Abstract

The invention discloses a paper-based analysis device and a paper-based analysis method based on zinc oxide nanowire fluorescence enhancement. The device comprises a detection layer A and a sample adding layer B. The detection layer A comprises three detection areas which are used for detecting fatty acid binding protein FABP, cardiac troponin cTnI and myoglobin respectively. A sample is added tothe central area of the sample adding layer B, and then, the sample adding layer B is folded onto the detection layer A so that the sample is distributed to the three detection areas to realize simultaneous detection of fatty acid binding protein FABP, cardiac troponin cTnI and myoglobin. The paper-based analysis device and the paper-based analysis method disclosed by the invention can detect thethree myocardial markers at the same time and have high sensitivity and good selectivity for the detection of FABP, cTnI and myoglobin, and the detection limits of the three myocardial markers are 1.36ng / mL, 1.00ng / mL and 2.38ng / mL respectively.

Description

technical field

[0001] The invention relates to a paper-based analysis device and method based on zinc oxide nanowire fluorescence enhancement, in particular to a method of integrating zinc oxide nanowires on a paper base and simultaneously detecting a variety of myocardial A paper-based analysis device and method for markers belong to the technical field of paper-based analysis and detection. Background technique

[0002] Since 2007, the Whitesides research group of Harvard University started the research on paper-based analysis and detection, and used photolithography to prepare a paper-based analysis device for the detection of glucose and protein, which promoted the application of paper-based analysis technology in medicine. They also superimposed multi-layer planar paper chips, and fixed them with double-sided adhesive to make the first three-dimensional paper-based analysis device, which realized high-throughput detection of various substances, and proposed a microflui...
