“…This sensing mechanism is based on the change of resistivity (ΔR) of the film by adsorbing the analyte to the chemically sensitive Au NP film, which exhibits high sensitivity for both liquid and gas detections. , It is noteworthy that the selection of thiols on the NP surface plays an important role in the sensitivity and selectivity of Au NP based chemiresistors, which have been widely exercised to optimize the properties of chemiresistors. − …”

The noble metal nanoparticle has been widely utilized as a plasmonic unit to enhance biosensors, by leveraging its electric and/or optical properties. Integrated with the “flexible” feature, it further enables opportunities in developing healthcare products in a conformal and adaptive fashion, such as wrist pulse tracers, body temperature trackers, blood glucose monitors, etc. In this work, we present a holistic review of the recent advance of flexible plasmonic biosensors for the healthcare sector. The technical spectrum broadly covers the design and selection of a flexible substrate, the process to integrate flexible and plasmonic units, the exploration of different types of flexible plasmonic biosensors to monitor human temperature, blood glucose, ions, gas, and motion indicators, as well as their applications for surface-enhanced Raman scattering (SERS) and colorimetric detections. Their fundamental working principles and structural innovations are scoped and summarized. The challenges and prospects are articulated regarding the critical importance for continued progress of flexible plasmonic biosensors to improve living quality.
