  • Patent number: 11883824
    Abstract: Disclosure relates to a device and a method of using the device for conducting biological and chemical assays on a sample. The device includes two plates. The first plate includes at least a first and a second sample contact areas on its inner surface. Each sample contact area includes spacers having a bottom end fixed on the inner surface and a top end that is distal to the inner surface. The spacers in the first sample contact area differ in height from those in the second sample contact area. The first and second sample contact areas are disposed at different depths along the inner surface of the first plate, so that the top ends of the spacers are aligned on the same flat plane. The method includes depositing the sample onto the sample contact areas, compressing the sample into a thin layer, and analyzing the sample.
