Kind: research · Impact: low

## In brief

- Gold nanoparticles enhanced the mass spectrometry signal from astrobiologically relevant molecules, including histidine and vitamin K1, in laser desorption ionization.
- Silver nanoparticles were found to be ineffective for the same purpose.
- The study by Nikita J. Boeren et al. was published in Planetary Science Journal (2026, vol. 7, article 217).

## Why it matters

Laser desorption mass spectrometry is a candidate technique for detecting organic molecules in space instruments, so a signal boost for key biomolecules could improve sensitivity of such measurements.
