Could detecting cancer one day be as easy as taking a blood test? Wei-Chuan Shih, a University of Houston researcher and Cullen College of Engineering professor of electrical and computer engineering, has reported a 98.7-percent rate of accuracy for a method pioneered by his lab to identify cancers at their earliest stages.

The technology combines Shih’s own PANORAMA (PlAsmonic NanO-apeRture lAbel-free iMAging) with fluorescent imaging to view nanometer-sized membrane sacs, called extracellular vesicles or EVs. EVs carry different types of cargo, including proteins, nucleic acids and metabolites, throughout the bloodstream.

“We observed differences in small EV numbers and cargo in samples taken from healthy people versus people with cancer and are able to differentiate these two populations based on our analysis of the small EVs,” reports Shih, in Nature Communications Medicine. “The findings came from combining two imaging methods – our previously developed method PANORAMA and imaging of fluorescence emitted by small EVs—to visualize and count small EVs, determine their size and analyze their cargo.”

Shih introduced PANORAMA in 2020. The technology uses a glass side covered with gold nano discs that allows users to monitor changes in the transmission of light as well as determine the characteristics of nanoparticles as small as 25 nanometers in diameter. For the new publication, Shih and his team just had to count the number of small EVs in order to detect cancer.

“Using a cutoff of 70 normalized small EV counts, all cancer samples from 205 patients were above this threshold except for one sample, and for healthy samples, from 106 healthy individuals, all but three were above this cutoff, giving a cancer detection sensitivity of 99.5% and specificity of 97.3%,” says Shih.

The team was able to report 100-percent accuracy with further testing that analyzed two independent sets of samples from stage I-IV or recurrent leiomyosarcoma/gastrointestinal stromal tumors and early-and-late-stage cholangiocarcinoma combined with healthy samples.

Shih and collaborator Steven H. Lin have founded Seek Diagnostics with the goal of commercializing the technology that they’ve innovated. In 2022, the duo joined the Texas Medical Center Innovation's cancer-focused accelerator.

Two researchers at the University of Houston have been named to the inaugural class of senior members for the National Academy of Inventors. The new distinction recognizes the honorees for fostering innovation and educating and mentoring future innovators — as well as their contribution to science and technology.

The two UH honorees are Mark Clarke, associate provost for faculty development and faculty affairs, and Wei-Chuan Shih, associate professor of electrical and computer engineering. Both will be recognized at the eighth annual NAI meeting in Houston this April, a release from UH says.

"Dr. Clarke and Dr. Shih both have impressive records of producing impactful intellectual property and spurring innovation that is pertinent to the Houston region," Amr Elnashai, vice president of research and technology at UH, says in the release. "Their further efforts, including helping UH faculty commercialize technologies as well as working with graduate and undergraduate students to boost their entrepreneurial efforts, are a critical contribution to building the region's innovation ecosystem."

NAI named 65 total scientists from 37 universities as senior members. The scientists have been named on over 1,100 patents issued in the United States. Ten other Texas scientists made the inaugural class, representing Texas Tech university, Texas A&M University, Baylor College of Medicine, and University of Texas at Arlington.

The organization also has a fellowship program, in which UH has 12 current fellows.

Clarke has been at UH for over a decade and previously held the position of associate vice chancellor/vice president for technology transfer at the UH Division of Research, where he oversaw a portfolio of 360 technology patents, according to the release. Clarke has 13 patents to his name and previously worked at two startups — both commercialized technologies Clarke developed in his tenure at NASA then UH.

UH's other senior NIA member, Shih, has been granted 11 patents in the US. His NanoBioPhotonics Group has developed a number of sensing and imaging technologies and devices for biomedicine and environmental testing, among other fields. Shih, who has been at the university for over nine years, created a startup with a group of students called DotLens. The company produced and distributed lenses that could be used to convert a smartphone into a microphone.

A few months ago, a Houston scientist received international recognition when he

won the Nobel Prize for the cancer research he did for the University of Texas MD Anderson Cancer center. Jim Allison won for his work in launching an effective new way to attack cancer by treating the immune system rather than the tumor.

Houston startup expands DOD partnership to provide clean energy at Texas site

seeing green

Expanding on its partnership with the United States Department of Defense's Defense Innovation Unit, Sage Geosystems has been selected to conduct geothermal project development initiatives at Naval Air Station in Corpus Christi.

Along with the Environmental Security Technology Certification Program, Sage will provide its proprietary Geopressured Geothermal Systems technology, will be able to evaluate the potential for geothermal baseload power generation to provide clean and consistent energy at the Naval Air Station base.

“We’re pleased to expand our partnership with the DOD at NAS Corpus Christi to demonstrate the advantages of geothermal technology for military energy independence,” Cindy Taff, CEO of Sage Geosystems, says in a news release.

Sage is also conducting initiatives at Fort Bliss and has completed an analysis at the Ellington Field Joint Reserve Base. The analyses could “pave the way for expanding geothermal energy solutions across additional U.S. military installations,” according to Sage.

The company’s proprietary technology works by leveraging hot dry rock, which is a more abundant geothermal resource compared to traditional hydrothermal formations, and it provides energy resilience for infrastructures. In addition, Sage is building a 3 megawatt commercial EarthStore geothermal energy storage facility in Christine, Texas, which is expected to be completed by December. Sage also announced a partnership with Meta Platforms. With Meta Platforms, Sage will deliver up to 150 megawatt of geothermal power generation east of the Rocky Mountains.

The Naval Air Station Corpus Christi is considered a critical training and operations hub for the U.S. Navy, and the partnership with Sage shows the Navy's commitment to achieving net-zero carbon emissions by 2045. Sage’s technology will be assessed for its ability to create a microgrid, which can reduce reliance on the utility grid and ensure power supply during outages.

“As we advance our Geopressured Geothermal Systems, we see tremendous potential to not only provide carbon-free power, but also strengthen the operational capabilities of U.S. military installations in an increasingly digital and electric world,” Taff adds.

In September, the Air Force awarded Sage a grant of $1.9 million in a first-of-its kind contract to determine whether a power plant using Geopressured Geothermal Systems is able to generate clean energy needed for a base to achieve energy resilience.
