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 functionalised 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. 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. Their potential applications range from in vitro diagnostics to optical security devices.

The aim of this project is to develop a nanofabrication method to produce holographic nanostructures in hydrogel films by combining laser interference lithography and silver halide chemistry in a cost-effective and rapid process. The Bragg stacks will consist of silver bromide nanocrystal multilayers. Upon broadband light illumination, the Bragg stacks diffract a narrow-band peak. To demonstrate the utility of this method, the Bragg stacks will be functionalised with analyte-sensitive molecules. The developed Bragg stacks may have application in portable, wearable, and implantable real-time medical diagnostics at point-of-care settings.

The successful student will form part of a multidisciplinary team and will be supervised by Dr. Ali K. Yetisen based in the Institute of Translational Medicine ( and the School of Chemical Engineering at the University of Birmingham.
