Nanoparticles Before Nanotechnology

We are glad to present another NanoWiki compilation, following 'Balancing the promises' and 'Engines On'. This year we chose the subject of Nanoparticles Before Nanotechnology simply because we were suspicious that nanoparticles are too often, in scientific and non-scientific circles, perceived as invented, while we think they should be understood as discovered. Nanomaterials are claimed to be so new that people become scared. However, before nanotechnology, one can find nanoparticles in the works of both nature and Man, although they passed unnoticed by us until recently. The origin of nanoparticles in nature is basically i) biogenic, ii) geogenic (and also at the bio-inorganic interface), or iii) cosmogenic, while the nanoparticles produced by men come unintentionally from origins as burning wood and oil or unnoticed in crafted stuff such as cosmetics and colored glass and ceramics. nanowiki edicions ebook #3
