To help detect infectious diseases such as anthrax, HIV, and smallpox, researchers from Northwestern University developed a technique for creating DNA detection probes to "fingerprint" these biological agents. Attached to tiny gold particles are molecules that provide a unique signal (the "fingerprint") when a light is shined on them and a single strand of DNA designed to recognize and bind a target of interest. If a disease target is present in the sample being tested, strands of DNA bind to the appropriate spot on the chip. Corresponding nanoparticle probes latch onto any matches, which are then coated with silver. A laser scans the chip, and signals for the probes are recorded. A unique "fingerprint" can be designed for each biological agent. For more information, contact Chad Mirkin at firstname.lastname@example.org.
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
Hosted CAD or PDM systems is an emerging technology that offers many advantages over traditional on premise workstation CAD configurations and is making many companies rethink how to deliver future CAD software solutions.
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.
