Some off the nanoparticles are useful for our body too. Fluorescent nanoparticle helps to image tumors and organ damage. Plastic nanospheres are used to encapsulate protines called cytokines that stimulate our immune system’s killer T-cells. These spheres can be used to fight against diseases and infection.

Nanoparticles can flow though our blood & can penetrate cells. Some of these particles can cause lung damage. Our brain can be affected by them too.

Nano -particles of silver is used to manufacture antibacterial bandages. Silver ions kills the harmfull cells.

Nokia is now working on nanotech superhydrophobic coating that will make its devices water resistant. Nokia is now trying to add a nanostructure on the surface of devices so that water just rolls over it and can not cause any damage.

Some clothing companies has introduced clothing items that are stain proof and that can even resist wrinkles! These clothing items are made with the help of nanotech fibers.

Self cleaning glass This glass has has two properties- hydrophilic and photocatalytic. With the presence of hydrophilic effect, the water that contact with the glass, spreads across the glass evenly. For the photocatalytic effect, the nanoparticles break down due to UV radiation and removes the dirt.

Another nanotechnology product called nanocrystals can be used to make the original metals more stronger by mixing with it.

Nanotechnologies are used for cleaning ocean water from toxic elements like (mercury, lead) etc by using a tube with nanotech coating process which acts like a sponge.

One area of nanotechnology application that holds the promise of providing great benefits for society in the future is in the realm of medicine. Nanotechnology is already being used as the basis for new, more effective drug delivery systems and is in early stage development as scaffolding in nerve regeneration research. Moreover, the National Cancer Institute has created the Alliance for Nanotechnology in Cancer in the hope that investments in this branch of nanomedicine could lead to breakthrou

A "nano-needle" with a tip about one-thousandth the size of a human hair pokes a living cell, causing it to quiver briefly. Once it is withdrawn from the cell, this ORNL nanosensor detects signs of early DNA damage that can lead to cancer.
