Pioneering nanobiodevice can isolate cancer biomarkers quickly with high resolution Quartz-made Nanopillars of 250-nm diameter were arrayed inside nanoslit region of 100-nm high and applied for ultrafast microRNA extraction from nucleic acids mixture. Like DNA, ribonucleic acid (RNA) is a type of polymeric biomolecule essential for life, playing important roles in gene processing. Short lengths...
