Nanotechnology presents An array of possibilities to contribute to biology. Right here I will current examples the place nanofabrication – the opportunity to make confined buildings with Proportions at will – is applied to look at the biophysics of solitary molecules and cells. I'll existing some illustrations from our lab:
Our group studies bacterial mobile division which is aiming to constitute a ‘bottom up biology’ in artificial cells which will autonomously divide. Our major curiosity lies in mobile division, chromatin framework, and spatial Handle.
Back in 1991, Sumio Iijima from the NEC Corporation had reported the synthesis of carbon nanotubes. Band framework calculations instructed that these nanotubes could show metallic band conduction. This may be a big edge about the conducting polymers we experienced explored, which have been, the truth is, disordered semiconductors giving just variable-selection hopping conductivity.
2007, first true-time detection of strand Trade in homologous recombination by RecA; discovery of a minimal persistence duration of finishes of microtubules; and resolved the system of biosensing with carbon nanotubes
To look through Academia.edu and the wider Online faster and even more securely, remember to have a several seconds to upgrade your browser.
Our exploration ranges with the biophysics of DNA to artificial cells and outside of. You should have a look under on the spectrum of our existing tasks.
We use nanofabricated microfluidic structures to sample spatial boundaries for microbes and biomimetic vesicles with reconstituted protein networks which evaluate the basic part of spatial confinement on the molecular and cellular degree. Our projects include the subsequent:
Dynamic ParB–DNA interactions initiate and maintain a partition condensate for bacterial chromosome segregation
‘Indeed, I understand men and women were stunned at some time. At the end of the nineties, Once i was in my forties, I had been Professor of Molecular Electronics and I've to admit that it experienced turn into a bit bored, I didn’t find out much any more. The sphere went more into the appliance aspect, how you could integrate nanotubes into electronic circuits.
Resolving the stage dimension in condensin-driven DNA loop extrusion identifies ATP binding as the step-generating process
FtsZ treadmilling is essential for Z-ring condensation and septal constriction initiation in bacterial cell division
2006, to start with demonstration of molecular sorting cees dekker within a lab over a chip working with biomotors; discovery of nanobubbles in solid-state nanopores; and 1st estimate of electrokinetic Electrical power conversion inside a nanofluidic channel
Visualization of unstained DNA nanostructures with Sophisticated in-target transmission electron microscopy approaches
Good-point out nanopores have tested to generally be a surprisingly versatile probe for single-molecule analysis of DNA. I'll explain several of our new results – exclusively DNA knots – together with our initiatives to grow the capabilities of strong-state nanopores even further, in the direction of one-protein detection, graphene nanopores, plasmonic nanopores, and DNA origami nanopores.
