Single‐monolayer‐protected gold nanoparticles can be captured in the α‐hemolysin nanopore (see image). Single‐nanopore ion conductance studies of the nanoparticle/nanopore complex are described. The effect of the nanoparticle size, charge, and surface coating on ssDNA threading speed through the nanopore/nanoparticle complex is discussed.
