Abstract
Circulating serum microRNAs (miRNAs) are promising biomarkers for disease diagnosis. The quantification of the serum miRNA copy number is a challenge due to the presence of low levels in the serum. Here, we report on a direct measurement of the miRNA copy number from human serum using a locked nucleic acid (LNA) modified beacon probe with a single step using fluorescence spectroscopy and microscopy. We had used a minimum volume of 0.1 μL healthy human serum and retinoblastoma serum to show the biological variation of the miRNA copy number.
