Abstract
En 中文
The extensive use of smartphones with point-of-care (POC) applications has boosted the development of what is commonly known as Healthcare 4.0. The ability to track biomarker parameters has become a critical part of monitoring the progression of certain diseases, with a potential application in a large population group. In this line, this work presents a multianalyte quick response (QR) colorimetric code for real-time measurement of glucose and lactate samples using smartphones. The colorimetric QR code contains both QR static data and dynamic information from sample analyses. Two correction methods are applied in order to compensate for the variation in the surrounding conditions during biomarker tracking. Glucose and lactate recovery between 91 and 117% was found in assays including sweat and serum samples through smartphone readout.
