“…The plasmonic structure presented in [121] consists of gold bowtie nanoantenna arrays fabricated on SiO 2 pillars which can be employed as a direct laser writing and plasmonic optical tweezers. It is worth noting that a combination of traditional MEMS with plasmonic sensing can be realized [144–149]…”

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.

A Localized Surface Plasmon Resonance (LSPR) biosensor based on a subwavelength grating structure is studied numerically for detection of bulk refractive change of aqueous environments such as biological buffer solutions. A high grating thickness of 40nm and a short grating period of 50nm are selected to evaluate numerically the effect of the other grating structural parameter i.e. fill factor (f.f) on the sensor performance including dispersion curve, sensitivity, FWHM, MRR and resonance angle. Evaluation shows that corresponding wavelength to the effective resonance of surface plasmons which locating in near infrared (NIR) wavelength range is displaced with f.f value. Also, as shown for some f.f values sensitivity is enhanced slightly whereas FWHM, MRR and resonance angle is increased. Thus with adjusting both of operating wavelength and f.f value, it is possible to get a better performance for the plasmonic sensor.

“…The most widely known application of SPPs is sensing of chemical and biological molecules and real-time monitoring of bio-molecular interactions [62] on a metal surface, where a change in the refractive index of the surrounding medium shifts the minimum in the reflection spectrum. Recently, a microfabricated silicon SPR sensor combining a Si prism and an optical grating has been developed for near-IR wavelengths [63] that might act as a miniaturized one-chip SPR sensor for point-of-care use.…”
