Smartphone Platform Gives Early Warning for Cancer

A new platform provides visual detection analysis for lung cancer and ketosis/diabetes via different testing probes. A research team designed and prepared two high-efficiency organic ratio fluorescent nanoprobes and achieved the detection of biomarkers in exhaled breath by combining with the color recognizer of the smartphone. The portable smartphone platform is based on a single-particle dual-emission ratio fluorescent probe, which provides visual detection of isopropanol in exhaled breath. Another fluorescent sensor platform effectively captured acetone in blood and exhaled breath and warn ketosis/diabetes.
