报告简介：In this talk, I will present our recent work on linker-mediated designed assembly, including the linker-mediated addressable assembly of DNA-coated colloids [Sci. Adv., eaaz6921 (2020)], and the superselectivity in the linker-mediated adsorption of DNA coated colloids [arXiv:2310.15834 (2023)]. 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.
