A research team at the Air Force Research Laboratory’s 711th Human Performance Wing in Ohio has invented a device that helps study nanotoxicity.

Why? Because nanoparticles are being used in a wide range of applications, and the Air Force’s research team believes it is critical to proactively investigate their toxicity.

But to conduct the nanotoxicity investigations, chemists and medical researchers need to test the toxicity of nanoparticles with in vitro studies on live cells.

Air Force researchers Saber Hussain, and Christin and James Grabinski, from the Biomolecular Interactions of Nanomaterials Group, invented such a device that is capable of precisely delivering a consistent nanomaterial dose to a biological surface.

The invention, called the In Vitro Nanoparticle Exposure System, has multiple exposure chambers that can hold porous membrane insert along with cell culture media.

Aerosolized and charged nanomaterials are drawn into the chambers and laid onto the media using electrostatic deposition.

And the device can be configured to closely simulate a natural environmental exposure or be used to precisely deposit nanoparticles onto nonbiological surfaces like a transmission electron microscopy grid.

Potential applications for the Air Force’s invention are academic or commercial research targeting nanomaterials especially for drug development, environmental health, and hospital air quality monitoring.

The Air Force filed for and received a patent in March 2017. TechLink is now marketing patent licenses to industry partners that would build and sell the device.
