Safe and rapid development of advanced materials : a research case study for safe development of nanoenabled environmental sensors

The enhanced understanding of nanomaterials properties and processing has led to increased use of nanotechnologies, which has also led to greater scrutiny on the commercialization and acquisition of emerging nanoenabled technologies. Caused by knowledge gaps on the unique behaviors, risks, and liabilities of novel engineered nanomaterials, this caution, when not evidence based, slows production and stifles innovation. Reducing the uncertainty surrounding the environmental risks and benefits of nanoenabled technologies, including their resilience in harsh environments, will speed the development and transition of advanced material technologies. In this work, a multifaceted research program generated data and processes to reduce that environmental uncertainty. Specifically, this case study examined printed, nanoenabled environmental sensors and their components to develop toxicological data and parameterize a life-cycle assessment. The study tested the sensors’ resilience in environmental weathering studies that considered both the potential release of the ingredient nanomaterials and the performance of the sensors after exposure to several harsh environmental climates and then created life-cycle inventories to determine environmental impact and reduce cost of research and development. Finally, this case study developed software tools to mitigate the cost of research and provide a framework for presenting toxicology data.
