Near-field scanning optical microscopy.

TL;DR: Near-field fluorescence imaging of single proteins in their native cell membrane with incident laser radiation enhanced with an optical antenna in the form of a spherical gold particle attached to a pointed dielectric tip enables a simultaneous recording of the membrane topology.

TL;DR: Isolated europium-doped metal-oxide nanoparticles were probed by size-correlated high-numerical-aperture (far-field) imaging techniques, which revealed several interesting features of doped-nanoparticle luminescence such as Poissonian occupation statistics, size-dependent luminescent efficiency enhancement for particle sizes of <10 nm, and correlation of interesting transient behavior at particle size of <5 nm.

TL;DR: In this paper , a review of up-to-date Raman-based methodologies for red blood cells (RBCs) analysis used in biology and medicine, and compare them with both classical, as well as other spectroscopic and microscopic approaches.

TL;DR: An overview of the evidence supporting the presence of rafts in oligodendrocytes, the myelin‐producing cells of the central nervous system, is provided and their functional significance is discussed.

TL;DR: 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 inaccessible by traditional far-field techniques, resulting in a technique of considerable versatility.

TL;DR: 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.

TL;DR: In this article, the authors proposed a method for optical trapping and alignment of dielectric particles in aqueous environments at the nanometer scale based on the highly enhanced electric field close to a laser-illuminated metal tip and the strong mechanical forces and torque associated with these fields.

TL;DR: In this article, a method for extending microscopic resolution into the ultra-microscopic region was proposed, based on a method proposed by the London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science.
