MicroRNAs (miRNAs) present an important target for medical diagnostics of various serious diseases. We report a novel method for rapid and sensitive miRNA detection and quantization using high-performance portable surface plasmon resonance (SPR) sensor combined with a DNA*RNA antibody-based assay. The new approach allows detecting miRNA at levels down to high attomoles in less than 30 minutes. The methodology is found to yield results which agree well with established methods for miRNA detection.
