‘The second is nanopores, which is our oldest line of research and which has now triggered DNA sequencers according to nanopores. We pull person DNA strands through a nanopore and will then browse from the nucleotide sequence. Quite not long ago, we even managed to read through out an individual protein for The very first time utilizing This system. But this line of investigation is not simply about acquiring applications, and also about true biological concerns.
It was only while in the nineteen nineties even though, when nanotechnology experienced Superior to the degree where by single molecules may be manipulated, that the first experimental units commenced to appear.
Back again in 1991, Sumio Iijima with the NEC Company experienced described the synthesis of carbon nanotubes. Band construction calculations advised that these nanotubes could exhibit metallic band conduction. This might be a big gain around the conducting polymers we experienced explored, which were, actually, disordered semiconductors providing merely variable-variety hopping conductivity.
Considering that 2000, Dekker has shifted the primary concentration of his work in direction of biophysics where by he research the Homes of one biomolecules and cells utilizing the tools of nanotechnology. This variation of industry was driven by his fascination for your impressive performing of Organic molecular buildings, together with by the lengthy-phrase point of view that many fascinating discoveries might be predicted With this field.[five] Current lines of analysis in his biophysics group are while in the regions of:[six]
2012, discovery that nucleoid occlusion underlies the precision of bacterial cell division; and initially ever review in the dynamics DNA supercoils and the invention of supercoil hopping
Experimental stage diagram of negatively supercoiled DNA calculated by magnetic tweezers and fluorescence,
MATLAB codes for information processing are offered at . Julia codes employed for numerical simulation can be found at .
Atomic pressure microscopy shows that vaccinia topoisomerase IB generates filaments on DNA in a very cooperative fashion
This "Cited by" cees dekker count involves citations to the next article content in Scholar. Those marked * may be various through the short article during the profile.
1). The existing–voltage curves showed sizeable modulations with gate voltage, even at space temperature, which was according to band bending within a ~0.six eV bandgap semiconducting nanotube. These information also confirmed that the conductance may be modulated by 6 orders of magnitude by modifying the gate voltage. The effects of this get the job done — a room-temperature transistor made out of a single carbon nanotube molecule — have been printed in Character in May perhaps 1998.
[14] In 2005 Dekker became linked to Netherlands-huge discussions about Intelligent Design, a motion that he has because clearly distanced himself from. Dekker advocates that science and religion are not in opposition but is often harmonized.
In the meantime, to ensure ongoing help, we are exhibiting the website without kinds and JavaScript.
Publisher’s Take note Springer Character stays neutral with regard to jurisdictional promises in released maps and institutional affiliations.
2013, controlled shaping of Are living bacterial cells into arbitrary shapes; and discovery of spontaneous fluctuations in the handedness of histone tetrasomes
