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 email@example.com.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
