제목 Structure Specific Enzymatic Sensor for Universal Viral Nucleic Acid Detection via Surface-Enhanced Raman Spectroscopy (SERS)
초록 Viral nucleic acids are a valuable source for disease detection since it encodes every characteristic of a virus. This study presents a system in which flap endonuclease 1 (FEN1) is used to spot and quantify viral cDNA in a sensitive and swift manner. FEN1 is known to remove 5’ overhanging DNA flaps depending on specific double-flap structures. Synthetic DNA strands according to random cDNA fragments of viral mRNA target sequence forms a double-flap structure with two kinds of additive oligonucleotides, enabling recognition by FEN1: Raman dye labeled probe that is partially complementary and forms a 5’-flap, and another sequence providing 3’-1nt flap. FEN1 removes the Raman dye labeled 5’-flap from the double-flap substrate which is used to trace the presence of target viral gene sequence by SERS. This system detecting any gene with considerably high speed and sensitivity can lead to a step forward to preemptive prevention of widespread viral infectious diseases.
