This manuscript presents a novel double c-shaped copper-based refractivity biosensor (DCSCRIB) for the recognition of cervical nucleus as well as cervical cytoplasm cells.

According to the highest value of photothermal conversion efficiency (PCE) in each bimetallic compound, three Au@Ag, Pt@Ag, and Au@Pd nanorods, with aspect ratios of 4, 4, and 5, respectively; and all with a coating thickness of 1 nm; were chosen as the best ones named “A,” “B,” and “C”.
