While the nanometer scale mode volumes still prevent single letter identification of DNA sequence, we show an alternative method for identifying A, T, G, C DNA nucleotides in “k-mers” using sequences of these blocks as a unique and high-throughput alternative to single letter sequences (similar to binary and hexadecimal systems). Furthermore, additivity shown in single-molecule DNA mixtures and robust optical signatures can also be used in a raster-type step scan to identify single letter sequences. These results can pave the way for the development of a novel, high-throughput block optical sequencing (BOS) method."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-throughput block optical DNA sequence identification","description":"Disclosed herein is a multiplexed design with three-dimensional plasmonic nanofocusing and confinement of light, demonstration of reproducible and robust single-molecule optical fingerprints using two","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11473135","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
