Integrating catalytic and fluorescence quenching strategies: A nanozyme-based platform for rutin sensing in complex matrices.

Rutin is a potent antioxidant with therapeutic value in managing vascular and inflammatory conditions. Its accurate quantification is critical for pharmaceutical quality control and food safety. In this study, rutin was employed as a template to construct surface molecularly imprinted magnetic nanozymes (MIPs@FeO-CoNi).
