A smartphone takes a digital image of the paper microfluidic chip, after a red wine sample filled the entire 8 channels (each pre-loaded with a different chemical dye). The PCA score plot shows good statistical difference among the 6 red wine samples, where PC1 corresponded to the sweetness and PC2 to the bodyness of a red wine. The PCA model was validated with an additional 4 red wine samples from a different manufacturer.

In this paper, microfluidic chips supply a miniature platform for aptamer biosensor in thrombin detection. The aptamer biosensor was integrated to the microfluidic chip as a recognition element for thrombin detection. Experimental results showed that the aptamer biosensor in microfluidic chip was able to realize the function for human thrombin detection.

Titration Study

Food safety and access to systematic approaches for ensuring detection of food hazards is an important issue in most developing countries. With the arrival of paper-based analytical devices (µPADs) as a promising, rapid, easy-to-use, and low-cost analytical tool, we demonstrated a simple microfluidic-based titration study for the analysis of packaged fruit juices. Similar, to the titration experiments using traditional glassware in chemistry laboratories, in this study the titration experiments were developed using paper microfluidics for the analysis of several analytes such as pH, vitamin C, sugars, and preservatives present in the packaged fruit juices. The allergen found commonly in dairy based mixtures and the non-pathogenic biochemical component responsible for food spoilage in cider based fruit juices were also determined. The results obtained using paper microfluidics were compared with those obtained using a conventional spectrophotometric technique. Finally, a paper microfluidics based multiplexed sensor was developed for the analysis of common nutritional ingredients, an allergen, and a non-pathogenic byproduct present in packaged fruit juices on a single platform. Overall, the results presented in this study reveal that the proposed paper microfluidic assisted colorimetric multiplexed sensor offers a quick and reliable tool for on-spot routine analysis for food safety applications.
