Resonance-based sensors can be used as an advanced tool for gas sensing as they show several advantages as compared to conventional gas sensors like metal-oxide semiconductor and electro-chemical gas sensors. With the introduction of an additional metamaterial layer over the sensor, the selectivity of these sensors can be improved. These article focuses mainly on metamaterial-based split ring resonators (SRR) and complementary SRRs (CSRRs) structures used in several sensing applications.

A lithography-free method for printing optical metasurfaces with resonant laser printing can achieve metasurfaces for structural colors, optical holograms, and diffractive optical elements, with an energy consumption of less than 1 nanojoule and a print time down to 1 nanosecond per dot. The performance of this ink-free laser color printing with a resolution of more than 100 000 dpi by far exceeds the output of conventional laser printers. The nanoscale structures made on a multi-layer film are robust and typically could last longer than most inks or pigments.

With a new approach, that brings us closer to the commercial application of 3D color holograms, scientists have developed the concept of a virtual 3D color object consisting of colorful focal spots at discrete heights in the out-of-plane dimension above the surface of a print - something they dubbed 'optical fireworks'. Unlike previous 3D color holograms, this color-filtering microlens-based displays realize multicolor and multifocal simultaneously in the form of bright colorful focal spots floating above the prints.
