Acid-disassembly of Au NCs observed by OCT and DvOCT. Images of acid-disassembling Au NCs in droplets (3 μL) obtained using SD-OCT (a, b) and DvOCT (c, d) after incubation in DI water or pH 5.0 acetate buffer at 37°C for 2 h. Fast and slow moving particles (c, d) were color-coded with red and green, respectively, and further quantitatively analyzed (e)
