    Abstract: Probes with novel material properties and geometric confined curved tip shapes have been developed as part of cantilevered probes for scanning apertureless near-field microscopy. They produce enhanced resolution for various modalities of combined operation with optical phenomena both linear phenomena such as Raman spectroscopy, absorption, fluorescence etc and non-linear microscopies. This novel probe operates as a sensitive AFM probe with combined capabilities for enhancement of the various modalities noted above. The probes are configured to be optimized for their combined optical properties and their material properties to permit both enhanced fields and quantum state formation with the close approach of the tip to the sample. The local enhancement increases the lateral (X, Y) and axial (Z) resolution of these optical processes without the need for an apertured probe for near-field-field effects thus providing apertureless near-field optical imaging of various modalities.

    Abstract: A near- field optic (6) has a high refractive index waveguide (22) with a planar far field facet (14, 32) more than half of a wavelength across for coupling propagating light and a near field facet with the near field zone (28) of the waveguide supporting only the fundamental optical mode in each polarization. A tapered waveguide section (8) extends from the near field facet to transform the fundamental optical mode. A cantilever (24) supports the tapered waveguide section.

    Abstract: Silicon nanowires grown by e.g. the vapor-liquid-solid (VLS) mechanism with gold as the catalyst show gold caps atop -20 nm - 500 nm in diameter with an almost ideal half- spherical shape. These gold caps are extremely well suited to exploit the tip- or surface enhanced Raman effects. Attaching a nanowire with gold cap to an AFM-tip the signal enhancement by the gold nanoparticle can be used to spatially resolve a Raman-signal. Using an ensemble of nanowires as a SERS- template, that grow self- organized, bottom-up on a silicon substrate, highly sensitive signal enhanced Raman spectroscopy is feasible of all materials that show a characteristic Raman signature. A combination of a nanowire-based TERS-Probe and a nanowire-based SERS-substrate promises optimized signal enhancement so that the detection of even single molecules (e.g. of explosives, poisonous gases,...) or single bacteria, DNA strands, and other soft matter is in reach. Potential applications of this novel nanowire based technical SERS- and/or TERS solution are widespread and lie in the fields of bio-medical and life-sciences as well as security and in the field of solid state research e.g. in silicon technology where the detection of materials composition, doping, orientation and lattice strain can be probed by Raman spectroscopy, now using TERS with the spatial resolution of the nanowire based AFM-tip.
