  • Patent number: 11378573
    Abstract: A method of analyzing a biological sample using an analyzer and an assay. The method comprises providing the assay for producing the signal. The assay has two or more predetermined number of components. Each of the predetermined components has a distinct relation between the intensive property and the signal. The method further comprises providing calibration samples with known values for the intensive property and measuring a calibration signal for each of the calibration samples. The method further comprises determining a calibration by fitting a calibration function to the calibration signal for each of the calibration samples and the known values for the intensive property. The calibration function is equivalent to a constant plus an exponential decay term for each of the predetermined number of components. The method further comprises measuring the signal of the sample using the analyzer and the assay, and calculating the intensive property using the calibration.

  • Patent number: 11364494
    Abstract: The invention relates to an array type paper chip for 2019-nCoV virus high-throughput detection and a manufacturing method of the array type paper chip. The array type paper chip comprises a glass substrate layer, a paper unit layer and a cell grid layer which are arranged in sequence from bottom to top, wherein the grid layer comprises N circular paper detection units with a diameter R being arranged in the form of an array; and the unit grids of the unit grid layer are in one-to-one correspondence to the paper detection units to separate the paper detection units. The array type paper chip is simple in structure, the manufacturing process is simple and stable, the finished products are stable, requirements on the processing environment and conditions are very low, and processing equipment is low in price. Moreover, the processing process does not revolve any chemical reagent, and therefore, the method is more environmentally friendly than methods such as ultraviolet lithography.
