초록

Nanoparticles have been pivotal in combating viral and bacterial infection diseases due to their high surface area to volume ratio, which allows them to effectively eliminate viruses even at low concentrations. This property is further enhanced as the size of the nanoparticles decreases, attributed to the higher dispersity of the nanoparticles. However, there has been limited research on improving the dispersity and then minimizing the sizes of binary and ternary component nanoparticles, particularly synthesized by incorporating graphene with metal-based nanoparticles including copper (Cu) and silver (Ag), to enhance antiviral and antibacterial properties. To address this issue, we investigate the size control of binary and ternary component nanoparticles, including Cu-graphene, Aggraphene and Cu-Ag-graphene, by altering pH conditions during synthesis. The sizes of resultant nanoparticles are analyzed using transmission electron microscopy (TEM). Our findings indicate that Cu-Ag-graphene nanoparticles, synthesized under reductive conditions (pH 12), exhibit the highest dispersity and the smallest sizes, suggesting they could be highly efficient in antiviral and antibacterial activity.
