Patent number: 11473135Abstract: 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 complementary vibrational spectroscopy techniques (infrared and Raman spectroscopy), identification of respective vibrational modes which uniquely fingerprint the biomolecular species, and facile differentiation of respective fingerprints in DNA mixtures, as well as epigenetic modifications. 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.Type: GrantFiled: December 6, 2018Date of Patent: October 18, 2022Assignee: THE REGENTS OF THE UNIVERSITY OF COLORADO, A BODY CORPORATEInventors: Prashant Nagpal, Manjunatha Sagar Dodderi
