In the last few decades, nanomaterials (materials with a size between 1 and 100 nm) have attracted much attention due to their unique physical-chemical properties compared to bulk materials.

Silver nanoparticles have been at the forefront of recent nanotechnology research, with applications ranging between photonics and medicine. Their tunable photophysical characteristics, the addressability through optical and spectroscopic methods, and the rapid advancements in nanoparticle synthesis & fabrication have brought these particles to the forefront.

Synthesis of silver nanoparticles

Silver nanoparticles are generally synthesized by two approaches, (i) the "top to bottom" approach and (ii) the "bottom to top" approach.

The "top to bottom" approach refers to the formation of metal nanoparticles from bulk materials, while in the "bottom to top" approach, nanoparticles are synthesized using chemical and biological methods by self-assembly of atoms to new nuclei, which grow into nano-size particles.

Applications of silver nanoparticles

Due to their unique properties, such as size and shape, which depend on optical, electrical and magnetic properties, silver nanoparticles have attracted great interest. They can be subsumed into antimicrobial applications, biosensor materials, composite fibers, cryogenic superconducting materials, cosmetic products and electronic components. Nanoparticles have numerous applications in different fields, such as medical imaging, nano-composites, filters, drug delivery and tumor hyperthermia.

Antimicrobial Activity: AgNPs have been used tremendously as anti-bacterial agents in the health industry, food storage, textile coatings, and numerous environmental applications, as an antibacterial agent, from fumigating medical devices and home appliances to water treatment cotton fibre.

Cancer Control: Since AgNPs can disrupt the mitochondrial respiratory chain, they could be expanded to instigate reactive oxygen species (ROS) production, ATP synthesis, and finally, DNA damage. Otherwise, they can perform well in cancer therapeutics.

Antidiabetic Activity: AgNPs scavenged free radicals, reducing the levels of enzymes that hydrolyze complex carbohydrates (a-glucosidase and a-amylase), and as a result of this, there is an increase in the consumption rate of glucose.
