Formation mechanism of the Pt NCs aggregates. (a) Schematic illustration showing various porous hollow luminescent protein-templated platinum nanostructures synthesized via a combination of aggregation-induced emission, oriented attachment and Ostwald ripening mechanisms. (b) X-ray photoelectron spectrum of Pt 4 f for the Hb/Pt NCs obtained at three interval times of reaction (first day, middle day and last day) at 37 °C.
