Noor Aniza Harun interests in material chemistry focusing on nanomaterials research areas particularly in polymer nanoparticles, quantum dots, metallic nanoparticles, nanoalloys and nanocomposites. Her present research is focused on the development of hydrophilic polymer nanoparticles and inorganic-hydrophilic polymer composite nanoparticles composed of encapsulation quantum dots (QDs) within polymer nanoparticles with potential application as fluorescent marker in medical and material sciences. She also involves in the research for the development of metallic nanoparticles that compliance with green technology approach utilizing polychaetes extract as biogenic reducing agents for various applications ranging from medical & pharmaceuticals, textile, aquaculture, coating and etc. All work relies strongly on the synthesis and characterizations using advanced instruments for instance dynamic light scattering (DLS), transmission electron microscopy (TEM), scanning electron microscopy (SEM), fluorescence microscopy and spectroscopy, UV-Visible spectroscopy, atomic force microscopy (AFM), and confocal Raman microspectroscopy.
