Abstract: Provided herein are methods, compositions and associated formulations for hair treatment utilizing artificial melanin precursors and one or more amine compounds. In aspects, the one or more amine compounds facilitate alkaline conditions during the hair treatment, while being more tolerable to the hair, subject, and/or administrator compared to other conventional alkaline agents.

Abstract: Aspects of the invention include a method of capturing target compound(s) using a capture device, the method comprising: exposing the device to an environment comprising the target compound(s); wherein the device comprises: a porous artificial melanin material comprising: one or more melanin oligomers and/or polymers; wherein the melanin oligomers and/or polymers comprise a plurality of covalently-bonded melanin base units; wherein the melanin oligomers and/or polymers are arranged to form an internal structure having a plurality of pores; wherein the porous artificial melanin material is characterized by a pore volume per mass of material greater than or equal to 0.1 cm3/g and wherein at least a portion of said pores have at least one size dimension greater than or equal to 0.5 nm; and capturing the target compound(s) via an interaction between the porous artificial melanin material and the target compound(s).

Abstract: In an aspect, a plurality of artificial melanin nanoparticles are provided, wherein: each melanin nanoparticle of the plurality of artificial melanin nanoparticles comprises a plurality of melanin oligomers; each melanin oligomer comprises a plurality of covalently-bonded melanin base units; and each melanin base unit comprises substituted or unsubstituted naphthalene. In an aspect, porous artificial melanin materials and methods of synthesizing porous artificial melanin materials are provided.
