Special Issue Information

Dear Colleagues,
Point-of-care (POC) diagnostics have unique advantages in terms of portability and ease of use; therefore, POC diagnostics are considered the best candidates that meet the purpose of on-site diagnostics where medical diagnostic testing needs. Especially, if high sensitive POC device can be realized, one can apply POC device more widely for medical diagnosis, virus detection, food safety and environmental monitoring, etc.
This Special Issue aims to promote exchanges of ideas and knowledge about recent POC diagnostics, focusing on materials, devices and applications.
This Special Issue includes, but is not limited to, the following:
  • Novel point-of-care (POC) materials
  • Digital microfluidics
  • High sensitive electrical devices
  • High sensitive MEMS devices
  • Novel sample preparation devices
  • Acoustic based sample separations
  • Device platform using non-invasive human samples (urine/saliva/sweat)
  • Wearable devices for POCT
  • Chemical sensing applications using POCT
  • Biosensing applications using POCT
  • Novel target marker for POCT

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.
