†λg is the guided wavelength in the structure. ††20 MHz and 60 MHz shifts in resonance frequency are without and with binding. DSRR represents a double split-ring resonator. †††20 MHz and 30 MHz shifts in resonance frequency are relative to anticortisol- and antiprostate-specific antigen, respectively. SRR represents a split-ring resonator. ††††Mainly proposed as a dielectric characterization sensor, and different chemicals/particles are analyzed; however, utilization of this sensor as a biosensing device is also mentioned/suggested by the corresponding authors. †††††20 MHz and 170 MHz shifts in resonance frequency are relative to the PBS and empty microwell, respectively. |
