Smartphone-Based Cell Detection
The smartphone integrated high-resolution complementary metal-oxide semiconductor (CMOS) sensors have been widely exploited to detect optical signals, relying on colorimetric, fluorescent (FL), and bio-chemiluminescent detections. In the last 5 years, there has been an exponential increase in the publications on the use of smartphones as stand-alone bioanalytical devices. Conversely, the use of smartphones to detect cells and cell biosensors has been seldomly explored. In this chapter, we will review the smartphone potential as portable detector, and we will provide an overview on the state-of-the-art of using smartphones to detect cells and cell biosensors. Major research trends, open issues, and limitations are also addressed to provide the reader a glance on this challenging research trend.
