Abstract
Degradation of halocarbons using silver and gold nanoparticles has been utitlised for the synthesis of empty nanoshells of nanobubbles starting from coreshell particles. The studies conducted were mainly on zirconia and silica nanoshells. Removal of the metal core was followed by UV-visible spectroscopy. The properties of nanoshells were further modified by incorporating molecules namely ciprofloxacin and aniline inside shell. The new materials obtained were characterized using UV-visible spectroscopy, emission spectroscopy and transmission electron microscopy. Aniline@SiO2 was found to have pH sensing property with complete reversibility. When confined inside the silica shell, aniline shows an additional red shifted peak apart from the usual fluorescence peak. This additional peak is attributed to the emission from excimers of aniline.
