Summary and Comments

They use an OT fitted with high resolution ionic current detection to put DNA molecules (attached to beads) into nanopores to determine the level of interaction between the nanopore walls and the DNA. By coupling OT with nanopores they claim to be able to control the DNA speed and position and hopefully can answer two questions that they lay down in the intro.

They use a 1.5W Crystalaser for their setup which is what we are going to do real soon! They also use half-lambda plate and PBS cube to attenuate the power of the laser. They use a beam expander and two lenses (of differing foci) for back aperture overfilling. They talk about the other setups (chip construction, etc) but I don't care too much so I won't detail here.
