Abstract

This research introduces a novel label-free graphene oxide-coated dual-peak long-period grating sensor for measuring protein concentrations. It achieves high sensitivity (22 nm/(g/mL)) and a low limit of detection (0.9 µg/mL), demonstrating extremely high potential for fiber optic biosensor development.
