3D printed nanopores, where 1 cm = 1 nm. Done with my own 3D printer. I did this to get a better idea of spatial considerations when applying these nanopores as single molecule tweezers. From left to right: ClyA, aHL, CsgG, MspA, FraC. I have done single molecule experiments with all of these nanopores before, the actual proteins that is, and I have purified 3 out of the 5 of them before. My research has panned out such that I mostly use ClyA and MspA. Of course, many thanks to the structural biologists who make this sort of thing possible! Note to self- add PDB codes.
