Label-Free MicroRNA Optical Biosensors [PDF]

open access: yesNanomaterials, 2019
MicroRNAs (miRNAs) play crucial roles in regulating gene expression. Many studies show that miRNAs have been linked to almost all kinds of disease. In addition, miRNAs are well preserved in a variety of specimens, thereby making them ideal biomarkers for
