Protein nanotech in next gen storage

he magnetic spots in disk storage are already smaller than semiconductor feature sizes, and patterned media and heat-assisted recording will allow 10 TB 2.5″ disks in a few years. But then what? Optical protein-based recording could be the answer.

Scientists at a Osaka University lab have demonstrated a photochemical technique for assembling a specific protein on a patterned surface for a rapid method of of recording, reading and erasing of information.

The patterned surface can be manufactured using quantum dot 605-streptavidin conjugates. Under a medium wave UVB laser, the conjugate fluoresces, distinguishing a 1 from a zero.
