A single-step strategy has been developed for synthesizing a micrometer-sized structure by using the raspberry-like hybrid as a building block comprising a repeated sequence of a three-dimensional gold nanoparticle (AuNP)-aniline oligomer-AuNP arrangement. The hybrid holds a high density of highly dispersible AuNPs without any contact with each other, and therefore the microstructure has many nanometer-sized gaps between the adjacent AuNPs for both electrical and optical sensing. We have discussed how the formation mechanism of the microstructure is based on using the hybrid.
