Making use of solitary-molecule optical and AFM imaging and power-spectroscopy methods, we seek to unravel the mechanistic aspects of the composition and dynamics of chromosomes. Our investigation passions incorporate:
1996, very first mesoscopic cost density waves devices; and 1st electrical measurements on only one steel nanocluster involving nanoelectrodes
‘It absolutely was only a issue of choosing up a reserve on mobile biology and starting to read. I'd come from a globe of extremely-significant vacuums, cryostats and quantum phenomena, and now I used to be Operating at home temperature with molecular biology kits.
Sculpting nano-electrodes which has a transmission electron beam for electrical and geometrical characterization of nanoparticles.
This yielded a breakthrough. Within just a few months, we had been ready to measure transportation via somebody single-walled carbon nanotube. Dependant on minimal-temperature experiments by a superb PhD college student in my team, Sander Tans (now a valued colleague and professor at Delft University of Know-how with the Lively study lab at AMOLF in Amsterdam), we confirmed that carbon nanotubes were being real quantum wires with pretty prolonged (micrometres) Digital coherence lengths — confirming theoretical predictions of metallic behaviour.
Immediate immobilization of native yeast iso-one cytochrome c on bare gold: quick electron relay to redox enzymes and zeptomole protein-movie voltammetry
You are a Christian. If you could make this kind of synthetic mobile, would you be 1 move closer to God, or would the role of God have diminished rather once more?
Flow-driven rotary motors including windmills and drinking water wheels push purposeful procedures in human Modern society. Even though examples of these types of rotary motors also feature prominently in cell biology, their synthetic building with the nanoscale has remained hard. In this article we demonstrate flow-driven rotary motion of a self-organized DNA nanostructure that's docked onto a nanopore in a thin strong-state membrane. An elastic DNA bundle self-assembles into a chiral conformation on phoretic docking on to the reliable-condition nanopore, and subsequently displays a sustained unidirectional rotary motion of up to 20 rev s−1.

There was just one challenge although — we did not observe any measurable electrical conduction from The one polymer molecules. We concluded that at the single-molecule level, conducting polymers have been essentially not these kinds of good conductors, which was somewhat disappointing. We Therefore broadened our view to try to find much more promising molecules.
In 1993 he was appointed as Affiliate Professor at Delft University of Technological know-how. During the mid-1990s Dekker and his staff achieved success with the invention with the Digital Homes of carbon nanotubes, the initial single-molecule transistor as well as other nanoscience.
1999, to start with measurement in the wavefunction of one molecular orbitals of carbon nanotubes; and discovery of kink heterojunctions of carbon nanotubes which gave decisive evidence for the new Luttinger description of interacting electrons in nanotubes
As an example, we look at the nucleopore intricate, a gateway between the mobile nucleus along with the cytoplasm. This is a very complicated procedure and for that reason hard to study in a very cell, so we use biomimetics. We reconstruct holes and then insert particular person factors of the nucleopore advanced to review transportation cees dekker by way of it at the single-molecule stage.’
‘I am driven by ponder and thoughts. On a fabric amount I find solutions in physics, but I practical experience my deepest happiness with God. That faith also drives my science and how I take care of men and women.
