What is Nanotechnology?
Nanotechnology is attracting growing interest
worldwide. The word 'nano' comes from the Greek word 'dwarf' and it means that
the size of the particles are really, really small. It also refers to the
creation, investigation and application of structures, molecular materials,
internal interfaces or surfaces with at least one critical dimension or
manufacturing tolerances of (typically) less than 100 nanometers.
As you may already know; rainwater is repelled by lotus plants. Why? Because these plants have a natural cleaning mechanism and raindrops have almost no contact with the surface. Water droplets roll off the leaf and take dirt, insects, contaminants, water based adhesives, honey, oil and other substances with them.
