Paper Abstract

In this work, we investigated photonic crystal (PhC) based double nanocavity resonator biosensor. The sensor performance has confirmed by both sucrose and prostate specific antigen (PSA, a protein biomarker associated with prostate cancer). The device sensitivity and quality factor in sucrose solution are 1571 nm/RIU (Refractive Index Unit) and 2×105 respectively. By using special antigen-antibody reaction, we successfully detected PSA concentration as low as 0.5 ng/mL.
