Abstract: Provided herein is a method of quantitating a fungus in a plant, plant product or agricultural product. Total nucleic acids are isolated from a sample of the plant or plant product, and an asymmetric PCR amplification reaction is performed using fluorescent labeled primer pairs to obtain fluorescent labeled fungal amplicons. These amplicons are hybridized to fungus specific nucleic acid probes that are attached on a microarray support. The microarray is imaged to detect fluorescent signals from the fluorescent labeled fungal amplicons. The fluorescent signal intensity is correlated to the quantity of fungus.

Abstract: Systems and methods for low-cost point-of-care immunoassay are provided. The system comprises an emitter, two optical interference filters, a microscope slide, a photodiode detector, a circuit, and a measuring unit. The detector is placed upon the second filter, the slide, the first filter, and then the emitter. The emitter comprises non-organic light emitting diodes (LEDs) or organic light emitting diodes (OLEDs) that emits light of a first color. The slide is spotted with biofluid from a patient. Biomarkers in the biofluid is bound with immobilized fluorophores that emit light of a second color when stimulated by the light of the first color. The first and second filters band-pass the light of the first and second colors, respectively. The detector detects light of the second color. The current outputted from the detector is converted into a relatively-large output voltage by a circuit. A measuring unit measures the ramp time of the output voltage.

Abstract: The present disclosure provides a method of using a sweat sensing device to determine a kidney profile for an individual. The method includes taking concentration, ratio, and trend measurements of one or more kidney biomarkers in the individual's sweat, along with other contemporaneous device measurements to inform sweat rate, skin temperature, sweat sample pH, or other factors. The method further considers these measured values in the context of external information about the individual, and uses such information to develop a kidney function profile or a kidney injury profile indicative of the physiological state of the individual.

Abstract: The present disclosure provides a method of using a wearable biofluid sensing device to develop a cytokine profile for an individual. The method includes taking concentration, ratio, and trend measurements of one or more cytokines in the individual's sweat, along with other contemporaneous device measurements to inform sweat rate, skin temperature, sweat sample pH, or other factors. The method further considers these measured values in the context of external information about the individual, and uses such information to develop (1) a baseline cytokine profile characterizing the individual's healthy cytokine levels, or (2) an inflammation profile for a physiological condition, which characterizes the expected cytokine levels for a physiological condition. Also included is a method to use a biofluid sensing device to determine whether an individual has a physiological condition by comparing device measurements to the baseline profile and inflammation profile. Results are then communicated to a device user.

Abstract: The disclosed invention includes methods to employ wearable biosensing devices to accomplish the following: 1) screen for the presence of a disease or infection, including pre-symptomatic detection, and determination of the type (e.g., viral, bacterial, or fungal) of disease or infection present; 2) confirm the antigen and monitor the progress of an active infection; and 3) monitor the efficacy of a treatment program for a disease or infection. Such methods rely on the detection, in sweat or other biofluids, of proteins, nucleotides, DNA polymerases, proteases, group-specific antigens, antibodies, cytokines, or other molecules, that are produced by the body as part of the innate or adaptive immune responses to an infectious agent, or the infectious agent itself, its products, or derivatives. Some embodiments comprise a method of using such a biosensing device as a biosentinel against biological threats.

Abstract: The disclosed invention addresses an unmet need of biofluid analysis by utilizing the presence of certain nucleotides, e.g., microDNA, eccDNA, DNA fragments, microRNA, RNA fragments, and peptides, in a sample biofluid, such as eccrine sweat, apocrine sweat, blood, serum, saliva or tears, to perform a number of physiological sensing functions. Specifically, the present disclosure provides: (1) a device and method of determining whether a biofluid sensing device is being worn by a specific individual based on a measurement of nucleotides in a biofluid; (2) a device and method of recognizing at least one physiological disease or condition based on nucleotide concentrations, ratios, or trends in a biofluid.
