Visual detection of glucose based on quantum dots aerogel in microfluidic chips

Abstract

In this study, we demonstrated a new optical glucose microfluidic sensor based on quantum dots (QDs) aerogels and glucose oxidase (GOx) for rapid, low-cost and quantitative detection of glucose in human urine and serum. The combination of QDs–GOx based aerogels and microfluidic chips was first investigated and compared with other sensors, providing new insights into the design of a microfluidic system toward the detection of glucose.
