‘Yes, that is certainly about right. I seek for a physical knowledge of Organic systems in a very base-up way. I believe you could possibly distinguish three lines of investigation in my team in the mean time. The 1st issues chromosome construction: How will you receive a metre-lengthy DNA polymer folded and organised in this type of microscopic mobile? Now we have created visualisation approaches that allow us to study how, by way of example, SMC proteins loop DNA (movie on Youtube) so that you can Develop up chromosomes.
Our group research bacterial mobile division which is aiming to constitute a ‘bottom up biology’ in artificial cells that could autonomously divide. Our principal interest lies in mobile division, chromatin framework, and spatial Handle.
, Groningen researchers current the final results in their endeavours to help make labs much more sustainable and provide techniques for other labs.
Unfortunately, For several years right after Iijima’s report, the creation of thoroughly clean nanotubes was cumbersome. In 1996, having said that, the group of Richard Smalley at Rice College managed to produce solitary-walled carbon nanotubes at superior produce. Soon right after, I contacted Smalley, and we made a decision to join forces to measure the transportation through a single carbon nanotube.
This yielded a breakthrough. In only a few months, we were being capable to measure transportation through an individual one-walled carbon nanotube. Depending on small-temperature experiments by an excellent PhD pupil in my team, Sander Tans (now a valued colleague and professor at Delft University of Know-how with the Lively analysis lab at AMOLF in Amsterdam), we confirmed that carbon nanotubes had been authentic quantum wires with very prolonged (micrometres) Digital coherence lengths — confirming theoretical predictions of metallic behaviour.
Microbiology has only existed for just a century, since we started to research micro-organisms a lot more significantly. I believed nanobiology was an acceptable expression, mainly because all molecular Organic applicable interactions happen at the nanoscale: a protein is a few nanometres in dimension, DNA is 2 nm thick.’
A lot of similar developments adopted, where our group established different transistor variants like single-electron transistors at space temperature and intramolecular nanotube junctions that acted as rectifying diodes, and coupled several transistors into tiny proof-of-principle electronic circuits.
He also located time to put in writing numerous guides, deliver Just about forty thousand tweets and lead An effective investigate group at Delft College of Technologies. ‘It doesn’t sense like work’, he says. ‘I’m just terribly curious.’
Knowledge fundamental procedures regulating the spatial and dynamic organisation of the DNA in live cells.
Dekker started out his study on one carbon nanotubes in 1993 when he put in place a fresh line of study to check electrical transport through solitary natural molecules between nanoelectrodes. In 1996 a breakthrough was recognized with carbon nanotubes. This was accomplished inside of a collaboration Along with the group of Nobel laureate Richard Smalley. STM and nanolithography approaches have been utilized to exhibit that these nanotubes are quantum wires at the single-molecule stage, with exceptional Actual physical Homes.

Allow’s initially glimpse again for the time being if you made a decision to change your focus from superconductivity and nanotubes to biology at the end of the 1990s.
