Particle-in-a-frame gold nanomaterials with an interior nanogap-based sensor array for versatile analyte detection.

Published in: Chemical communications (Cambridge, England) (2021)

In this work, we studied the catalytic performance of gold nanomaterials, specifically a particle-in-a-frame nanostructure (PIAF) with interior nanogaps. Au PIAF was used to catalyse the 3,3',5,5'-tetramethylbenzidine (TMB) reaction. This array could accurately identify 7 proteins, 5 antioxidants, and 3 cell types.
