Metal Nano Powder

Metallic nanoparticles have attracted scientists over a century and now heavily utilized in various fields.They are a  center of interest because of their huge potential in nanotechnology. These materials can be synthesized and modified with various functional groups, which allows them to be conjugated with ligands, antibodies, drugs and thus can be used in a wide range of applications in Catalysis, Sensing, Imagingetc.

Metal nanoparticles possess large surface energy; hence have the ability to adsorb small molecules. The recognition and capture of molecules at solid surfaces has numerous environmental and Bioanalytical applications. Metal nanoparticles are used as probe in detection and imaging of biomolecules due to ease of functionalization, greater sensitivity, size dependent optical properties and Photostability.

Nanoscaled materials are usually classified as materials having structured components with at least one dimension less than 100 nm. Smaller nanoparticles containing 104 or less atoms are referred to as nanoclusters. These clusters are of interest because they can explain the transition from atomic properties to bulk material properties. There are different types of nanoclusters are: vander walls nanoclusters, ionic nanoclusters, metalnanoclusters.

Nanoparticles (NPs), and noble metal NPs, are versatile agents with a variety of applications. The unique characteristics of noble metal NPs, such as high surface-to-volume ratio, broad optical properties, ease of synthesis, and facile surface chemistry and functionalization hold pledge in various fields.. Noble metal NPs (e.g., gold, silver, or a combination of both) present highly tunable optical properties, which can be easily tuned to desirable wavelengths according to their shape (e.g., nanoparticles, nanoshells, nanorods, etc.), size (e.g., 1 to 100 nm), and composition (e.g., core/shell or alloy noble metals), enabling their imaging and photothermal applications.

Metal  NPs can also be easily functionalized with various moieties, such as antibodies, peptides, and/or DNA/RNA to specifically target different cells and with biocompatible polymers (e.g., polyethylene glycol and PEG).
