| 摘要 |
The invention is directed to a novel enzymatic analytical membrane, a lateral flow enzymatic detection method, and analytical device incorporating same. The invention is useful for rapidly enzymatically determining the presence of one or more analytes in small volumes of sample. The invention provides an enzymatic analytical membrane for detecting the presence of one or more small-molecule analytes in a biological sample where the membrane comprises a receiving zone; a separation zone and a signal zone, at least one of the zones comprising one or more enzymes for converting the analytes into a form detectable by reaction with a chromogenic agent present in the signal zone and wherein the membrane horizontally receives sample at the receiving zone, and the sample continues via lateral flow through the receiving zone, separation zone and signal zone where a visible color change is formed indicating the presence of the analyte. |
