Spatial structure facilitates cooperation within a social Problem: empirical evidence from a bacterial Neighborhood
1996, 1st mesoscopic demand density waves gadgets; and initially electrical measurements on just one metallic nanocluster between nanoelectrodes
[Laughs] ‘It absolutely was unquestionably a great danger! At enough time, I was effectively mindful that it could go wrong Which I could come to be significantly less thriving, but I just dismissed that. Curiosity has constantly been my strongest driving pressure. And fortuitously it all labored out.’
Our work was swiftly followed up by Other individuals, most notably by Phaedon Avouris and colleagues at IBM, who in October 1998 revealed their results on transistors comprised of one- and multi-walled carbon nanotubes in Used Physics Letters.
This yielded a breakthrough. In just a few months, we have been able to measure transportation by way of a person one-walled carbon nanotube. Depending on very low-temperature experiments by a brilliant PhD scholar in my team, Sander Tans (now a valued colleague and professor at Delft University of Technology with an Energetic research lab at AMOLF in Amsterdam), we showed that carbon nanotubes were being authentic quantum wires with very extended (micrometres) Digital coherence lengths — confirming theoretical predictions of metallic behaviour.
Experimental stage diagram of negatively supercoiled DNA calculated by magnetic tweezers and fluorescence,
What distinguishes biology from chemistry is the fact these components jointly make up a living program. The trick of reported existence, I believe, lies while in the interactions, the interaction of those molecules. The large query in regards to the origin of lifestyle is still unanswered. How did we ever evolve from easy molecules into the particularly complicated techniques we see today? We don't know. I need to operate on These types of significant, open thoughts.’
Researching DNA loop extrusion by SMC proteins for chromosome architecture with solitary-molecule assays.
What if, in lieu of employing standard major-down silicon electronics, transistors may be constructed from The underside up utilizing one natural molecules given that the switching ceesdekker features? This idea, which turned the basis of now’s area of molecular electronics, to start with emerged inside the nineteen seventies.
Resolving the action dimensions in condensin-pushed DNA loop extrusion identifies ATP binding as being the action-making course of action
An integrated microfluidic platform for quantifying drug permeation throughout biomimetic vesicle membranes
2006, initially demonstration of molecular sorting inside a lab on the chip applying biomotors; discovery of nanobubbles in strong-condition nanopores; and initially estimate of electrokinetic energy conversion within a nanofluidic channel
Let’s initial search back again at this time when you decided to shift your concentrate from superconductivity and nanotubes to biology at the end of the 1990s.
