The advantages of using a broadband source for biosensing applications


The University of British Columbia’s Department of Electrical and Computer Engineering have explored a new way to carry out biosensing applications. Rather than the typical method of using Ge-based photodetectors and tunable lasers, UBC advocates for the benefits of using doped photoconductive heater-detectors and broadband sources. The article explains the potential to achieve low-cost, complete lab-on-a-chip sensing systems by leveraging mature CMOS fabs, and how these photonic-based devices excel at label-free detection.
