Abstract
A metal nanoparticles-doped porous carbon bead having an average size of about 0.4 millimeter (mm) to about 0.6 mm is provided. The metal nanoparticles-doped porous carbon bead is doped with silver, copper, or combinations thereof.
Claims6
A metal nanopartieles-doped porous carbon head having an average size of about 0.4 mm to about 0.6 mm, wherein a porous carbon bead is doped with silver and copper nanoparticles and a loading of silver is about 1 milligram (mg) to about 6 mg per gram (g) of the porous carbon bead and a loading of copper is about 5 mg to about 25 mg per gram (g) of the porous carbon bead, wherein the metal nanoparticles-doped porous carbon bead is an antibacterial agent and provides 100% inhibition of bacteria in a sample for a time period of about 100 hours to about 130 hours, and wherein the bacteria are gram-positive bacteria, gram-negative bacteria, or combinations thereof.
An antibacterial agent for inhibiting bacteria, the antibacterial agent comprising one or more metal nanopartieles-doped porous carbon beads, wherein the one or more porous carbon beads are doped with silver and copper nanoparticles and a loading of silver is about 1 milligram (mg) to about 6 mg per gram (g) of the porous carbon beads and a loading of copper is about 5 mg to about 25 mg per gram (g) of the porous carbon beads, wherein the silver and copper nanoparticles are substantially uniformly dispersed within pores of the porous carbon bead and provides 100% inhibition of bacteria in a sample for a time period of about 100 hours to about 130 hours, and wherein the bacteria are gram-positive bacteria, gram-negative bacteria, or combinations thereof.
