- ... Arrays of 20 nm silver nanoparticles (AgNPs) with tunable interparticle gaps have been grown on mesoporous silica (MPS) nanospheres to form AgNPs@MPS nanohybrids for surface-enhanced Raman scattering (SERS). Adenine was employed as the probing molecule to study the hot-spot SERS effect as a function of interparticle gap. The SERS signal intensity increased by 8–10-fold when the gaps were reduced t ...
