Abstract Although mussel‐inspired surface chemistry is one of the most utilized strategies for surface functionalization, its practical and/or industrial applications are rather limited, because dip coating can only treat small surface areas and is dependent on the coating vessel. Herein a mussel‐inspired, polymer‐based, multifunctional, and substrate‐independent spray coating strategy for surface modification under extremely mild conditions using mussel‐inspired polyglycerol is described. The p

provides strong underwater adhesion. However, the biological processing and biochemical composition underlying its adhesive remain largely unknown. Here, we identify a nanocondensate-based transport system in which halogenated 3,4-dihydroxyphenylalanine (DOPA)-containing peptides coordinate with metal ions such as iron, chromium, and vanadium to form stable nanocondensates within dense-granular cells. These nanocondensates are secreted into the extracellular matrix and rapidly incorporated into
