Many potentially insurmountable problems: Data surfaces need to be extraordinarily stable: not bacteria but bacteria proteins. Coding for bianry wuld be bruned accross like protein strands>
1) No two protein strands are exactly alike
2) Temperature of the drive would have to be strickly controlled as any changes cause protein length and configuration changes.
3) Media would have to be stored in total dark as protein is light sensitive.
4) Media would have to be coated in such a way that all potential changes in Ph would be eliminated. So a non-pourus electrostatically neutral metal surface wuold have to be used: Gold or Platinum.
calling those problems insurmountable might be going a bit too far.
1) They are, for the most part all alike enough to do what they have to do (respond to light). Sure amino acids are misplaced once in a while, but the majority of them would most likely be usable
2) The temperature may not have to be SO strictly controlled, it really depends on the protein. Some proteins have the structural integrity to withstand greater temperature changes, and we can easily breed bacteria that produce proteins that are more resistant to temperature changes. TAQ polymerase, for instance is a protein found in bacteria that thrive in hot springs. It easily maintains its shape at room temperature or at extremely high temperatures.
3) It isnt hard to design a case that sheilds media from light when its outdside of the media reader/ writer (film for instance) And this disk could very well be permanantly within the computer, within a case...
4)That is the most legitimate problem that i see, but a) we dont know how vulnerable the protein is to ph change B) we dont know what the proteins ideal ph range is (it might be very unlikely that the ph would be outside of this... so that may or may not be a problem but in what type of situation are you envisioning the ph change??
im sure that the HARVARD scientist developing this knows a few things about proteins light temp and ph... thats all extremely basic
that atomic drive ish looks pretty cool though
