Gnat-sized robots, microscopic gyroscopes, television beamed directly onto your retina. This may sound like a grocery list for a crazed sci-fi visionary. But all these projects are in the works today, thanks to an emerging chip technology known as microelectromechanical systems. While magical microbots may still be a few years away, MEMS […]

Future nanomanufacturing processes will rely on two basic principles: a combination of chemical synthesis and self-assembly on one hand and robotic nanofabrication on the other. While the former is a controlled ‘natural’ process relying on chemistry and self-organization principles of nature (read more: How falling spaghettis could lead to more complex nanotechnology self-assembly), the latter […]

SiC MEMS Pressure Sensors: Technology, Applications and Markets
Silicon Carbide: Material Platform for Harsh Environment Solutions Silicon carbide (SiC) has been used for many conventional applications that require mechanical and chemical stability at high temperatures. Mechanical stability is defined as the ability of a particular material to preserve its mechanical properties – elasticity, fracture toughness, hardness […]

The biggest impediments to widespread adoption of photovoltaic cells as a routine source of energy are the cells’ inadequate efficiency and high cost. According to EE Times, IBM has taken a major step toward removing those barriers. Critical to the new development is the devices’ cooling mechanism, which employs a liquid metal layer of gallium […]

The same nanotech approaches being explored to deliver drugs exactly to the cells where they are needed also provide a technology base that might lead to permanent enhancements of human metabolism. Excerpts from “Cell ‘organs’ get plastic upgrades“, by Tamsin Osborne at NewScientist.com news service:
Human cells could have their metabolisms upgraded without altering their […]

A major advantage of nanotech drug delivery is that multiple drug molecules can be combined on one nanoparticle so that one nanoparticle binds more strongly to the drug target than would the isolated drug molecules. Attaching 12 molecules of an HIV drug to a 2.0 nm diameter gold nanoparticle enabled the drug to prevent HIV […]
