  • Patent number: 11231369
    Abstract: A single unit, handheld field portable apparatus and method for analyzing Ochratoxin A (OTA) in rice quality monitoring, based on fluorescence signal output. Aliquots may be analyzed by adding at least one or more reagents to the sample aliquot that reacts selectively with an analyte contained therein. The reaction product, which is selective for the analyte of interest and proportional to its concentration, is measured with an appropriate detector. This enables simple and accurate testing of samples using time honored wet-chemical analysis method in microliter volume regimes while producing remarkably small volumes of waste. The device includes a multipurpose controller board for processing and analysis purpose, a camera which is integrated with the controller, a resistive touch liquid crystal display to view the results, a light emitting diode to emit the UV light, and a power bank. The device may operate using a touch display.

  • Patent number: 10684277
    Abstract: A method for colorimetric detection of cholesterol in a sample is disclosed. The method includes adding beta-cyclodextrin and cholesterol to a phenolphthalein indicator solution in the presence of a phosphate buffer solution to create a solution medium and quantifying the cholesterol as a function of a complexed beta-cyclodextrin in the solution medium.
