"A team from the University of Queensland has demonstrated quantum imaging inside living cells for the first time. They were able to map structures within cells at scales as fine as 10nm, offering a 14% resolution enhancement over coherent light. Conventional optical imaging is limited by diffraction but by generating the photons with a more consistent phase as squeezed light the amount of diffraction can be minimized.

The ability to map living cells at this scale represents a significant breakthrough in imaging. These methods promise to reveal important new levels of cellular complexity and deliver profound benefits to biotech and medical research, and 'confirm the longstanding prediction that quantum correlated light can enhance spatial resolution at the nanoscale and in biology.'"

    Would every cell biologist want one? Probably not. Many cell biologists don't even use eletron or confocal microscopy, instead working with introduced fluorescent proteins, sometimes with simple compound microscopes. It depends on the level of the problem... This is one of the most amazing things about biology, there are so many levels to study, from individual DNA bases, to the structure of tangled DNA, , to individual proteins, to the movement of organelles in the cell, etc. This represents a breakthrough at a specific size scale, which could have implications on other processes (let's say you are studying microtubule formation and you discovery the the mechanism of trisomy), but it won't revolutionize all of biology any more than electron microscopy or confocal microscopy. Also, although I wouldn't rule it out, I can't see any clinical use for this (although IANAMD: I am not a medical doctor). Again, look to where electron microscopy is currently used, and those are the applications that will benefit.
