Nuts and Bolts of Modern Biosensing Technology: Smart Health Diagnostic Devices

Point-of-care (PoC) sensing technologies are one of the most significant analytical tools for the timely prevention and management of modern healthcare. Miniaturized, high-throughput, convenient, and speedy analysis systems represent breakthroughs in the field of modern biosensors and bioelectronics, particularly in the healthcare sector. This chapter introduces working elements and relevant principles when establishing innovative biosensors. In addition to traditional PoC instrumentations, this chapter also draws attention to technological strategies for miniaturizing devices. The state-of-the-art integrated sensing platforms, particularly wearable bioelectronics, are discussed. We also include a discussion of representative examples in their respective applications and their future directions to evolve conventional biosensing tools in biomedical analysis.
