Abstract: One aspect of the present invention is to provide the device and methods for performing an assay that uses the multiplexing of sample thicknesses on the same plate. The sample thickness multiplexing can offer many information that are unavailable in using a single sample thickness.

Abstract: Among other things, the present invention is related to devices and methods of performing biological and chemical assays, such as but not limited to immunoassays and nucleic assay acid, particularly the homogeneous assay that does not use the step of wash and that is fast (e.g. 60 seconds from dropping a sample to displaying results).

Abstract: A shingled photovoltaic module with bypass diodes, includes four regions. Each region includes a plurality of cell strings consisting of crystalline silicon cells or crystalline silicon slice cells; the cell strings in the each region are connected in parallel with each other, and circuits between the regions are connected in series with each other; a first region and a second region are protected by one bypass diode, and a third region and a fourth region are protected by another bypass diode; the bypass diodes are positioned in a central part of the module; and positive electrode and negative electrode cables of the module are led out from a junction box which is located on a back side of the module and is close to an edge of the module.

Abstract: The present invention provides, among other thing, devices and methods for simple, fast, and sensitive assaying, including imaging.

Abstract: Among other thing, the present invention provides solution to the problem, particularly, the present invention certain surfaces and certain sample holder to improve the sensitivity, speed, and easy-to-use of an optical signal based assays, such as colorimetric assays or fluorescence assays.

Abstract: Among other things, the present invention is related to devices and methods for improving optical analysis of a thin layer of a sample sandwiched between containing between two plates.

Abstract: Among other things, the present invention is related to devices and methods of performing biological and chemical assays, particularly an easy sample manipulation and/or a rapid change or a rapid thermal cycling of a sample temperature is needed (e.g. Polymerase Chain Reaction (PCR) for amplifying nucleic acids).

Abstract: The present invention relates to the methods, devices, and systems that make bio/chemical sensing (including, not limited to, immunoassay, nucleic assay, electrolyte analysis, etc.) faster, more sensitive, less steps, easy to perform, smaller amount of samples required, less or reduced (or no) needs for professional assistance, and/or lower cost, than many current sensing methods and devices. The present invention also allow a test performed by a smartphone.

Abstract: The present invention provides, among other things, devices, methods and applications of collecting, preserving, transporting, and analyzing tiny body fluids which have targeted biomarkers.

Abstract: Among other things, the present invention is related to devices and methods of performing biological and chemical assays, devices and methods of performing a biological and chemical extraction from a liquid, and performing assays, such as but not limited to immunoassays and nucleic acid assays.

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.
