The Fundamentals of Single Molecule Microscopy.

Presented by Dr. Gurthwin BOSMAN on 1 Jul 2015 from 11:10 to 11:30
Type: Oral Presentation
Session: Photonics
Track: Track C - Photonics


In the last decade, single molecule microscopy has become the technique of choice when sub-diffraction imaging is required [1]. Sub-diffraction imaging using optical microscopes requires that single molecule fluorescent markers be imaged stochastically (in techniques like stochastic optical reconstruction microscopy (STORM) or photoactivated localization microscopy (PALM)) or with very low concentrations such that only a small fraction of the emitters are imaged at any given time [2]. When combining the abovementioned techniques with point-spread function tailoring, three dimensional localization accuracies well below 50 nm are readily achieved [3]. In this presentation the fundamental requirements for achieving high localization accuracies with single molecule microscopy will be discussed. References: [1] B. Flier, et. al.
