A Silicon Valley startup with Houston roots is helping tackle the COVID-19 pandemic with its smartphone-based coronavirus test.

Milpitas, California-based Luminostics, a University of Houston spinout, is producing millions of its Clip COVID Rapid Antigen Test for U.S. consumers after receiving emergency authorization for the product in December. The emergency approval closely followed the National Institutes of Health awarding a $26.1 million contract to Luminostics to speed up development of the coronavirus test. According to a news release from UH, Luminostics is working on an affordable next generation hardware system to reach the mass over-the-counter market at scale.

Chemical engineers and UH alumni Bala Raja, the CEO, and Andrew Paterson, the chief technology officer, began forming their company in the UH lab of Richard Willson, a professor of chemical and biomolecular engineering and professor of biochemical and biophysical sciences.

The technology developed in the UH lab aims to equip consumers with rapid self-diagnostic tests for the flu, HIV, herpes, and other conditions by detecting the presence of bacteria, viruses, small molecules, hormones, and proteins. But Raja and Paterson put that strategy on hold last year and pivoted to re-engineering their technology for COVID-19 testing. The result: the Clip COVID Rapid Antigen Test.

"When we realized that COVID wasn't just a bad flu and that it was actually gonna go crazy and affect as many people as it has, we decided that everything we've done could be very quickly repurposed to make two different tests," Raja told Inc. magazine in April.

As UH explains, the Clip COVID test relies on a nasal swab, a smartphone clip, and glow-in-the-dark nanoparticles to detect a coronavirus infection within 30 minutes. In the phone, an image processor measures the intensity of the luminescence signal. If the signal is strong enough, the result is positive. If it's weak, the result is negative.

"We live in a world where you can have all your basic necessities delivered to your home through an app, and yet this pandemic has exposed how far behind the diagnostics industry lags compared to consumer technology and the convenience economy," Paterson tells UH.

Funding from the National Institutes of Health, venture capital firm Khosla Ventures, investment firm Lynette Capital, and startup accelerator Y Combinator has helped support the Clip COVID Rapid Antigen Test. The startup entered the Y Combinator program in 2016, a year after Raja and Paterson established Luminostics.

In April 2020, French pharmaceutical giant Sanofi said it was exploring a collaboration with Luminostics on the COVID-19 test.

"The diagnostics industry is saturated with products that cater to big, centralized labs or testing in the doctor's office," Paterson says. "There are many applications where it does make sense to do testing in a centralized lab, but there are dozens of other applications where there should be home-tests and there are not, because few companies have tried to take on the technical and regulatory challenges with developing home-testing."

Venus Aerospace picks up investment from Lockheed Martin Ventures

space funding

Venus Aerospace, a Houston-based startup specializing in next-generation rocket engine propulsion, has received funding from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, for an undisclosed amount. The product lineup at Lockheed Martin includes rockets.

The investment follows Venus’ successful high-thrust test flight of its rotating detonation rocket engine (RDRE) in May. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

Venus says the Lockheed Martin Ventures investment reflects the potential of Venus’ dual-use technology for defense and commercial uses.

“Venus has proven in flight the most efficient rocket engine technology in history,” Venus co-founder and CEO Sassie Duggleby, a board member of the Texas Space Commission, said in a news release. “With support from Lockheed Martin Ventures, we will advance our capabilities to deliver at scale and deploy the engine that will power the next 50 years of defense, space, and commercial high-speed aviation.”

Chris Moran, executive director and general manager of Lockheed Martin Ventures, said Lockheed Martin has been a longtime supporter of early-stage “transformational” technologies.

“Our investment in Venus Aerospace reflects a conviction that next-generation propulsion will define which nations lead in space and defense for decades to come,” Moran added in the release. “We are committed to helping Venus scale this technology and integrate it into critical systems.”

Since its founding in 2020, Venus has secured more than $106 million in funding. In addition to Lockheed Martin Ventures, investors include Airbus Ventures, America’s Frontier Fund, Trousdale Ventures, and Prime Movers Lab. Supporters of Venus include NASA, the Air Force Research Lab and the Defense Advanced Research Projects Agency (DARPA).
