“…This technique facilitates the fabrication of nanostructures with the spatial resolution down to sub 10 nm, keeping the fabrication cost and production time significantly low. Various nanostructures, fabricated using this technique, and following UV curing of polymers, were reported with limited application of the device [28][29][30] . Very few reports can be found which are related to the 3D nanostructured devices, fabricated by direct NIL technique [31][32] and their spectroscopic properties.…”

Low-profile patterned plasmonic surfaces are synergized with a broad class of silicon microstructures to greatly enhance near-field nanoscale imaging, sensing, and energy harvesting coupled with far-field free-space detection. This concept has a clear impact on several key areas of interest for the MEMS community, including but not limited to ultra-compact microsystems for sensitive detection of small number of target molecules, and “surface” devices for optical data storage, micro-imaging and displaying. In this paper, we review the current state-of-the-art in plasmonic theory as well as derive design guidance for plasmonic integration with microsystems, fabrication techniques, and selected applications in biosensing, including refractive-index based label-free biosensing, plasmonic integrated lab-on-chip systems, plasmonic near-field scanning optical microscopy and plasmonics on-chip systems for cellular imaging. This paradigm enables low-profile conformal surfaces on microdevices, rather than bulk material or coatings, which provide clear advantages for physical, chemical and biological-related sensing, imaging, and light harvesting, in addition to easier realization, enhanced flexibility, and tunability.

“…The signal detected (scattering cross-section) will have the resonant wavelength position, magnitude and bandwidth depending on the electromagnetic characteristics of the overall system "sensor-MUT". In particular, this sensor consists of gold conical nanoparticles arranged in an array configuration, deposited on a SiO 2 substrate as shown in The possibility to implement metallic cones on flat dielectric substrates is well established in literature, several kind of fabrication techniques are possible, for example: nano-imprint lithography and electron beam evaporation [33], electron beam induced deposition [34], templating approach [35] and nanotransfer printing (nTP) method [36].…”

Metallic nanoparticles play an important role in the design of sensing platforms. In this paper, a new electromagnetic study for conical metal nanoparticles, working in the Near Infrared and Visible frequency regime, is proposed. The structures consist of inclusions, arranged in an array configuration, embedded in a dielectric environment. The aim of this work is to develop new analytical models, in order to describe the nanoparticles electromagnetic behavior in terms of extinction cross-section (absorption and scattering). The closed-form formulas link the conical nanoparticles geometrical and electromagnetic parameters to their resonant frequency properties in terms of wavelength position, magnitude and bandwidth. The proposed models are compared to the numerical results and to the experimental ones, reported in literature. Good agreement is obtained. The proposed analytical formulas represent useful tools for sensing applications. For this reason, exploiting such models a new sensing platform able to detect different blood diseases is obtained. Numerical results confirm the capability of the proposed structure to be used as a sensing platform for medical diagnostics.
