3D Printed Lung Tissue Used to Analyze the Impact of Toxic Fumes on Humans

Throughout the day, we are surrounded by a variety of odors, some of which can be harmful to our health. Indeed, chemicals such as ammonia and chlorine can be particularly dangerous. The people most at risk are those who work in ports and factories, where incidents can occur. These two substances are still among the most widely transported in the USA in particular, making their management and handling delicate and potentially dangerous.

To better understand the hazards associated with certain chemicals, the Science & Technology Division of the U.S. Department of Homeland Security and its Chemical Safety Analysis Center (CSAM) have collaborated with the Wake Forest Institute for Regenerative Medicine (WFIRM). Together, they are working to reduce the effects of exposure to these substances. They have developed 3D-printed human lung cells and tissues on microchips to be used for in-depth studies on what is harmful to our health.

3D Printing to Recreate and Study Lung Tissue

Theresa Pennington, project manager, emphasizes the importance of their research: “The Organ-on-a-Chip studies that we are conducting with our partners at the Wake Forest Institute are incredibly important.” Indeed, Wake Forest’s 3D printer for organic lung tissue marks a great advance on traditional methods.
