Point-of-need detection with smartphone

Abstract There is an increasing need in decentralized high-performance analytical testing in many fields, including human healthcare, environmental, food and water monitoring, to name a few. High-performance testing has mostly remained so far limited to bulky and expensive analytical equipment in centralized labs. Smartphone are able to break that paradigm by providing a quantitation equipment (e.g. a smartphone camera) attached to portable digital platform. This chapter provides an overview on the opportunities and challenges for smartphone-based testing in modern point-of-need applications.
