Spatial framework facilitates cooperation in a very social Predicament: empirical proof from the bacterial Local community
Our team scientific studies bacterial cell division and it is aiming to represent a ‘base up biology’ in synthetic cells that can autonomously divide. Our most important fascination lies in cell division, chromatin structure, and spatial Regulate.
Throughout the exact same time, the team of Paul McEuen, who was then based mostly in the College of California, Berkeley, showed similar effects on ropes of bundled nanotubes. With regards to the wrapping angle, nanotubes can are available in metallic or semiconducting variants, a prediction that we and Charles Lieber’s team at Harvard University independently verified making use of scanning tunnelling spectroscopy experiments.
Sculpting nano-electrodes which has a transmission electron beam for electrical and geometrical characterization of nanoparticles.

Inside the years following these discoveries, my exploration interests shifted to biophysics and nanobiology, And that i became considerably less involved in the event of nanotube electronics. The focus of numerous scientists in the field also shifted to graphene (where by, funnily ample, the first graphene ribbons ended up described as ‘nanotubes which might be cut open together their length’) immediately after the discovery of the two-dimensional product in 2004.
Numerous related developments adopted, the place our group set up different transistor variants which include solitary-electron transistors at space temperature and intramolecular nanotube junctions that acted as rectifying diodes, and coupled numerous transistors into smaller proof-of-theory Digital circuits.
Nanopores depict a chic and adaptable Resource to evaluate solitary molecules. We investigation novel detection modes with reliable-condition nanopores and also a variety of strategies to evaluate proteins with nanopores. Assignments encompass the next:
It looks like you were misusing this function by heading way too rapidly. You’ve been briefly blocked from working with it.
Right now, we also recognized that it should be attainable to work with an individual semiconducting carbon nanotube to generate a transistor — and we set out to make it. We stretched person semiconducting nanotubes throughout metallic electrodes and made use of the fundamental silicon substrate for a gate electrode, developing The fundamental three-terminal ceesdekker structure of the subject-result transistor (Fig.
FtsZ treadmilling is important for Z-ring condensation and septal constriction initiation in bacterial cell division
1999, first measurement on the wavefunction of single molecular orbitals of carbon nanotubes; and discovery of kink heterojunctions of carbon nanotubes which gave decisive proof for your new Luttinger description of interacting electrons in nanotubes
One example is, we consider the nucleopore complex, a gateway involving the cell nucleus plus the cytoplasm. This is an extremely sophisticated process and thus tricky to examine in a cell, so we use biomimetics. We reconstruct holes and then insert particular person components with the nucleopore complicated to study transport as a result of it at The only-molecule amount.’
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 intelligent layout in 2005. (nl)
