1. A method of analysis of a sample, the method comprising:
providing a sample holder having an upper surface and a lower surface, the upper surface having a plasmonic layer associated therewith, the plasmonic layer including a periodic array of sub-micron structures;
applying the sample to the upper surface of the sample holder;
illuminating the sample with light so that said light interacts with the sample and sample holder;
forming an image using said light, after interaction with said sample and sample holder, wherein at least one localised structural property of the sample is visible in the image based on a colour of the received light; and
using the image formed to control a subsequent analysis process.
