**6. Conclusion**

The use of AgNPs as antibacterial agents must, therefore, be extended. Moreover, extensive research and development towards applying for multifunctional AgNPs and study on human health and the environment impacts are much needed. Then, the development of technology to prevent systemic side effects is also required. Numerous studies showed that AgNPs could slow down the viability of the antiviral activity's exact mechanism remains elusive and demand further testing. In future, the environmentally sustainable and advance approach of AgNPs synthesis could provide a viable alternative method to traditional physical and chemical methods.
