Randomized trial demonstrates rapid haemoglobin detection in finger-prick samples, suggesting effective POCT options.

This work aims to develop a cost-effective and efficient sensor system for haemoglobin detection in finger-prick samples.
Developed an eMIP film integrated on plasmonic optical fiber sensor chips for Hb detection.
Conducted selectivity tests against common interfering proteins like BSA and IgG.
Tested sensor performance using whole-blood samples and compared results with standard hemato-analysis.
Achieved an ultra-low detection limit of 80 fM in buffer, significantly lower than other Hb sensors.
Demonstrated high specificity for haemoglobin in presence of common interfering proteins.
Sensor performance was consistent with standard laboratory haematology analyses.

Pitruzzella et al. (2026) studied this question.
