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."

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

FAA demands investigation into SpaceX's out-of-control Starship flight

Out of this world

The Federal Aviation Administration is demanding an accident investigation into the out-of-control Starship flight by SpaceX on May 27.

Tuesday's test flight from Texas lasted longer than the previous two failed demos of the world's biggest and most powerful rocket, which ended in flames over the Atlantic. The latest spacecraft made it halfway around the world to the Indian Ocean, but not before going into a spin and breaking apart.

The FAA said Friday that no injuries or public damage were reported.

The first-stage booster — recycled from an earlier flight — also burst apart while descending over the Gulf of Mexico. But that was the result of deliberately extreme testing approved by the FAA in advance.

All wreckage from both sections of the 403-foot (123-meter) rocket came down within the designated hazard zones, according to the FAA.

The FAA will oversee SpaceX's investigation, which is required before another Starship can launch.

CEO Elon Musk said he wants to pick up the pace of Starship test flights, with the ultimate goal of launching them to Mars. NASA needs Starship as the means of landing astronauts on the moon in the next few years.

TMC med-tech company closes $2.5M series A, plans expansion

fresh funding

Insight Surgery, a United Kingdom-based startup that specializes in surgical technology, has raised $2.5 million in a series A round led by New York City-based life sciences investor Nodenza Venture Partners. The company launched its U.S. business in 2023 with the opening of a cleanroom manufacturing facility at Houston’s Texas Medical Center.

The startup says the investment comes on the heels of the U.S. Food and Drug Administration (FDA) granting clearance to the company’s surgical guides for orthopedic surgery. Insight says the fresh capital will support its U.S. expansion, including one new manufacturing facility at an East Coast hospital and another at a West Coast hospital.

Insight says the investment “will provide surgeons with rapid access to sophisticated tools that improve patient outcomes, reduce risk, and expedite recovery.”

Insight’s proprietary digital platform, EmbedMed, digitizes the surgical planning process and allows the rapid design and manufacturing of patient-specific guides for orthopedic surgery.

“Our mission is to make advanced surgical planning tools accessible and scalable across the U.S. healthcare system,” Insight CEO Henry Pinchbeck said in a news release. “This investment allows us to accelerate our plan to enable every orthopedic surgeon in the U.S. to have easy access to personalized surgical devices within surgically meaningful timelines.”

Ross Morton, managing Partner at Nodenza, says Insight’s “disruptive” technology may enable the company to become “the leader in the personalized surgery market.”

The startup recently entered a strategic partnership with Ricoh USA, a provider of information management and digital services for businesses. It also has forged partnerships with the Hospital for Special Surgery in New York City, University of Chicago Medicine, University of Florida Health and UAB Medicine in Birmingham, Alabama.
