The problem
MicroRNAs (miRNAs) are notoriously difficult to quantify accurately due to their high degree of homology and small size. Their low abundance in circulation further aggravates this difficulty. Interestingly, increasing evidence shows that low abundant miRNA targets in biofluids carry diagnostic value for early detection of diseases.
Hence, there is mounting demand for improved detection and quantification methods, especially since their promise as novel diagnostic and prognostic biomarkers for multiple human diseases is just being realized.
The small size of microRNAs makes detection extremely difficult. Less than 100 miRNAs are robustly detected in biofluids.
