Thesis: Immobilization of gold nanoparticles on N,N'-bis(2-pyridylmethyl) 2-hydroxyethylamine functionalized single-walled carbon nanotubes and study of catalytic activity = N,N'-bis(2-pyridylmethyl) 2-hydroxy-ethylamine


Current Research Project and Objectives:
Photosynthate-responsive polymeric nano-carriers for phloem-specific delivery in the treatment of HLB (Huanglongbing)

My roles in this project include the synthesis and analysis of sugar-responsive degradable polymeric nanocarriers and encapsulation of antibiotics for HLB. The nanocarriers are anticipated to be cure HLB-affected citrus trees.
