The invention concerns a method for analysing the intracellular chemical
state of living cells by nuclear magnetic resonance (NMR). Said method
comprises a step which consists in preparing the cell sample and a step
which consists in an NMR analysis of the sample, both steps being carried
out at very low temperature so as to freeze the biochemical state of the
living cells to obtain specific and accurate reproducible measurements of
the cellular functioning in given conditions. The invention also concerns
the device coupled to the NMR spectrometer for implementing the method of
analysis.
