In this paper, we review nano-Raman techniques based on aperture scanning near-field
optical microscopy (SNOM). Fundamentals of SNOM and aperture-tip-based near-field …

Polymeric materials possess many attractive properties such as high toughness and
recyclability. Some possess excellent biocompatibility, are biodegradable, and can provide …

Conducting composites are typically made by embedding conductive particles in an
otherwise insulating matrix. The resulting materials often exhibit percolation-like electrical …

Evanescent waves play a growing role in many different areas, such as guided optics,
optical-fiber couplers, integrated optical elements, internal reflection spectroscopy, atom …

Much of our understanding of the atomic-scale magnetic structure and the dynamical
properties of solids and liquids was gained from neutron-scattering studies. Elastic and …

Abstract Scanning Near-field Optical Microscopy (SNOM) allows the investigation of optical
properties on subwavelength scales. During the past few years, more and more attention …

Array-based sensors provide an architecture for multianalyte sensing. In this paper, we
report a new approach for array fabrication. Sensors are made by immobilizing different …

Scanning near-field optical microscope tips are produced by mechanically drawing and by
chemical etching of standard single mode fibers. The geometrical shapes and taper angles …

This letter presents a miniature fiber-optic pressure sensor fabricated directly on the tip of a
fiber. The sensor measures only 125 μm in diameter. A Fabry-Pe/spl acute/rot cavity and a …

An improved method for producing fiber tips for scanning near-field optical microscopy is
presented. The improvement consists of chemically etching quartz optical fibers through …
