Toward New Forms of Particle Sensing and Manipulation and 3D Imaging on a Smartphone for Healthcare Applications

Abstract

Close to half of the world population have smartphones, while a flagship smartphone today has been integrated with more than 20 smart components and sensors, making a smartphone a highly integrated platform that can potentially mimic the five senses of humans. Recent advancement in achieving high compactness, high performance computing, high flexibility, and multiplexed functionality in smartphones have enabled them for many cutting‐edge healthcare applications, such as single‐molecule imaging, medical diagnosis, and biosensing, which were conventionally done with bulky devices. Herein, recent advances in sensors in modern smartphones are reviewed and how they can potentially offer widespread and easy‐to‐implement solutions to emerging healthcare applications, including biosensing, point‐of‐care testing, pollution monitoring, etc., are discussed.
