Design of a high figure of merit subwavelength grating based plasmonic sensor for detection of DNA hybridization

An electricity-fluorescence double-checking biosensor based on graphene for detection of binding kinetics of DNA hybridization

“…The detection of binding kinetics of DNA hybridization plays an important role in the diagnosis of diseases, [1][2][3][4][5] treatment of pathogen infections 3 and forensic tests. 4,5 To date, a variety of methods have been studied for the detection of DNA hybridization which mainly include optical [6][7][8] and electrochemical methods. [9][10][11] Among the optical methods, label-free surface plasmon resonance (SPR) is the standard tool for DNA binding detection.…”

Beam Tailoring Devices Using Transmission-Type Subwavelength Grating

“…Moreover, most previous studies on metamaterials have lacked rigorous theoretical calculations and derivations. Subwavelength gratings (SWGs), in part, can be considered as subwavelength-scale photonic crystals and are emerging as an enabling technology for implementing compact, high-performance photonic integrated devices and circuits [6,7], including reflectors [8], directional couplers [9], filters [10], splitters [11], sensors [12], and modulators [13], among others. Moreover, certain subwavelength gratings with novel surface structures can greatly improve device performance [14].…”
