Intelligent point of care testing for medicine diagnosis

Abstract

Intelligent point-of-care testing (iPOCT) is a rapidly advancing technology that combines molecular detection and bio-sensing techniques to achieve instant and accurate analysis through advanced sensors and intelligent algorithms. Molecular detection technologies, such as nucleic acid isothermal amplification, biochip and microfluidics, enable rapid analysis of the chemical composition and concentration of samples, thereby determining their presence. Bio-sensing technology utilizes the recognition properties of biomolecules in conjunction with sensors to detect specific biomolecules or biological processes. iPOCT technology holds broad prospects for application in the field of healthcare and is expected to enhance detection sensitivity, accuracy, and intelligence through further development. In this review, we delineate the developmental journey of iPOCT, followed by a discussion on the principles of molecular detection and bio-sensing technology, as well as the design of iPOCT devices for health monitoring and disease diagnosis. Furthermore, we showcased illustrative examples of iPOCT applications in disease diagnosis, highlighting the integration of iPOCT technology with wearable devices and smartphones for attaining more precise and personalized diagnostic results.
