Nano is a Greek word which means " dwart" . One nano meter is 1/10 9th of meter. Nano materials have size between 1 nano meter and 100 nanometer . He Know a molecule is the smallest particle of substancewhich shows the same physical and chemical properties of the parent substance. Carbon , Hydrogen and Oxygen atoms should combine in a certain proportion for the formation of the Sugar . If the proportion or order is changes , sugar is not formed. Thus properties of a substance depend on atom and their arrangement in a material. The diameter of a Hydrogen atom is 0.1 nanometer ie when ten Hydrogen atoms are placedin a staright line,it is one nanometer .
Nano technology cannot stated as a branch of science. it is the science of science and creating revolutionary change . It includes material Science , Physics Engineering , Chemistry , Biology , Computer Science , Electronics , information technology etc . This technology is able to create unbelievable revolutionary changes in our day today life
Nano technology finds highly effective application in Medical science. for instance , medicine with magnetic propertie , if it is injected ito the human body , then by applying suitable magnetic field outside the body bring these medicines into a particular region /spot as we need.
