Highly Sensitive Colorimetric Assay for Determining Fe(3+) Based on Gold Nanoparticles Conjugated with Glycol Chitosan

A highly sensitive and simple colorimetric assay for the detection of Fe(3+) ions was developed using gold nanoparticles (AuNPs) conjugated with glycol chitosan (GC). The Fe(3+) ion coordinates with the oxygen atoms of GC in a hexadentate manner (O-Fe(3+)-O), decreasing the interparticle distance an...
