Nanotechnology features a range of options to lead to biology. Below I'll current illustrations where nanofabrication – the chance to make confined constructions with dimensions at will – is applied to look at the biophysics of one molecules and cells. I will present some examples from our lab:
Our group research bacterial cell division and is particularly aiming to represent a ‘bottom up biology’ in synthetic cells which can autonomously divide. Our key curiosity lies in cell division, chromatin composition, and spatial Regulate.
Multicolor imaging in the bacterial nucleoid and cell division proteins with blue, orange, and in the vicinity of-infrared fluorescent proteins
Our perform was speedily adopted up by Some others, most notably by Phaedon Avouris and colleagues at IBM, who in Oct 1998 released their results on transistors created from one- and multi-walled carbon nanotubes in Utilized Physics Letters.
2012, discovery that nucleoid occlusion underlies the accuracy of bacterial mobile division; and initial at any time research of your dynamics DNA supercoils and the invention of supercoil hopping
Experimental period diagram of negatively supercoiled DNA measured by magnetic tweezers and fluorescence,
Numerous connected developments followed, in which our group set up distinct transistor variants for example solitary-electron transistors at area temperature and intramolecular nanotube junctions that acted as rectifying diodes, and coupled a number of transistors into modest proof-of-theory electronic circuits.
Studying DNA loop extrusion by SMC proteins for chromosome architecture with solitary-molecule assays.
Let's say, instead of working with traditional major-down silicon electronics, transistors may be developed from The underside up making use of one natural molecules given that the switching factors? This concept, which became The idea of today’s discipline of molecular electronics, first emerged inside the nineteen seventies.
It absolutely was all through this era that Dekker carried out study on magnetic spin techniques and on sound in superconductors and semiconductors.
In 1993 he was appointed as Affiliate Professor at Delft College of Engineering. From the mid-1990s Dekker and his group realized success with the discovery in the Digital Attributes of carbon nanotubes, the very first solitary-molecule transistor together with other nanoscience.
Quite a few new phenomena have been discovered, and he and his exploration group founded a leading posture In this particular field of exploration. Dekker and his study team identified new physics of nanotubes and explored the feasibility of molecular electronics. In 1998, they have been the first to create a transistor based on an individual nanotube molecule.
