Abstract

The invention discloses a mobile phone color analysis based cysteine detection method.The method includes: performing sample pretreatment to prepare a cysteine chromogenic sample solution; by means of image acquisition and image analysis, calculating pixel values of each component of the to-be-detected solution in different color spaces such as an RGB (red, green and blue) color space, an HSV (hue, saturation and value) color space and a CMYK (cyan, magenta, yellow and black) color space, and fitting a cysteine detection curve by means of least square fitting to obtain a corresponding relation between a cysteine concentration and the pixel values of each color component; calculating the cysteine concentration.By the mobile phone color analysis based cysteine detection method, quantitative cysteine detection is realized.In addition, the mobile phone color analysis based cysteine detection method has the advantages of simple operation procedures, portability and universality of devices, adaptability to real-time mobile phone monitoring and the like.

Description

technical field [0001] The invention relates to a technology for detecting cysteine, in particular to a method for detecting cysteine ​​based on mobile phone color analysis. Background technique [0002] Cysteine ​​is a common amino acid with sulfhydryl groups in organisms, and it participates in important physiological and chemical reactions in organisms. It is also a potential neurotoxin, a marker compound for certain diseases. Therefore, real-time, accurate and rapid detection of cysteine ​​content in blood samples and cells is of great significance in clinical diagnosis. At present, the reported analysis methods include electrochemical analysis, fluorescence analysis, spectrophotometry, etc., but there are cumbersome operations and complicated equipment that cannot be adapted to on-site detection. In recent years, due to their powerful computing and storage capabilities, smart mobile devices are often used as platforms for data processing and display to achieve mobile ...
