Revolutionary Device Detects Brain Cancer In Under 60 Minutes

Cancer

Researchers at the University of Notre Dame have developed a revolutionary device capable of diagnosing glioblastoma, a particularly aggressive and currently incurable form of <span>brain <a href="https://www.healthandme.com/health/cancer">cancer</a></span>, in just 60 minutes. This automated diagnostic tool represents a significant advancement in <span>cancer detection</span>, with the potential to drastically improve early diagnosis and patient outcomes.

<h2>What is Glioblastoma?</h2>Glioblastoma is one of the deadliest forms of brain <span>cancer</span>, with patients typically facing a survival period of only 12 to 18 months following diagnosis. Early detection is crucial for improving survival rates, as this cancer is notoriously difficult to diagnose in its early stages. Symptoms of glioblastoma can include persistent headaches, nausea, seizures, and changes in cognitive abilities. Traditional diagnostic methods, including imaging and biopsies, can be time-consuming and costly, often delaying treatment.

<h2>How Does The New Device Detect Cancer?</h2>

The innovative device developed by Notre Dame researchers utilizes a biochip designed to detect specific biomarkers associated with glioblastoma. Key to this technology is its ability to identify active Epidermal Growth Factor Receptors (EGFRs), which are often found in high concentrations in glioblastoma cells. These receptors are detected through extracellular vesicles—tiny particles released by cells that carry important biological information.

Lead researcher Hsueh-Chia Chang, the Bayer Professor of Chemical and Biomolecular Engineering, explains, "Extracellular vesicles, or exosomes, are nanoparticles secreted by cells, which are significantly larger than molecules and weakly charged. Our technology is specifically designed to leverage these properties."

The team faced challenges in distinguishing between active and inactive EGFRs and ensuring the accuracy and precision of their diagnostic tool. They addressed these issues by developing a small, cost-effective electrokinetic sensor that enhances sensitivity and reduces interference. This sensor detects active EGFRs by measuring voltage changes caused by interactions with synthetic particles, allowing for rapid and reliable detection.

The device comprises three main components: an automation interface, a portable prototype machine, and the biochip. Each test requires only 100 microlitres of blood and costs under $2 (Rs 168) in materials. While initially designed for glioblastoma, the researchers are optimistic that the technology could be adapted for diagnosing other diseases such as pancreatic cancer, cardiovascular conditions, dementia, and epilepsy.

The device has been validated using blood samples from the Centre for Research in Brain Cancer at the Olivia Newton-John Cancer Research Institute in Melbourne, Australia. Dr. Chang emphasizes the broader potential of this technology, noting, "Our technique is particularly suited to glioblastoma due to its deadliness and the lack of early screening tests. We hope this technology will pave the way for earlier detection and improved survival rates."

This breakthrough device marks a promising step towards more effective and timely diagnosis of brain cancer, potentially transforming how we approach the fight against this devastating disease.
