| Abstract: | Chitin nanowhiskers (ChNWs) hybridized with the densely adsorbed gold nanoclusters (AuNCs) were facilely prepared by a simple mixing of aqueous suspensions of ChNWs and AuNCs. Adsorption of AuNCs on the ChNW surface was confirmed by transmission electron microscopy and scanning electron microscopy with energy dispersive X‐ray spectroscopy. The amounts of adsorbed AuNCs measured by thermogravimetry and combustion using a muffle furnace were in good agreement. While the amount of adsorbed AuNCs increased with AuNCs/ChNWs feeding ratio, we found only a weak dependence of adsorbed AuNC amount on the surface amino group content of ChNWs controlled by pre‐deacetylation of the starting chitin.
