't only want to work within the issues of tomorrow, but also about the thoughts from the day soon after tomorrow.’
SMC complexes can move physical roadblocks bigger than their ring size, indicating a nontopological system for DNA loop extrusion
Size Charge of particular person carbon nanotubes by nanostructuring Along with the scanning tunneling microscope
He also found time to put in writing several textbooks, send Practically forty thousand tweets and guide a successful exploration group at Delft University of Technological know-how. ‘It doesn’t truly feel like do the job’, he states. ‘I’m just terribly curious.’
This "Cited by" rely features citations to the following content articles in Scholar. Those marked * can be distinctive in the write-up from the profile.
But carbon nanotubes have remained a analysis subject of significant curiosity to several. Without a doubt, the outlook on making use of carbon nanotubes to construct realistic products, in regions for example radio-frequency electronics, digital electronics and flexible electronics, continues to be dazzling.

Quite a few new phenomena have been learned, and he and his study group recognized a number one situation Within this industry of investigate. Dekker and his study group learned new physics of nanotubes along with explored the feasibility of molecular electronics. In 1998, they were being https://www.ceesdekker.net the primary to build a transistor based upon just one nanotube molecule.
For example, we think about the nucleopore intricate, a gateway among the cell nucleus as well as cytoplasm. This is a really intricate technique and so hard to analyze in a very cell, so we use biomimetics. We reconstruct holes and then insert particular person aspects from the nucleopore complex to review transport by it at The only-molecule amount.’
It had been an exceptionally interesting time, for the duration of which I gained a lot of assistance from Delft University of Know-how, where by I had been a professor at the time, and I began numerous collaborations with molecular biologists. That assisted me understand quite a bit.’
