Peixuan Guo, Jeong-Woo Choi, and their team have developed monofunctionalized gold nanoparticles (AuNPs) featuring a single RNA three-way junction (3WJ) motif for ultra-sensitive miRNA biosensing. Utilizing electrochemical surface-enhanced Raman spectroscopy (EC-SERS), the presence of miRNA-155 triggers the displacement of the 3WJ structure, leading to a significant increase in both electrochemical and SERS signals. This innovative approach offers a highly sensitive method for detecting miRNA-155.-Journal cover design by scapiens
