In this work, synthesis of CdS nanoparticles with Aloe vera (L.) extract and its
activity on bacterial pathogens was investigated. CdS nanoparticles were synthesized
by using chemical methods. Physical properties like: X- ray diffraction (XRD),
Atomic force microscopy (AFM) and UV-VIS transmission spectroscopy were
employed to characterize the crystalline structure, size and transmission spectra of
nanoparticles. X-ray diffraction analysis confirms the formation of cubical and
hexagonal structures of CdS nanoparticle. The AFM show the formation of aggregate
of nanoparticle with particle size ranging 7 – 20 (nm). The antibacterial activity of
Aloe vera-conjugated CdS nanoparticles showed effective inhibitory activity against
the pathogens.
Keywords: Aloe Vera, Nan particles, Antibacterial Activity, Chemical Method.
