Deep, to overcome optical resolution limit we use localization microscopy method (one among single-molecule technique). Optical microscopy is an appealing biophysical tool used to study small molecules. This is because it is less perturbing to their natural state when compared to other methods.

I agree with preetham. However, the wave nature of light limits the beam of a diameter that can be focussed to half a wavelength commonly known as the diffraction limit. But some biological molecules of interest are somewhere approximately two orders of magnitude smaller and hence we cannot study them by looking down the microscope.

Deep, if this is the condition then each other their diffraction-limited images overlap and their positions cannot be determined accurately .
