Abstract

A convenient and cost-effective chemical approach was developed to fabricate Au aggregates with uniform 1 nm nanogaps through the assembly of cucurbit[n]urils with Au colloids. Cucurbit[n]urils located in the nanogap region can be used as a useful SERS hot-spot nanocontainer to realize the SERS enhancement of an “inert” molecule up to 109.
