TLDR
The first SNOM images taken with nanoscopic diamond crystals as a light source are presented, found to be remarkably stable against bleaching and blinking effects.Abstract:
Recently it was shown that a single molecule at cryogenic temperatures could be used as a local light source for illumination of a sample in the near field. Conventional light-emitting systems such as dye molecules and semiconductor quantum dots could also be used for this purpose, but they suffer from lack of photostability. However, colour centres in diamond have been found to be remarkably stable against bleaching and blinking effects. Here we present the first SNOM images taken with nanoscopic diamond crystals as a light source.read more

TL;DR: This work shows how magneto-optical spin detection can be used to determine the location of a spin associated with a single nitrogen-vacancy centre in diamond with nanometre resolution under ambient conditions, and demonstrates the use of a single diamond spin as a scanning probe magnetometer to map nanoscale magnetic field variations.

Optical stethoscopy: Image recording with resolution λ/20
TL;DR: In this paper, an extremely narrow aperture along a test object equipped with fine-line structures was used to demonstrate a resolving power of at least λ/20 which is to be compared with the values of λ 2.3 obtainable in conventional optical microscopy.

Scanning confocal optical microscopy and magnetic resonance on single defect centers
TL;DR: In this article, the fluorescence of individual nitrogen-vacancy defect centers in diamond was observed with room-temperature scanning confocal optical microscopy, and the centers were photostable, showing no detectable change in their fluorescence emission spectrum as a function of time.

On/off blinking and switching behaviour of single molecules of green fluorescent protein
TL;DR: A study of the photophysical behaviour of single molecules of the green fluorescent protein (GFP) derived from the jellyfish Aequorea victoria suggests the possibility of using these GFPs as fluorescent markers for time-dependent cell processes, and as molecular photonic switches or optical storage elements, addressable on the single-molecule level.

Single pentacene molecules detected by fluorescence excitation in a p-terphenyl crystal.

TL;DR: Experiments clearly prove that narrow peaks in the fluorescence excitation spectrum of a pentacene-doped p-terphenyl crystal stem from single molecules, and show the feasibility of the optical study of a single molecule and its local environment.
