Nanotechnology In Water Treatment ... Due to their unique activity toward recalcitrant contaminants many nanomaterials are under active research and development for use in the treatment of water. Detection of microbial pathogens An adequate supply of safe drinking water is one of the major prerequisites for a healthy life, but waterborne diseases is still a major cause of death in many parts of the world, particularly in young children, the elderly, or those with compromised immune systems...

Molecular Self-assembly ... There are two types of self-assembly, intramolecular self-assembly and intermolecular self-assembly. Most often the term molecular self-assembly refers to intermolecular self-assembly, while the intramolecular analog is more commonly called folding...

Nanoparticle ... Nanoclusters have at least one dimension between 1 and 10 nanometers and a narrow size distribution. Nanopowders are agglomerates of ultrafine particles, nanoparticles, or nanoclusters...

Transhumanism ... The contemporary meaning of the term transhumanism was foreshadowed by one of the first professors of futurology, FM-2030, who taught "new concepts of the Human" at The New School of New York City in the 1960s, when he began to identify people who adopt technologies, lifestyles and world views transitional to "posthumanity" as "transhuman". This hypothesis would lay the intellectual groundwork for the British philosopher Max More to begin articulating the principles of transhumanism as a futurist philosophy in 1990, and organizing in California an intelligentsia that has since grown into the worldwide transhumanist movement...

Molecular Nanotechnology ... In August 2005, a task force consisting of 50+ international experts from various fields was organized by the Center for Responsible Nanotechnology to study the societal implications of molecular nanotechnology...

As nanotechnology is an emerging field, there is great debate regarding to what extent nanotechnology will benefit or pose risks for human health...

There's Plenty Of Room At The Bottom ... Feynman also suggested that it should be possible, in principle, to make nanoscale machines that "arrange the atoms the way we want", and do chemical synthesis by mechanical manipulation. He also presented the "weird possibility" of "swallowing the doctor," an idea which he credited in the essay to his friend and graduate student Albert Hibbs...

Drexler–Smalley Debate On Molecular Nanotechnology ... The debate is often cited in the history of nanotechnology due to the fame of its participants and its commentary on both the technical and social aspects of nanotechnology... Eric Drexler was the first person to develop the concepts of nanotechnology and was a key figure in popularizing these concepts...

Green Nanotechnology ... In addition to making nanomaterials and products with less impact to the environment, Green Nanotechnology also means using nanotechnology to make current manufacturing processes for non-nano materials and products more environmentally friendly... The second goal of Green Nanotechnology involves developing products that benefit the environment either directly or indirectly... Green Nanotechnology takes a broad systems view of nanomaterials and products, ensuring that unforeseen consequences are minimized and that impacts are anticipated throughout the full life cycle...

Technological Singularity ... This hypothesized process of intelligent self-modification might occur very quickly, and might not stop until the agent's cognitive abilities greatly surpass that of any human. The term "intelligence explosion" is therefore sometimes used to refer to this scenario...

DNA ... DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. These two strands run in opposite directions to each other and are therefore anti-parallel...

Energy Applications Of Nanotechnology ... People in the fields of science and engineering have already begun developing ways of utilizing nanotechnology for the development of consumer products... Benefits such as these make the investment of capital in the research and development of nanotechnology a top priority...

Nanomaterials ... An important aspect of nanotechnology is the vastly increased ratio of surface area to volume present in many nanoscale materials, which makes possible new quantum mechanical effects...

DNA Nanotechnology ... The conceptual foundation for DNA nanotechnology was first laid out by Nadrian Seeman in the early 1980s, and the field began to attract widespread interest in the early to mid 2000s... Fundamental concepts Properties of nucleic acids The goal of nanotechnology is to construct materials and devices with features on a scale less than 100 nanometers...
