Colorimetric assay based on iron(iii) ions triggering the aggregation of a poly(tannic acid) coated Au nanocomposite for carbonic anhydrase II detection

Abstract

Herein, several components including mesoporous silica nanoparticles (MSNs) as a reservoir, iron (III) ion to trigger color change, gold nanoparticle (AuNP) as an imaging agent and tannic acid (TA) to...
