Pratim Biswas, the Lucy and Stanley Lopata Professor and chair of the Department of Energy, Environmental & Chemical Engineering in the School of Engineering & Applied Science, along with doctoral students Jiaxi Fang and Tandeep Chadha, founded Applied Particle Technology (APT) in 2014. Their adviser, Emre Toker, is managing director of the Washington University Skandalaris Center for Interdisciplinary Innovation and Entrepreneurship.

In August, APT was one of 17 companies chosen to participate in the Cleantech Open Midwest accelerator, a 20-week program that gives entrepreneurs from 13 states the resources required to turn the startups into sustainable businesses that focus on energy, environmental and economic challenges.

APT provides air treatment systems in environments that require high efficiency removal of tiny particles. The innovative system, which operates without a media filter, can also inactivate pathogens and remove toxic fumes or odors. APT's technology could be used on commercial airplanes, in hospital clean rooms and in other areas where the highest standards of air quality must be maintained.

APT won a $50,000 Arch Grant in June and took second place in last year's Olin Cup competition, winning a $50,000 opportunity investment for the company. APT also was a finalist in the Massachusetts Institute of Technology Clean Energy Competition this year and was awarded a small cash prize and mentoring help for the startup.

The Cleantech Open Midwest organization, a division of the Cleantech Open network, was founded in 2010. The Midwest organization covers Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Missouri, Minnesota, Nebraska, North Dakota, Ohio, South Dakota and Wisconsin. Since inception, the Midwest programs have worked with more than 90 startup companies that have gone on to raise more than $20 million in external capital.


The School of Engineering & Applied Science at Washington University in St. Louis focuses intellectual efforts through a new convergence paradigm and builds on strengths, particularly as applied to medicine and health, energy and environment, entrepreneurship and security. With 88 tenured/tenure-track and 40 additional full-time faculty, 1,300 undergraduate students, more than 900 graduate students and more than 23,000 alumni, we are working to leverage our partnerships with academic and industry partners — across disciplines and across the world — to contribute to solving the greatest global challenges of the 21st century.
