Holography allows producing optical sensors for applications in the detection of clinically relevant substances. The great advantages of holographic sensors over other sensing materials is the ability to create three-dimensional images, rapid laser fabrication, and amenability to mass manufacturing at low-cost. This talk will outline the state-of-the-art holographic sensors by showing strategies in the preparation of analyte-sensitive hydrogels, discuss laser writing, and show the results from clinical trials in diabetic patients attending the Wolfson Diabetes and Endocrine Clinic (Addenbrooke’s Hospital). The talk will also demonstrate a smartphone reader app that allows interpretation of colorimetric tests at point-of-care. The presentation will be concluded with current limitations in holographic sensors and future directions will be outlined.
