Sandia National Laboratories (www.sandia.gov) has designed a microdevice that can easily collect and release proteins in aqueous solution in less than one second. The device is a series of gold-coated lines, each line apart by a thickness of one-third of a human hair. It separates proteins from the solution and from each other by electrically heating the metal lines which warms a 4 nm-thick polymer film. The film then changes from a hydrophilic to a hydrophobic state, which enables the film to absorb proteins passing over it. The proteins now separated from the water molecules, are released in a natural cleansing action in the hydrophilic state.
As manufacturers add new technologies to their products, designing for compliance becomes more difficult. Prepare for the certification testing process. Otherwise, you increase the risk of discovering a safety issue after a product leaves the assembly line. That will cause significant time-to-market delays, be much costlier to fix, and damage your brand in the eyes of customers.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
