“…Also, nanoscale changes in surface morphology are best tracked when the probe has a sharply pointed tip, and a smooth taper assists in the prevention of light leakage from the probe. Several methods have been used to prepare sharply tapered NSOM probes for optical spectroscopy, including chemical etching (18 -21, 44-46), focused ion beam milling (47), heat-pulling (15,16), micromachining (48,49), and hybrid heat-pulling/chemical etching combinations (50). Only two methods, namely heat-pulling (33,34) and chemical etching (27 -29, 32, 37, 41), have been specified in the literature as methods for fabricating apertured probes for near-field laser ablation, and these methods are described in the following paragraphs.…”

Traditional laser ablation is a well-known method of solid sampling for surface characterization, but the resolution of the technique has been limited by the diameter of the incident laser beam and is typically on the order of 100-200 mm. Unfortunately, this microscale resolution can be too low to characterize isolated surface features that have submicron dimensions. Near-field laser ablation is an emerging analytical tool for nanoscale, high-resolution surface analysis. In this review, applications of near-field laser ablation for solid sample introduction are explored. Also, a descriptive overview of the near-field region is given, and methods of generating a near-field region and several processes for tip manufacture are described.

“…Possible uses of nanosized biomolecules or composites are in magnetic recording (when combined with magnetic nanoclusters; Mayes et al 2003), molecular-scale spintronics (magnetic switches) (Ruben et al 2003), coupling of nanodevices with optical signals [already shown for virions (Dragnea et al 2003;Islam et al 1997)], and molecular-scale electronic switches (Keren et al 2003). For extreme cases, quantum mechanics plays a huge role, e.g.…”

Biomolecules are vitally important elements in nanoscale science and also in future nanotechnology. Their shape and their chemical and physical functionality can give them a big advantage over inorganic and organic substances. While this becomes most obvious in proteins and peptides, with their complicated, but easily controlled chemistry, other biomolecular substances such as DNA, lipids and carbohydrates can also be important. In this review, the emphasis is on one-dimensional molecules and on molecules that self-assemble into linear structures, and on their potential applications. An important aspect is that biomolecules can act as templates, i.e. their shape and chemical properties can be employed to arrange inorganic substances -- such as metals or metal compounds -- on the nanometre scale. In particular, rod- and tube-like nanostructures can show physical properties that are different from those of the bulk material, and thus these structures are likely to be a basis for new technology.

“…The interest in knowing the exact behavior of fields at the end of the fiber has increased due to the widespread applications of the optical fiber in various systems. Studying the diffraction from fiber ends is also important for integrated optics applications, interferometric sensors and near-field fiber probes [3].…”

Fabry-Perot interferometer configuration consisting of a single mode optical fiber end coupled to an open cavity has been studied. The established fields inside the open cavity due to excited HE1, mode, transmission and reflection coefficients incorporating diffraction effects from the fiber end were formulated using the mode matching method. A semianalytical algorithm that accounts for the vector nature of the fields was developed and evaluated. Numerical simulations were verified against experimental measurements.
