Immobilization of Au nanoparticles on Au electrode for hydrazine detection: Using thiolated single-stranded DNA as a linker

In this article, we report a method for effective immobilization of Au nanoparticles (AuNPs) on thiolated single-stranded DNA (thiol-ssDNA) modified Au electrode (AuE) surface via coordination interactions between the nitrogen atoms of DNA bases and AuNPs. It suggests that the resultant AuNP-immobil...
