Application of Micro- and Nano-Spectroscopic Techniques for Systematic Studies of Surface Features of the Barley Leaf Cuticle.

ABSTRACT: In this study, micro- and nanospectroscopic techniques were used to examine the aerial epidermis of a barley crop leaf cuticle to determine if there is a correlation between aerial morphological features and their chemistry. We believe this understanding may inform the design of nanoparticles (NPs) with improved and controlled NP-plant interactions and potential applications as foliar nanofertilizers. We compared three different Raman excitation wavelengthsNIR, Vis, and UVand evaluated the possibilities of nanospectroscopic techniques like tip-enhanced Raman spectroscopy (TERS) and nano-FTIR spectroscopy. All measurements were performed on a fresh leaf surface. The impact of excitation wavelength and other measurement parameters (laser power, exposure time) to obtain an optimal signal-to
