As the initial experiments towards integrating the near-field ablation and a fiber-optic biosensor, we report the near-field ablation on Arabidopsis thaliana leaf samples with a 2µm ablation spot. We also report time-dependent spectral plots of detecting biomolecules in the ground Arabidopsis leaf solution. The sensitivity of detecting biomolecules with amino functional groups was improved by using...
Chemical analysis of metabolites directly from cell samples at sub-cellular level in ambient conditions is essential to understand the biochemical pathways in these organisms. In order to achieve this goal we combine near-field ablation with mass spectrometry. As a first step towards the integration of near-field ablation with mass spectrometry, we will report preliminary results of the chemical analysis...
