Making use of solitary-molecule optical and AFM imaging and force-spectroscopy procedures, we search for to unravel the mechanistic facets of the construction and dynamics of chromosomes. Our research pursuits contain:
But how do morality, the dignity of your individual, my knowledge in the meaning of life, observe through the movement of atoms? A purely naturalistic standpoint fails listed here; a Christian perspective, I feel, is a much more affordable solution to interpret these areas of actuality.’
Again in 1991, Sumio Iijima in the NEC Corporation experienced noted the synthesis of carbon nanotubes. Band composition calculations instructed that these nanotubes could exhibit metallic band conduction. This is able to be a big benefit around the conducting polymers we experienced explored, which were, in actual fact, disordered semiconductors giving simply variable-vary hopping conductivity.
Our do the job was swiftly followed up by Other individuals, most notably by Phaedon Avouris and colleagues at IBM, who in October 1998 printed their conclusions on transistors made from one- and multi-walled carbon nanotubes in Used Physics Letters.
This yielded a breakthrough. Within just a few months, we had been ready to measure transportation via someone single-walled carbon nanotube. Based upon reduced-temperature experiments by a superb PhD pupil in my team, Sander Tans (now a valued colleague and professor at Delft University of Technological innovation with an Energetic research 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.
Electrical transportation in monolayers of phthalocyanine molecular wires and AFM imaging of a single wire bridging two electrodes
What distinguishes biology from chemistry is usually that these elements alongside one another make up a residing system. The key of stated lifetime, I believe, lies from the interactions, the interplay of All those molecules. The big concern concerning the origin of lifetime is still unanswered. How did we ever evolve from very simple molecules to the exceptionally sophisticated units we see these days? We don't know. I need to work on these kinds of major, open queries.’
2011, 1st in vitro measurements of transport across a cees dekker single biomimetic nuclear pore complicated; improvement of multiplexed magnetic tweezers for kilo-molecule experiments; and resolved the system of homology recognition in DNA homologous recombination
You will help our author matching procedure! When you observe any publications incorrectly attributed to this creator, you should register and mark matches as correct or incorrect.
Quite cool, but that wasn’t actually wherever my interest lay. I wished to pioneer And that i experienced the feeling that was no more probable, because the most appealing essential insights had presently been uncovered. But my subject experienced developed several enjoyable new tools to measure personal molecules. I made a decision which i needed to apply this to biology, to look at it from a physical perspective.’
Testing pseudotopological and nontopological types for SMC-pushed DNA loop extrusion towards roadblock-traversal experiments
Several new phenomena were being uncovered, and he and his study team set up a number one position in this discipline of study. Dekker and his exploration group learned new physics of nanotubes in addition to explored the feasibility of molecular electronics. In 1998, they ended up the very first to make a transistor depending on only one nanotube molecule.
2005, discovery with the mechanism of DNA uncoiling by topoisomerase enzymes; discovery of prolonged-range conformational alterations in Mre11/DNA repair complexes; and 1st drive measurements on a DNA molecule in the nanopore
The biophysicist from Delft – who has become Just about the most cited scientists in the Netherlands For some time – usually takes his accountability to contribute to the rationalization and popularisation of his operate on the border of physics and biology very seriously and on a regular basis appears in the media; Otherwise to mention his function, then about the connection amongst science and his Christian faith.
