A method of sequencing a plurality of polynucleotides includes: attaching a single DNA template molecule to each of a plurality of attachment elements on a sample container, wherein the average distance between adjacent elements is less than Abbe's limit; applying a stochastic photo-switching chemistry to all of the molecules at the same time to cause the attached molecules to fluoresce in on and off events in up to four different colors by stochastic photo-switching; and imaging the on and off events in a color channel for each color in real-time as the on and off events are occurring for the attached molecules.
