The synthesized materials were characterized by various microscopic and spectroscopic techniques (e.g., SEM, TEM, XRD, Raman, XPS, EDX, and FTIR spec troscopy), showing that the formed carbon spheres (CSs) exhibited uniform morphology and surface structure with abundant oxygen functional groups. The dimension of the formed CSs could be easily tuned by altering the AA concentration, reaction time, and temperature. A mechanism for the formation of the CSs was proposed, and their antibacterial activities were also investigated against two bacterial strains, showing the inhibition rate of 94 percent for E. coli and 100 percent for S. aureus. This biocidal activity was achieved with the pure CSs produced from the inexpensive AA (Vitamin C) via a rapid green process without any further surface modification or doping, thus promising for myriad surface coating, medical and environmental applications.14aSURFACE SCIENCE14aCARBON MICRO-SPHERE14aASCORBIC ACID14aMICROWAVE-ASSISTED SYNTHESIS14aANTIMICROBIAL ASSAY12aAbdulwali, N.12avan der Zalm, J.12aThiruppathi, A.
