Abstract

The current work shows how catalyst‐free carbon nanospheres (CNS) can be produced utilizing straightforward one‐step pyrolysis methods employing biowaste Caesalpinia sappan pods as a carbon precursor. The manufactured CNS with a particle size range of 40–50 nm that is obtained show a porous nature and contain more than 87% carbon. The synthesized CNS are used as potential antibacterial agents against E. coli and S. aureus by microscopic analysis. By observing the distorted cell envelopes of both E. coli and S. aureus compared with those of untreated cells, it is well understood that CNS, by binding to the outer envelope of cells, renders some changes in the peptidoglycan layer of both Gram‐positive and Gram‐negative microbes, which in turn restricts their further growth. This study confirms the first report of use of CNS as an effective antibacterial agent.
