ANTIMICROBIAL ACTIVITY OF NOVEL POROUS ZNGD2O4 NANOPARTICLES EXHIBIT NANOPARTICLE-BACTERIA INTERFACE

The porous and novel ZnGd2O4 nanoparticles with oval morphology were
synthesized by simple combustion method. The presence of wurtzite ZnO nanophase
with Gd2O3 spinal nanoparticles inside ZnGd2O4 were confirmed by the use of
XRD pattern and supportive FTIR spectrum. XRD data proved phase purity of the
nanomaterial. These porous nanoparticles had shown good surface activity and
stability on the basis of thermal analysis. The elemental composition and porous
nature of these nanoparticles were confirmed on the basis of SEM-EDAX analysis.
The 55 nm. size of these nanoparticles was matched with TEM–SAED pattern.
These porous metal oxide nanoparticles had exhibited good surface activity and
biocompatibility on the basis of antimicrobial screening on gram positive and gram
negative bacteria. Hence these nanoparticles find applications in future biomedical
and sensing fields.
