Explanation:
⏩A surface-enhanced Raman scattering (SERS)-based sensor for the determination of theophylline (THO) has been developed by imprinting the target molecules on the surface of silver nanoparticles.
⏩The desired recognition sites are generated after template removal and homogeneous distribution on the silver nanoparticles that have been incorporated within polymer matrix by the in situreduction of theophylline-silver complexes, providing molecular recognition ability and SERS active surfaces.
