In this talk, I will present our recent work on linker-mediated designed assembly, including the linker-mediated addressable assembly of DNA-coated colloids [1], and the superselectivity in the linker-mediated adsorption of DNA coated colloids [2]. I will discuss how we can use linkers as a smart agent to realise the designed precise fabrication on the nano scale as well as to design new sensors for detecting biomarkers, e.g., COVID.
