  • Publication number: 20200384462
    Abstract: Among other things, the present invention is related to devices and methods of sample holders that facilitate biological and chemical assays, and use of the same. Particularly, the present invention is related to an assay sample hold (also termed “card”) that comprises two plates that are movable relative to each other and that can sandwich a sample between the two plates. One objective of the present invention is to provide sample holders that are easy to separate them when the plates are stacked two plates, easy to handle by one hand while loading a sample, easy to fabricate, and/or low in cost. Another objective of the present invention is to ensure the two plates stay together when they are insert into a slot of an adaptor for analyzing the sample sandwiched between the two plates.
