Synthesis of amphiphilic polysuccinimide star copolymers for responsive delivery in plants

While polymeric nanocarriers are widely used in medicine for controlled release and site-specific delivery, few reports have applied such delivery methods within agriculture, despite the urgent need for specific delivery of pesticides and nutrients. We report the synthesis of stimuli-responsive and biodegradable polymeric nanocarriers designed for delivery to the phloem of plants and describe methods employed to evaluate their toxicity in plant cells.
