Nanotechnology features a range of options to lead to biology. Below I'll current illustrations where nanofabrication – the ability to make confined structures with dimensions at will – is employed to examine the biophysics of solitary molecules and cells. I will present some examples from our lab:
1996, initial mesoscopic demand density waves gadgets; and initially electrical measurements on one metallic nanocluster in between nanoelectrodes
Dynamics of initiation, termination and reinitiation of DNA translocation with the motor protein EcoR124I
Our operate was speedily followed up by Other individuals, most notably by Phaedon Avouris and colleagues at IBM, who in October 1998 revealed their results on transistors made out of solitary- and multi-walled carbon nanotubes in Used Physics Letters.
This yielded a breakthrough. In only a few months, we ended up capable of evaluate transport by a person one-walled carbon nanotube. Depending on small-temperature experiments by an excellent PhD university student in my group, Sander Tans (now a valued colleague and professor at Delft College of Technologies by having an active investigate lab at AMOLF in Amsterdam), we showed that carbon nanotubes ended up genuine quantum wires with quite long (micrometres) electronic coherence lengths — confirming theoretical predictions of metallic conduct.
Our exploration ranges within the biophysics of DNA to artificial cells and further than. Be sure to take a look underneath for the spectrum of our latest initiatives.
Lots of related developments followed, exactly where our group set up distinct transistor variants for example one-electron transistors at home temperature and intramolecular nanotube junctions that acted as ceesdekker rectifying diodes, and coupled multiple transistors into little proof-of-principle electronic circuits.
Example (one) of bending configurations in 3D simulations of DNA rods on nanopores. A portion of the membrane is demonstrated in gray, the rim on the pore is highlighted in red, as well as a 3D rendering of your movement of the DNA rod is shown.
The rotors harness energy from the nanoscale drinking water and ion flow that is created by a static chemical or electrochemical likely gradient within the nanopore, which are recognized by way of a salt gradient or used voltage, respectively. These artificial nanoengines self-organize and work autonomously in physiological problems, suggesting approaches to developing Strength-transducing motors at nanoscale interfaces.
Bulk-floor coupling identifies the mechanistic relationship concerning Min-protein styles in vivo and in vitro
Tests pseudotopological and nontopological models for SMC-driven DNA loop extrusion versus roadblock-traversal experiments
In the meantime, to ensure ongoing help, we are exhibiting the positioning with out styles and JavaScript.

2013, controlled shaping of Stay bacterial cells into arbitrary shapes; and discovery of spontaneous fluctuations from the handedness of histone tetrasomes
