Nanotechnology gives A selection of prospects to add to biology. In this article I'll present examples exactly where nanofabrication – the chance to make confined structures with dimensions at will – is applied to look at the biophysics of one molecules and cells. I'll existing some illustrations from our lab:
Our group studies bacterial mobile division and is also aiming to constitute a ‘base up biology’ in artificial cells that will autonomously divide. Our primary interest lies in mobile division, chromatin construction, and spatial Manage.
Back again in 1991, Sumio Iijima of your NEC Company experienced claimed the synthesis of carbon nanotubes. Band composition calculations prompt that these nanotubes could show metallic band conduction. This is able to be a significant advantage over the conducting polymers we had explored, which were, in fact, disordered semiconductors providing merely variable-variety hopping conductivity.

What distinguishes biology from chemistry is that these parts together make up a dwelling method. The trick of stated everyday living, I believe, lies during the interactions, the interaction of those molecules. The large dilemma with regards to the origin of lifestyle remains to be unanswered. How did we ever evolve from straightforward molecules into your incredibly advanced methods we see currently? We have no idea. I would like to operate on These types of large, open up thoughts.’
