That feeling when you spent three weeks on a NanoSIMS mosaic just to falsify your initial hypothesis… At least 15N-ammonium uptake in the Hydra-Chlorella symbiosis looks pretty.

We, i.e. mainly @quantaofgeorge.bsky.social, for 1st time directly compared Raman microspectroscopy and NanoSIMS for single cell isotope probing. Conclusion: results from the 2 approaches compare well with each other allowing cross-technique comparisons. Choice of ion for SIMS matters. #microsky 🦠🧪
