The near-field optical interaction between a sharp probe and a sample of interest can be exploited to image, spectroscopically probe, or modify surfaces at a resolution (down to ∼12 nm) inaccessible by traditional far-field techniques. Many of the attractive features of conventional optics are retained, including noninvasiveness, reliability, and low cost. In addition, most optical contrast mechanisms can be extended to the near-field regime, resulting in a technique of considerable versatility… 
Tip-enhanced near-field optical microscopy.
TLDR
The principles of near-field optics are outlined, the mechanisms contributing to local field enhancement and how it can be used to enhance optical signals are discussed and several recent examples of Raman and fluorescence microscopy with 10 nm spatial resolution of single molecules are reviewed.

Breaking the Diffraction Barrier: Optical Microscopy on a Nanometric Scale
TLDR
A near-field probe has been developed that yields a resolution of ∼12 nm (∼λ/43) and signals ∼104- to 106-fold larger than those reported previously and image contrast is demonstrated to be highly polarization dependent.

Super-resolution Aperture Scanning Microscope
TLDR
An ingenious scheme is developed in which evanescent waves are used to illuminate the object, and a magnified image is obtained using a holographic technique, and the resolution capability is determined by the wavelength of the evanescence wave.
