A novel approach for synthesizing polydopamine (PDA)-based nanocomposites with a multifunction is demonstrated. Due to the special interactions between metal precursors and the PDA, individual nanoparticles (NPs) were selectively synthesized or positioned within the PDA from core to shell. By varying the reaction cycles, it was able to control the loading amount of metal NPs up to almost 100 % of the PDA particles. Thanks to highly loaded metal NPs within the PDA particles, we expect that the PDA nanocomposites described here can be used for an efficient catalyst for reduction of organics as well as a drug carrier for controlled release. |
