Abstract

The main objective of this study was to investigate the uptake and translocation of positively charged zein nanoparticles (ZNPs) in hydroponically grown sugar cane plants. Fluorescent ZNPs (spherical and measuring an average diameter 135 ± 3 nm) were synthesized by emulsion-diffusion method from FITC-tagged zein. Fluorescent measurement following digestion of plant tissue indicated that sugar cane roots had a significant adhesion of ZNPs, 342.5 ± 24.2 μg NPs/mg of dry matter, while sugar cane leaves contained a very limited amount, 12.9 ± 1.2 μg NPs/mg dry matter for high dose(1.75 mg/ml) after 12 h. Confocal microscopy studies confirmed presence of fluorescent ZNPs in the epidermis and endodermis of the root system. Given their ability to adhere to roots for extended periods of time, ZNPs are proposed as effective delivery systems for agrochemicals to sugar cane plants, but more studies are needed to identify effect of nanoparticle exposure to health of the plant.
