Abstract

Thepreparation of smart aptamer DNA-assembled gold nanoparticles that are responsive to multiple chemical stimuli with controllable cooperativity was investigated. Three kinds of nanoparticles were mixed in a particle 1/particle 2A/particle 2B ratio of 2:1:1 and the mixed particles were centrifuged. Smart materials responsive to adenosine, cocaine, and K+ were demonstrated by incorporating aptamers to nanomaterials. Such materials can be applied for calorimetric sensing applications were multiple target molecules are present. Smart materials suitable for as a diverse range of applications can be obtained by replacing the gold nanoparticles with other nanomaterials such as quantum dots, nanotubes, or polymers.
