Abstract: The invention relates to a composition comprising a polymer-based droplet, wherein the polymer-based droplet comprises one or more of melanin, a tyrosine substrate with a cleavable protecting group on the side chain, tyrosine, tyrosinase and any combination thereof. The composition further relates to a method of synthesizing melanin comprising the steps of: obtaining a polymer-based droplet containing a tyrosine substrate with a cleavable protecting group on the side chain (protected tyrosine) or a polymer-based droplet containing tyrosine (unprotected); wherein the tyrosine is oxidized by tyrosinase and polymerizes so as to obtain melanin.
