Nanoconfinement-Driven Solid-State Ratiometric Fluorescent Aptasensor for 17β-Estradiol Detection in Complex Matrices
Precise quantitative monitoring of 17β-estradiol (E2) is important for reproductive management in precision livestock farming. However, E2 determination in complex biological matrices remains challenging because of matrix-derived background and signal variability. Here, we developed a nanoconfinement-assisted solid-sta...
