What is nanotechnology in civil engineering?

Nanotechnology is one of the most active research areas that encompass a number of disciplines, including civil engineering and construction materials. Nanotechnology is the re- engineering of materials and devices by controlling the matter at the atomic level (Roco et al., 1999).

What structures can be made from nanotechnology?

Interface and colloid science has given rise to many materials which may be useful in nanotechnology, such as carbon nanotubes and other fullerenes, and various nanoparticles and nanorods. Nanomaterials with fast ion transport are related also to nanoionics and nanoelectronics.

What is the role of nanotechnology?

Nanotechnology is expected to have a revolutionary impact on medicine. Nanoparticles can play a major role in medicine and especially in diagnosis and therapy of cancer, cardiovascular diseases and infectious diseases. Nanotechnology is on its way to make a big impact in Pharmaceutical and Medical diagnostics sciences.

Why is nanotechnology bad?

Nanoparticles are likely to be dangerous for three main reasons: Nanoparticles may damage the lungs. This is both because of their size (as they can get deep into the lungs) and also because they carry other chemicals including metals and hydrocarbons in with them.
