In today's world of biomedical tools and therapies, researchers are thinking big by thinking small with the arrival of pocket-sized ectrocardiographs for monitoring the heart and diagnostic cameras the size of a vitamin pill that travel the length of the digestive tract. These days, scientists are downsizing to the "nano" scale. Nanotechnology deals with the creation and use of materials or devices at the level of molecules and
atoms that are 1/1000th the width of a human hair—too small to be seen with a conventional laboratory microscope. Nanomedicine is an area of biomedical
research that seeks to use tools from the field of nanotechnology to improve health. Scientists say that the physical, chemical, and biological properties of materials
at the nanoscale differ in fundamental and valuable ways from the properties of larger-sized matter. Nanotechnology is changing the way materials and devices will be made in the future. With the ability to build products and devices atom-by-atom and moleculeby-
molecule, according to the National Nanotechnology Initiative (NNI)--a federal research and development program--scientists will create new classes of structural
materials that are expected to bring about lighter, stronger, smarter, cheaper, cleaner, and more precise products. And we know cancer also occurs at the cellular
level, hence nanotechnology can conveniently used for the treatment of cancer.
According to the NNI, more powerful nanotechnology developments expected in the next 10 years likely will include solutions to repair and rearrange
living cells.
