| Abstract: | Metallic nanoparticles are traditionally synthesized by wet chemical
techniques, where the chemicals used are often toxic and flammable. In the
present study, the spore crystal mixture of Bacillus
thuringiensis was used for the synthesis of silver nanoparticles.
Nanoparticles were characterized using UV-Vis absorption spectroscopy, XRD and
TEM. X-ray diffraction and TEM analysis showed the average particle size of 15
nm and mixed (cubic and hexagonal) structure.
This is for the first time that any bacterial spore crystal mixture was used for the synthesis of
nanoparticles. Further, these biologically synthesized nanoparticles were found
to be highly toxic against different multi drug resistant human pathogenic
bacteria. |
