Abstract: The present invention is related to the field of bio/chemical sampling, sensing, assays and applications. Particularly, the present invention is related to how to make the sampling/sensing/assay become simple to use, fast to results, highly sensitive, easy to use, using tiny sample volume (e.g. 0.5 uL or less), operated by a person without any professionals, reading by mobile-phone, or low cost, or a combination of them.

Abstract: Provided herein is a method and device for performing a homogeneous nucleic acid detection assay. The device can contain a pair of plates where one of the plates comprises (i) surface amplification surface; and (ii) target-specific nucleic acid probes that are immobilized on said amplification surface and that specifically binds to a part of the target nucleic acid; and the second plate comprises a sample contact area comprising a reagent storage site that comprises target-specific nucleic acid detection agents that specifically binds to another part of the target nucleic acid. In some embodiments, the device can be read without a washing unbound label from the surface of the device.

Abstract: The present invention provides devices, systems, and methods for rapid and easy-to-use in sample thermal cycling or temperature changes for the facilitation of reactions such as but not limited to PCR.

Abstract: Disclosed is a method for correlating a biomarker in a non-blood bodily fluid with the same biomarker in the blood of an individual, including: measuring, in a first period in time, the biomarker in non-blood bodily fluid and measuring the same biomarker in the blood of the same individual to establish an R ratio of [NBBF1]/[BB1], where [NBBF1] is the biomarker concentration in non-blood bodily fluid in the first period in time, and [BB1] is the biomarker concentration in the blood in the first period in time; storing the ratio in a memory; measuring, in a second period in time, the biomarker in non-blood bodily fluid to determine [NBBF2], where [NBBF2] is the biomarker concentration in the non-blood bodily fluid in the second period in time; and correlating the measured [NBBF2] with the R ratio to generate a correlated [BB2] biomarker concentration in the blood of the individual in the second period in time.

Abstract: The present invention is related to correct the errors in instruments, operation, and others using intelligent monitoring structures and machine learning, and others.

Abstract: Among other things, the present invention provides devices and methods that stain a sample simply (e.g. one step) and quickly (e.g. <60 seconds), image it without wash, and generate, by a machine learning algorithm, a final image similar to a standard staining with wash.
