Electromagnetic enhancement effects through localized surface plasmon resonance considerably amplify the intensity of incident light when molecules are positioned in the vicinity of miniscule nanogaps. The aggregation of plasmonic nanoparticles synthesized using bottom‐up methods has been extensively used to generate hot spots in solutions. These methods assist in obtaining non‐periodic plasmonic...
Nanodimpled Substrates
In article number 2105703, Sang‐Woo Joo, Lingxin Chen, Jaebum Choo, and co‐workers develop a nanod impled Au substrate with 80 nm‐sized AuNPs uniformly inserted into its cavities. Precise nanogaps are generated by regularly internalizing AuNPs in the cavities of nanodimples through DNA hybridization. This system can be applied to SERS‐PCR and drastically reduces the number of...
