摘      要：Here,we use two important biomaterials,protein and DNA,to construct self-assembled linear nanostructures through Watson-Crick base-paring of *** apply a simple magnetic separation method to purify traptavidin-DNA co njugates,and demonstrate synthesis of linear arrays of traptavidinDNA conjugates via the step-growth polymerization approach with pre-determined DNA *** the traptavidin-DNA array as a template,we assemble gold nanoparticles to form linear plasmonic nanostructures in a programmable *** traptavidin-DNA conjugates thus provide a convenient platform for one-dimensional assembly of biotinylated nanomaterials for many biomedical applications from drug delivery to bio-sensing.
