A magneto-optical biochip for rapid assay based on the Cotton–Mouton effect of γ-Fe2O3@Au core/shell nanoparticles
Highlights 1. We developed a biochip for rapid assay based on the magneto-optical Cotton–Mouton (CM) effect of γ-Fe2O3@Au core/shell magnetic nanoparticles. 2. The easy and quick assay for detection of the spike glycoprotein S of SARS-CoV-2 was demonstrated, and whole process takes approximately 50 ...
