Biosensors for Precision Health Monitoring and Early Diagnosis
Precision Health reimagines medicine to focus on predicting, preventing, and curing disease precisely. Marrying two seemingly different approaches—high-tech and high-touch—this vision tailors health care to the unique biology and life circumstances of each individual, with an emphasis on catching disease before it strikes. Precision Health represents a fundamental shift to more proactive and personalized care that empowers people to lead healthy lives.
The evolution of photoelectrochemical (PEC) bioanalysis has resulted in substantial progress in its analytical performance and biodetection applications. PEC sensor represents a unique means for chemical and biological detection, with foci of optimizing semiconductor composition and electronic structures, surface functionalization layers, and chemical detection methods. Here, I have briefly discussed my recent developments of nanowire‐based PEC sensing, with particular emphasis on three main detection mechanisms and corresponding examples. I have also demonstrated the use of the PEC sensing of real‐time molecular reaction kinetic measurements, as well as direct interfacing of living cells and probing of cellular functions. My work will serve as a useful source to inform the interested audience of the latest developments and applications in the field of PEC bioanalysis.
