Abstract

Abstract Smartphone is emerging as a portable analytical biosensing platform in many point-of-care (POC) applications such as disease diagnostics, environmental monitoring, and food toxin screening. With the recent advancement of imaging technologies on the smartphone, the manual control of acquisition settings (e.g., exposure time, frame rate, focusing distance, etc.) has already been expanded from the photo to the video capturing mode. In modern smartphone models, high frame rate (above 100 fps) can be achieved to bring in a new temporal dimension to the smartphone-supported POC tests by recording high-definition videos. This opens up a new analytical method defined as smartphone videoscopy. In this review, the recent development of smartphone videoscopy is summarized based on different POC applications. Representative examples of smartphone videoscopy systems and how these time-dependent measurements could open up new opportunities for POC diagnostics are discussed in detail. The advances demonstrated so far illustrate the promising future of smartphone videoscopy in biosensing, POC diagnostics, and time-resolved analysis in general.

智能手机视像:生物传感的最新进展和机遇

智能手机正在成为一种便携式分析生物传感平台，在许多护理点(POC)应用中，如疾病诊断、环境监测和食物毒素筛选。随着近年来智能手机成像技术的进步，手动控制采集设置(如曝光时间、帧率、对焦距离等)已经从照片扩展到视频捕捉模式。在现代智能手机模型中，可以实现高帧率(超过100 fps)，通过录制高清视频为智能手机支持的POC测试带来新的时间维度。这开辟了一种新的分析方法，被定义为智能手机视屏。本文就智能手机视屏技术在不同领域的应用进行综述。详细讨论了智能手机视频检查系统的代表性示例以及这些随时间变化的测量如何为POC诊断开辟新的机会。到目前为止所取得的进展表明，智能手机视频检查在生物传感、POC诊断和时间分辨分析方面的前景广阔。
