Cellular transcriptional logic circuits
The TechnologyMoore's Law, stating that the number of transistors on integrated circuits doubles around every two years, has held up since his initial publication in 1965. Smaller chips provide lower cost and higher speed or processing power. As chips become ever smaller, new techniques for miniaturizing complex circuits must evolve. In the near future,...

Smart sense-and-respond bandage for the detection and treatment of wound infections
The TechnologyResearchers at The University of Tennessee have developed a sense-and-respond bandage for autonomous, closed-loop detection, communication, and self-mitigation of wound pathogens. Using an integrated genomic, biomedical, and nanotechnological approach, the inventors have engineered a biochip biosensor that detects the presence of bacterial...

Plant derived nanoparticles for cosmetics and sunscreen
The TechnologyThere are numerous sunscreen and cosmetics products on the market today that contain nanoparticles (NP’s). These NP’s increase ultraviolet light absorption of the product and also allow the product to be spread more easily. Titanium dioxide (TiO2) and Zinc oxide (ZnO) are the most commonly used NP’s, and they are commonly found together...

Bioluminescent fish for environmental detection, drug testing, and hobby collectors
The Technology Researchers at the University of Tennessee have developed transgenic luminescent zebrafish. The gene cassette used to create the luminescence can be engineered to express exclusively in the presence of a particular compound or pollutant in the zebrafish’s environment, thus functioning as a bioluminescent environmental reporter. The...

Mobile tracking device for medical applications (MTD)
The Technology Prior to the use of fluoroscopy, kinematics of human joints were assessed using cadavers or motion analyses systems. Unfortunately, cadaver testing does not allow for in vivo soft-tissue conditions to be present, and motion analyses systems induce significant out-of-plane error due to skin motion. Fluoroscopy does have advantages for...
