Detection of plasmonic resonance peak shifts of nano-structured metamaterials is a promising method for sensing bio-chemical binding events. Although the concept is widely demonstrated in the laboratory environment using surface nanostructures machined at low-throughput and high-costs, practical solutions for high-volume production of an integrated sensing device are very limited. We present a concept of an integrated architecture that combines a thin layer of plasmonic nanohole sensing arrays, organic light-emitting diode illumination source, and microfluidic chip, for point-of-care, field, or lab applications. We discuss the fabrication of the sensor components. In particular, we present the improved fabrication of master nano-structure replication stamps, and demonstrate outstanding results for producing singular sheets or scale up to roll-toroll embossing of nanohole arrays on a 2000 ft production roll. We further demonstrate that nanohole arrays embossed on flexible polyethylene terephthalate plastic sheets, when coated with 100 nm thin Au metal film, are capable of generating average plasmonic resonance shifts of 180 nm refractive index unit. Hence, we report the extraordinary transmission and plasmonic resonance shifts of nanohole arrays fabricated on roll-to-roll plastic sheets for the very first time. Our results show that the embossed nano-structures on plastic are suitable as sensor elements in our proposed integrated sensor architecture, and a promising technology for low-cost disposable applications.

“…Integration efforts to date have largely been in concert with sensor developments and it is difficult to separate them entirely. A recent review discusses nanohole arrays as combined optofluidic (optical and fluidic) elements [224]. In this Section, an overview of the most notable integration advances to date is provided, as well as some areas for future efforts.…”

Extraordinary optical transmission through an array of holes in a metal film was reported by Ebbesen and coworkers in 1998. Since that work there has been abundant research activity aimed at understanding the physics and at the development of the many applications associated with this phenomenon, hence the topic of this review. The study of hole-arrays in a metal is not new -theoretical contributions on a small-hole array date back to Lord Rayleigh's description of Wood's anomaly in 1907 and there has been considerable research on metal meshes and holearrays since 1962. Bethe's theory, adapted to treat hole-arrays, is the simplest theoretical description of the transmission resonance. Following a description of this basic theory, we present the research on the additional effects from variations in real metal properties at different wavelengths, film thickness, holeshape and lattice configuration. The many promising applications being developed using hole-arrays are examined, including polarization control, filtering, switching, nonlinear optics, surface plasmon resonance sensing, surface-enhanced fluorescence, surface-enhanced Raman scattering, absorption spectroscopy, and quantum interactions. Finally, the various approaches, developments in hole-array fabrication, and integration of hole-arrays into devices are described.

“…Among artificial nanostructures, nanohole arrays exhibit many interesting features in terms of nonlinear optics 1,[9][10][11][12][13] . Airola et al showed an enhancement of the transmitted second harmonic generation (SHG) signal in a periodic circular nanohole arrays due to the increased transmission of the incident light.…”

We observed rotational anisotropy of optical second harmonic generation (SHG) from V-shaped chromium nanohole arrays with 150 nm arm-length, 50 nm width, 360 nm periodicity, 120 o apex angle, and an area of 100 µm 2 , fabricated by electron beam lithography. Phenomenological analysis indicated that the effective nonlinear susceptibility element χ ଷଵଷ (ଶ) had a characteristic contribution to the observed anisotropic SHG intensity patterns. Here coordinate 1 is in the direction of the tip of V shapes in the substrate plane, and 3 indicates the direction perpendicular to the sample surface. The SHG intensity for the S-polarized output light was very weak, probably due to cancellation effect by the image dipoles created at the metal-air boundary. The possible origin of the observed nonlinearity was discussed according to the susceptibility elements obtained.2
