Super-Resolution

Although conventional microscopy is limited by the difraction limit of roughly the wavelength of the imaged light (or half that), the centroid of a blinking dot can be estimated with a resolution that goes with roughly sqrt of the number of photons. In collaboration with the Shih and Yin labs we explored a new way to get the blinking effect using short oligo hybridization.

Next? Application to Fluorescent in situ Sequencing (FISSEQ).
