Pyridinium porphyrins and AuNPs mediated bionetworks as SPR signal amplification tags for the ultrasensitive assay of brain natriuretic peptide.

Recent work at Shanghai University by the Chen group was published in Microchimica Acta reporting a surface plasmon resonance biosensor for the determination of brain natriuretic peptide. Detection was accomplished by binding of the peptide to an amine functionalized aptamer probe. Pyridinium porphyrin-mediated Au nanoparticle composites were used to amplify the SPR signal. Thanks for using our Fe (III) meso-tetra(N-methyl-4-pyridyl)porphine pentachloride catalog number T40322.
