(182e) Enhancing Light Absorption Properties of Hybrid Magnetic Nanoparticles Using Metal Chelation and Electroless Deposition of Metal Ions.

This work describes the different characteristics of light absorption of hybrid magnetic nanoparticles when using different chelated metal ions or electroless deposited. Fe₃O₄@Agarose core-shell nanoparticles were modified to incorporate polydopamine (PDA) as a second shell. Fe₃O₄@Agarose-PDA nanoparticles make black solutions capable of absorbing a considerable amount of light. However, to make the nanoparticles more conductive, a metal can be deposited onto the surface of the particles. In this work, metal chelation and electroless deposition were proposed as a way to increase conductivity and change the absorption characteristics of the particles.
