Research at Massachusetts Institute of Technology under Dr. Timothy Swager has led to chemical detection devices based on amplified fluorescence quenching of solid-state conjugated polymer films. The sensor consists of a glass capillary tube whose interior is coated with a polymer film comprised of a conjugated backbone with pentiptycene groups. In operation, the AFP polymer is excited to a fluorescent state using a light source external to the capillary tube. An air pump is then used to draw the sample through the capillary; compounds containing nitroaromatic groups (TNT, RDX, etc.) bind to the polymer, causing fluorescence to be quenched. The change in fluorescence is read as a change in response at a photometer positioned axially to the capillary. Because the polymer chains are electronically conjugated, binding at any point along the polymer chain results in complete quenching of all sites on the polymer. The effective amplification in response by this technique over monomeric quenching is estimated to be from 100X to 1000X.

Coronavirus evacuees return safely to U.S. via innovative, MRIGlobal-designed biocontainment system.

Fourteen U.S. citizens who tested positive for coronavirus are receiving medical treatment back home in the U.S. yesterday – and not thousands of miles away in Japan – partly in thanks to innovative technology by biocontainment and global health experts at MRIGlobal, based in Kansas City, Missouri.

As reported on international news, the citizens were evacuated on Monday from the Diamond Princess cruise ship, which had been quarantined off the coast of Japan for more than 10 days. The patients were evacuated in the safest manner to a specialized containment area on chartered evacuation aircraft to isolate them, using standard protocols, for medical care in coronavirus treatment centers in the U.S.

One of the specialized units was designed by MRIGlobal engineers through a private-public partnership with U.S. Department of State and the Paul Allen Foundation in response to the Ebola outbreak in 2014. The units are state-of-the-art, flight-ready containerized biocontainment systems (CBCS) that roll on and off planes. MRIGlobal designed the CBCS as a reusable bio-containment and medical treatment unit to operate on government/civilian cargo aircraft. The units can containerize highly contagious pathogens, are extremely durable and allow for the safe transport of critically ill patients while maintaining biocontainment and safe flight.

According to Dean Gray, Ph.D., Director at MRIGlobal, “We’re proud to play a part in helping to safely evacuate people out of harm’s way to locations where they can receive appropriate medical care.

“There’s nothing like the CBCS for flyable medical transport” added Gray. “It was developed to respond to critical global health situations like the coronavirus outbreak, and ultimately to save lives.”

To date, MRIGlobal has designed and delivered four CBCS units, which are in use by the U.S. government.

MRIGlobal’s state-of-the-art, flight-ready Containerized Biocontainment System (CBCS) was awarded an R&D100 Award for Innovation by R&D Magazine in 2016. Each year R&D Magazine presents the awards to 100 of the most technologically significant and innovative technologies introduced to the marketplace over the past year.
