Holographic sensors are analytical devices that systematically diffract narrow-band light in the ultraviolet to near-infrared range for application in the detection and quantification of analytes and/or physical parameters. They can be functionalized with analyte-responsive materials to construct highly sensitive optical sensors for use in testing, where a visual readout, fast turnaround time, and reversibility are needed. Holography allows fabrication of disposable sensors that are lightweight for miniaturization and multiplexing purposes.3 Holographic sensors offer three capabilities on a single analytical device: (i) label-free analyte-responsive polymer, (ii) real-time, reversible quantification of the external stimuli, and (iii) three-dimensional visual image display.
