Effect of Nano particles on antibacterial activity of aloe Vera

Abstract EN

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.
