报告内容简介

Current guidelines for healthcare emphasize rapid testing and reporting, which can be better satisfied by point-of-care (POC) diagnostic tools rather than centralized medical laboratories using automated multi-analyte analyzers by trained professionals. With POC testing, the turn-around time is significantly reduced, leading to earlier decision making and more efficient medical treatment. At present, POC protocols are predominantly based on rapid-test immunoassay strips/cassettes that combine gold nanoparticles for colorimetric (mostly qualitative) detection and flow-through systems for sample delivery. Mobile electronics (particularly smartphones) provides a promising alternative to today’s POC testing instrumentation; in this regard, we have recently explored the feasibility of using smartphones in combination with customized mobile apps as the detection platform for quantitative colorimetric analysis. Beyond biomedical applications, these POC analytical tools can be beneficial to on-site food safety, environmental monitoring, and inclusive chemical education.
