Magnetic Nanocomposites and Their Incorporation into Higher Order Biosynthetic Functional Architectures

A magnetically active Fe₃O₄/poly­(ethylene oxide)-block-poly­(butadiene) (PEO-b-PBD) nanocomposite is formed by the encapsulation of magnetite nanoparticles with a short-chain amphiphilic block copolymer. This material is then incorporated into the self-assembly of higher order polymer architectures, along with an organic pigment, to yield biosynthetic, bifunctional optical and magnetically active Fe₃O₄/bacteriochlorophyll c/PEO-b-PBD polymeric chlorosomes.
