HTTP:: Electron Microscopes Could Soon See Living Cells
--------
Over the years, electron microscopes have generated a wealth of knowledge on many small things, but experts have always resented the fact that the instruments cannot be used to image living samples. The beams of electrons this type of microscope uses to get the job done is very energetic, and can, at best, easily disrupt the natural processes inside, say, a cell. Now, engineers at the Massachusetts Institute of Technology (MIT) have managed to devise improvements to the machine, which may help it be able to do just that in the very near future, the Institute announces. Electron microscopes are also capable of distinguishing individual atoms, which makes them some of the most advanced observation tools in the world. The scanning variety can provide researchers with images that have depth of field, for instance, which would allow for a much better understanding of small structures. Now, MIT Assistant Professor Mehmet Fatih Yanik, together with his student William Putnam, ha!
s devised a type of electron microscope that relies on an established quantum mechanical measurement technique for its observation. This method allows the microscope to sense its target remotely, which means that no damage can come to a sample. In effect, the scientists say, the electrons never touch the object that is being analyzed...
