A wafer for carrying a biological sample includes a pair of circular discs, at least one of the discs being transparent. The wafer also includes a gap between the discs adapted to receive a biological sample. The compact circular shape of the wafer makes it particularly suited for use in a portable device in which the wafer is rotated to enable a camera to image different areas of the sample between the discs. The gap may be sized to pull a biological sample into the gap by capillary action.

The present invention relates to a wafer for carrying a biological sample, a method of assembling such a wafer, and a method of loading a sample into such a wafer.
The term “wafer” is used herein to refer to a sample carrier which may or may not have a circular periphery.
Conventional systems and methods for biological imaging usually require a microscopic setup operated by humans traversing slides in translational movements, or a very expensive technique such as spectroscopy, flow-cytometry, electrical impedance, or chemical assays. Such technologies are unaffordable for applications of high population impact. Such systems and methods also do not scale and generalise well as they require manual analysis and are based on expensive optics and often provide inaccurate or incompatible results.
FIG. 1 is a plan view of a wafer;
FIG. 2 is an isometric view of the wafer of FIG. 1;
FIG. 3 shows a gap between the discs;
FIGS. 1-3 show a wafer 1 carrying a biological sample 8. The wafer comprises an upper disc 2 and a lower disc 2. A gap 6 between the discs is adapted to receive the biological sample 8.
A circular patch of adhesive tape 4 joins the lower face of the upper disc 2 to the upper face of the lower disc 3 at the centre of the wafer 1. The discs have circular peripheries 2a, 3a at an edge of the wafer 1. The diameter of the wafer may be between 2 cm and 5 cm, for example.
The discs are spaced apart so that the gap 6 provides an annular sample chamber around the adhesive tape. The gap 6 extends from an inner periphery at the circular periphery 4a of the adhesive tape 4 to an open circular outer periphery at the edge of the wafer 1.
