When COVID-19 started sweeping across America in the spring of 2020, Irene Bosch knew she was in a unique position to help.
The Harvard-trained scientist had just developed quick, inexpensive tests for several tropical diseases, and her method could be adapted for the novel coronavirus. So Bosch and the company she had co-founded two years earlier seemed well-suited to address an enormous testing shortage.
E25Bio — named after the massive red brick building at MIT that houses the lab where Bosch worked — already had support from the National Institutes of Health, along with a consortium of investors led by MIT.
Within a few weeks, Bosch and her colleagues had a test that would detect coronavirus in 15 minutes and produce a red line on a little chemical strip. The factory where they were planning to make tests for dengue fever could quickly retool to produce at least 100,000 COVID-19 tests per week, she said, priced at less than $10 apiece, or cheaper at a higher scale.
Bosch’s prototype attracted a top Silicon Valley venture capital firm, which pitched in $2 million.
