a Schematic illustration of antigen (cTnI/CK-MB) detection on pGold chip using a sandwich assay. b Extinction spectra of pGold chip (red line), glass (black line), and sGold chip (blue line) overlaid with the excitation and emission (yellow shaded area) regions of IR800 dye. c Top-view SEM of pGold chip (n ≥ 3 randomly selected). d Digital image of two bulk reaction wells and side-view SEM of gold islands on pGold chip. e Digital image of two antibody-printed reaction wells and side-view SEM of capture antibodies on pGold chip. f Top-view SEM of capture antibodies on pGold chip (n ≥ 3 randomly selected). Insets of (c) and (f) were the zoomed SEM images. Source data are provided as a Source Data file.
