Sizing up the science, politics and business of nanotechnology

Nano-this and nano-that. Nanotechnology moves into the public consciousness. This 'nanotrend' has assumed 'mega' proportions: Patent offices around the world are swamped with nanotechnology-related applications; investment advisors compile nanotechnology stock indices and predict a coming boom in nanotechnology stocks with estimates floating around of a trillion-dollar industry within 10 years; pundits promise a new world with radically different medical procedures, manufacturing technologies and solutions to environmental problems; nano conferences and trade shows are thriving all over the world; scientific journals are awash in articles dealing with nanoscience discoveries and nanotechnology breakthroughs. Nanotechnology has been plagued by a lot of hype, but cynicism and criticism have not been far behind. The media can run amok when news about potential health problems with nanoproducts surface (as recently happened with a product recall for a bathroom cleaner in Germany). These discussions around nanotechnology epitomize the contemporary processes of making the future present. An interesting approach to dealing with the lack of consensus in the views on nanotechnology identifies eight main nodes of nanotechnology discourse and describes these "islands" of discussion, examines their interactions and degrees of isolation from each other.

From lotus leaves to self-cleaning windows

Superhydrophobic materials have surfaces that are extremely difficult to wet with water and therefore are of considerable interest for various industrial applications. Researchers have unlocked the mechanism that makes some leaves either superhydrophobic or hydrophilic, opening the way to creating self cleaning surfaces and interfaces that will not stick. Potential industrial applications are self cleaning windows and windshields, hard disks and magnetic tapes (for data storage) and MEMS and NEMS devices with no stiction issues.
