Query: NMR microscopy for in vivo metabolomics, digitally twinned by
  computational systems biology, needs a sensitivity boost   The metabolism of an organism is regulated at the cellular level, yet is
strongly influenced by its environment. The precise metabolomic study of living
organisms is currently hampered by measurement sensitivity: most metabolomic
measurement techniques involve some compromise, in that averaging is performed
over a volume significantly larger than a single cell, or require invasion of
the organism, or arrest the state of the organism. NMR is an inherently
non-invasive chemometric and imaging method, and hence in principle suitable
for metabolomic measurements. The digital twin of metabolomics is computational
systems biology, so that NMR microscopy is potentially a viable approach with
which to join the theoretical and experimental exploration of the metabolomic
and behavioural response of organisms. This prospect paper considers the
challenge of performing in vivo NMR-based metabolomics on the small organism C.
elegans, points the way towards possible solutions created using MEMS
techniques, and highlights currently insurmountable challenges.
