PHB/ErGO electrochemical immunosensor for H5N1 serology: Insights into selectivity and inflammation-mediated matrix effects.
Reliable electrochemical immunosensing in biological samples requires not only selective molecular recognition but also preservation of analytical performance in complex matrices. Here, a label-free electrochemical immunosensor based on electrochemically reduced graphene oxide (ErGO) and polyhydroxybutyrate (PHB) nanop...
