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

Work from the Chen group at Shanghai University published in Microchimica Acta described the development of a surface plasmon resonance (SPR) sensor using pyridinium porphyrin-mediated gold nanoparticle composites to amplify SPR signal when detecting B-type natriuretic peptide (BNP). The determination range for the sensor was shown to be broad and the experimental execution simple and easily performed. Thanks for using our Fe(III) meso-Tetra (N-Methyl-4-Pyridyl) porphine pentachloride, T40322
