If you're just using an Olympus microscope at visible frequencies than these images are diffraction-limited.
Have you thought about trying the experiment using a plasmonic superlens? You can get Lambda/8 resolution while still taking far-field images. Potentially you could more accurately resolve your structures, assuming they remained close to the axis of the superlens grating during filming.

I used a digital CCD camera coupled to an Olympus microscope. The camera is cheap!
Actually the other movie of the single nanorod is better because I was able to focus the microscope/camera using longer wavelength then switching to the longer wavelength to photodimerize the nanorod.
These are 200 nm thick, 60 micron long organic nanorods that move when irradiated with light. If we irradiate a bigger size chunk of this material say a 1 mm size crystal, it will fracture and turn to powder. This is a novel example of light initiated motion on the nanoscale. We could use them as nano-actuators or nano-engines.

How did you capture images in such detail of 200 nm ????

Cool... but what are they for?
