Spatial construction facilitates cooperation within a social Problem: empirical evidence from a bacterial Neighborhood

Reconstitution of ultrawide DNA origami pores in liposomes for transmembrane transport of macromolecules

Around the similar time, the group of Paul McEuen, who was then based for the University of California, Berkeley, confirmed related outcomes on ropes of bundled nanotubes. Depending on the wrapping angle, nanotubes can come 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.

Nanofabrication of electrodes with sub-five nm spacing for transport experiments on solitary molecules and metallic clusters

Electrical transportation in monolayers of phthalocyanine molecular wires and AFM imaging of an individual wire bridging two electrodes

MATLAB codes for info processing are available at . Julia codes employed for numerical simulation can be found at .

2000, discovery that nanotubes can carry remarkable substantial present densities; solved the controversial difficulty of electronic transport by DNA molecules by measurements of insulating behavior at the single molecule stage; and demonstration of the AFM technique for solitary-molecule manipulation of nanotubes

In 1993, as being a younger and keen affiliate professor at Delft University of Engineering, I'd in the beginning focused the analysis initiatives of my team on measuring the electrical conductance of a single conducting-polymer molecule. Inside two several years, we experienced produced a device through which only one wire of the phthalocyaninepolysiloxane polymer was connected in between two carefully spaced steel nanoelectrodes.

There was 1 difficulty however — we didn't observe any measurable electrical conduction from The only polymer molecules. We concluded that at the single-molecule degree, conducting polymers have been in fact not these terrific conductors, which was alternatively disappointing. We So broadened our view to test to find more promising molecules.

An built-in microfluidic System for quantifying drug permeation across biomimetic vesicle membranes

Many new phenomena ended up identified, and ceesdekker he and his research team established a number one place With this discipline of research. Dekker and his investigation group uncovered new physics of nanotubes in addition to explored the feasibility of molecular electronics. In 1998, they ended up the initial to make a transistor depending on only one nanotube molecule.

For example, we think about the nucleopore intricate, a gateway among the cell nucleus as well as cytoplasm. This is an extremely complex system and as a consequence challenging to research in a mobile, so we use biomimetics. We reconstruct holes and after that insert unique things in the nucleopore complex to review transport by it at the single-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 achieved 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)
