A magnetic molecularly imprinted optical chemical sensor for specific recognition of trace quantities of virus.

ABSTRACT: A magnetic resonance light scattering (RLS) sensor based on the molecularly imprinted polymer (MIP) technique was developed for specific recognition of trace quantities of hepatitis A virus (HAV). Through a surface imprinting technique, the virus-magnetic-MIPs (virus-MMIPs) were prepared as the specific identification element, which was based on the effective synthesis of biomimetic polydopamine (PDA) inspired by mussels on the surface of Fe₃O₄ magnetic nanoparticles. The preparation process of the virus-magnetic-MIPs was simple and rapid under an applied magnetic field. The surface of the magnetic-MIP captured viruses through specific recognition in water, which caused changes to the particle size and shape, and subsequently resulted in changes in the intensity of th
