Cancer Diagnostics: Quantitative and Specific Detection of Exosomal miRNAs for Accurate Diagnosis of Breast Cancer Using a Surface‐Enhanced Raman Scattering Sensor Based on Plasmonic Head‐Flocked Gold Nanopillars (Small 17/2019)

In article number 1804968, Kyong Hwa Park, Sang Jun Sim, and co-workers develop a surface-enhanced Raman scattering (SERS)-based ultrasensitive exosomal miRNA detection platform with single-nucleotide specificity, obtained by enhanced SERS signals from uniform plasmonic head-flocked gold nanopillar SERS substrate that generates self-assembled hot spots and enables hybridization between short oligonucleotides (i.e., miRNAs and locked nucleic acid probes).
