Projects emerged to produce nanotechnology roadmaps[19][20] which center on atomically precise manipulation of matter and discuss existing and projected capabilities, goals, and applications. In its original sense, nanotechnology refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high-performance products. On the other hand, nanotechnology raises many of the same issues as any new technology, including concerns about the toxicity and environmental impact of nanomaterials,[9] and their potential effects on global economics, as well as speculation about various doomsday scenarios. Carbon nanotubes are stronger than steel and more flexible than rubber. Alternate-sized gold and silver particles created colors in the stained glass windows of medieval churches hundreds of years ago. [24] In the "top-down" approach, nano-objects are constructed from larger entities without atomic-level control.[25]. The main reason is the cytotoxicity and safety profile of NPs and their unknown impact on stem cell differentiation [73, 118]. Researchers have discovered that bacteriostatic silver nanoparticles used in socks to reduce foot odor are being released in the wash.[69] These particles are then flushed into the waste water stream and may destroy bacteria which are critical components of natural ecosystems, farms, and waste treatment processes. The microscope's developers Gerd Binnig and Heinrich Rohrer at IBM Zurich Research Laboratory received a Nobel Prize in Physics in 1986. I suppose I should just dismiss articles like this and not even bring them to peoples attention. Here are a few illustrative examples: Nanoscience and nanotechnology involve the ability to see and to control individual atoms and molecules. Nanotechnology is the understanding and control of matter at the nanoscale, at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications.
