Aim/Objective: The author writes the manuscript by reviewing the literatures related to the
biomedical application of metallic nanoparticles. The term metal nanoparticles are used to
describe the nanosized metals with the dimension within the size range of 1-100 nm.
Methods: The preparation of metallic nanoparticles and their application is an influential
area for research. Among various physical and chemical methods (viz. chemical reduction,
thermal decomposition, etc.) for synthesizing silver nanoparticles, biological methods have
been suggested as possible eco-friendly alternatives. The synthesis of metallic nanoparticles
is having many problems inclusive of solvent toxicity, the formation of hazardous byproducts and consumption of energy. So it is important to design eco-friendly benign
procedures for the synthesis of metallic nanoparticles.
Results: From the literature survey, we concluded that metallic nanoparticles have
applications in the treatment of different diseases. Metallic nanoparticles are having a great
advantage in the detection of cancer, diagnosis, and therapy. And it can also have properties
such as antifungal, antibacterial, anti-inflammatory, antiviral and anti-angiogenic.
Conclusion: In this review, recent upcoming advancement of biomedical application of
nanotechnology and their future challenges has been discussed.
