what is the smallest thing you can see under a microscope?
The worlds strongest microscope the scanning tunneling microscope as a resolution of 0.2 nanometer, this allows the viewer to "see"atomic particles.
For more info about the scanning tunneling microscope you can visit http://en.wikipedia.org/wiki/Scanning_tunneling_microscope
The smallest thing you can see, at good focus, under the microscope is about as long as the wavelength of the light you use. once trying to watch smaller objects, it is impossible to get good focus!

You don't have to use light, you can use massive particles (e.g. Electrons). Since they are subject to quantum mechanics, they have a wavelength as well, and as mentioned before by haimt, this wavelength sets the limit for the resolution. The faster the particles, the smaller the wavelength, and the better the resolution. Essentially, every particle accelerator is a giant microscope that allows us to look into the structure of elementary matter. The largest accelerator is
electrons are the smallest particle to be seen by telescope.i believe you can view quarks too but they are so small that its not exactly "seeing" anymore.
