Single Locked Nucleic Acid-enhanced nanopore genetic discrimination of pathogenic serotypes and cancer driver
Abstract:
Rapid and accurate detection of single-nucleotide polymorphism (SNP) in pathogenic mutants is crucial for broad fields from food safety monitoring to disease diagnostics and prognosis. Here, we developed a nanopore single-molecule sensor, coupled with the locked nucleic acid (LNA) technique, to accurately discriminate SNPs for detection of Shiga toxin producing Escherichia coli (STEC) O157:H7 pathogen serotype, and cancer-derived driver mutations EGFR L858R and KRAS G12D. This sensitive method, with a simplified, low cost, easy-to-operate LNA design, can be applied in food science and medical detection that need rapid and accurate determination of genetic variations.

Nucleic acids
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...
