Abstract
An array of discrete sensors disposed on a substrate, each sensor comprising a holographic support medium and a hologram disposed throughout the volume of the medium, whereby interaction with an analyte results in a variation of a property of the medium.
Claims3
A method for the production of a holographic sensor, which comprises the steps of:
- forming a holographic support medium by the photopolymerisation of a sample of polymerisable components, wherein a region of the sample is in contact with a mask containing oxygen such that polymerization is inhibited in said region;
- disposing within the support medium a holographic recording material;
- and recording a holographic image.
