Nanomaterials is a field which takes a materials science-based approach to nanotechnology.

Nanomaterials studies materials that have very different properties on the nanoscale.

Nanoscale means smaller than one tenth of a micrometer in at least one dimension of an object.

buckyball clusters Nanotubes Megatubes Polymers Nano “onions” linked "ball-and-chain" dimers fullerene rings

Fullerenes are molecules made completely out of carbon, regardless of its molecular structure. They can come in spheres, cylinders, ellipsoids or tubes.

Cylindrical fullerenes are also known as carbon nanotubes or buckytubes.

Fullerene=Buckyball The first fullerene (buckminsterfullerene C60) was made by Robert Curl, Harold Kroto and Richard Smalley in 1985.

The name was a homage to Richard Buckminster Fuller as fullerenes resemble his geodesic domes.

Silver nanoparticles are silver particles that are between 1 nm and 100 nm in size.

Some silver nanoparticles are composed mainly of silver oxide.

Ways to produce silver nanoparticles:1. Physical vapour deposition2. Ion implantation3. Wet chemistryMedical Uses:1.bone cement2.surgical instruments 3.surgical masks 4.wound dressings 5.treatment of HIV-1

They are highly reactive because of their large surface area.

Iron nanoparticles are widely used in:1. medical and laboratory applications 2. remediation of industrial sites

contaminated with chlorinated organic compounds

Iron nanoparticles can be used to treat several forms of ground contamination, including grounds contaminated by polychlorinated biphenyls (PCBs), chlorinated organic solvents, and organochlorine pesticides.

They tend to agglomerate on soil surfaces and can be easily transported through ground water.

Platinum nanoparticles are usually in the form of a suspension or colloid of sub-micrometre-sized particles of platinum in a fluid, usually water.

A colloid is defined to be particles which remain suspended without forming an ionic or dissolved solution.

Platinum nanoparticles range between 2-3nm.

They have antioxidant properties and are substantially researched.

Platinum nanoparticles may have applications in the following areas:

1. Nanotechnology2. Medicine3. Synthesis of novel materials with unique

properties

Colloidal gold/Gold nanoparticles is a suspension (or colloid) of sub-micrometre-sized particles of gold in a fluid — usually water.

Since ancient times, colloidal gold is synthesized for staining glass.

A relatively simpler method of producing gold nanoparticles is to reduce chloroauric acid.

Now, colloidal gold is a subject of substantial research as it may have applications in many fields:

1. Electron microscopy2. Electronics3. Nanotechnology4. Materials science Colloidal gold is used as a therapy for

rheumatoid arthritis in rats. The implantation of gold beads near arthritic

hip joints in dogs has been found to relieve pain.
