Painless Biosensing for Non‐Invasive Health Monitoring: Advances, Platforms and Future Directions
ABSTRACT Non‐invasive biosensing has expanded blood‐based diagnostics into a growing set of accessible peripheral biofluids, yet most existing reviews remain confined to sweat, tears, saliva and urine, and treat the underlying literature descriptively rather than critically. Here, we present a review that extends this scope to include interstitial fluid and breath/exhaled breath condensate, two increasingly important non‐invasive matrices that have been largely absent from prior synthesis, and that explicitly disti …
