Abstract
Carbon nanoparticles (CNPs) are isolated from chimney soot and characterised by various tools such as X-ray diffraction, scanning electron microscopy, transmission electron microscopy and ultraviolet-visible spectroscopy. The X-ray diffraction studies confirm the presence of C60 nanoparticles in the isolated sample. The thermal properties of the prepared CNPs are recorded using thermogravimetric analysis and differential thermal analysis. The analysis of the antibacterial activity of the synthesised CNPs against selected Gram-positive and Gram-negative bacterial strains is also investigated. The systematic study confirms that CNPs collected from chimney soot exhibit good antibacterial potency against Staphylococcus aureus, Streptococcus pyogenes, Klebsiella pneumoniae, and Proteus mirabilis.
