Abstract

This paper introduces a portable Raman leaf-clip sensor for rapid, in vivo spectral analysis of plant metabolites, enabling early diagnosis of plant stresses like nutrient deficiency and drought. The sensor's effectiveness is demonstrated using Arabidopsis thaliana and vegetable crops, showing consistent results with benchtop Raman spectrometer measurements. This device offers a new tool for precision agriculture.
