文摘

DDI can be used to easily manufacture multimodal plasmonic nanostructures. LSPR biosensing multiplexed platforms can be developed using multifunctional DNA encoded AuNP. DDI manufactured LSPR chips provide high detectability as demonstrated analyzing AAS. Dual identification diagnostic chips can be accomplished through DDI strategy.
