Abstract
Poly(styrene sulfonic acid)sodium stabilized Cu2−xSe nanoparticles (PSS–Cu2−xSe NPs) with localized surface plasmon resonance (LSPR) absorption centered at 980 nm can be selectively aggregated by lysozyme (Lys) through the electrostatic attraction, giving rise to a red shift of the LSPR in the near-infrared (NIR) region.
