Clustering Nuclear Magnetic Resonance: Machine learning assistive rapid two‐dimensional relaxometry mapping

Abstract: Low‐field nuclear magnetic resonance (NMR) relaxometry is an attractive approach from point‐of‐care testing medical diagnosis to in situ oil‐gas exploration. One of the problems, however, is the inherently long relaxation time of the (liquid) samples, (and hence low signal‐to‐noise ratio) which causes unnecessarily long repetition time. In this work, a new class of methodology is presented for rapid and accurate object classification using NMR relaxometry with the aid of machine learning. It is demonstrated th… Show more

“…These include magnetic resonance relaxometry, 32,33 magnetic deposition microscopy, 34 novel photoacoustics, 25 biosensors and lab-on-a-chip techniques, 35 and multiomics-based sensors. 36 Apart from these, there are new techniques that function with the aid of machine learning; these include rapid and object classification using lowfield nuclear magnetic resonance (NMR) relaxometry, 37 hemozoin-based techniques, 38 spectroscopy-based techniques such as impedance spectroscopy, terahertz spectroscopy, 39 and whole-genome sequencing. 40 While these novel technologies are being developed, however, RDTs and UMTs will remain a mainstay in malaria diagnosis for a long time, especially in developing countries.…”

“…The data on antigenic epitopes presented in this study will inform on the purchase and supply of effective RDT in Tanzania. There is an urgent need to deploy a novel and unconventional point-of-care test that exploits magnetic resonance in malaria diagnosis [ 46 , 47 ].…”

“…Metabolite differences were revealed, with GABA found to be produced in the plants responses to the ozone exposure (i.e., changes in oxidative stress) [ 138 ]. These 4IR technological and software developments in NMR will, therefore, enable rapid analysis for large datasets and potentially increase the widespread use of NMR-based plant metabolomics [ 139 ]. In this review, we mainly focus on LC-MS and LC-MS/MS platforms and their data processing and analysis workflows.…”
