Rapid Disease Detection through Coffee-Ring Impact Technology in a 12-minute Timeframe
A groundbreaking diagnostic technology, developed by scientists at the University of California, Berkeley, is set to revolutionise the field of healthcare. This innovative approach, which utilises the physics behind coffee rings, could potentially make tests faster, cheaper, and more accessible for a wide range of conditions, including COVID-19 and sepsis.
The technology is based on the coffee-ring effect, a phenomenon that occurs when a liquid evaporates, leaving behind a ring of residue. In this case, the residue is disease-related proteins, nucleic acids, or viral particles, which are concentrated at the edge of the ring. This physical principle allows for enhanced detection sensitivity by localising disease markers from a sample onto a small area, making it easier to analyse even trace amounts of target molecules.
The diagnostic test works by concentrating disease-related proteins at the edge of a ring pattern and using plasmonic nanoparticles to create light patterns that can be identified visually or through a smartphone. This rapid test is up to 100 times more sensitive than current at-home COVID-19 tests and does not require complex equipment or lab facilities.
The UC Berkeley team's innovation combines the coffee-ring effect with plasmonic nanoparticles and an AI-powered app to detect disease biomarkers. The app guides users in placing the sample and plasmonic droplets accurately, ensuring the test's accuracy.
The test can potentially detect life-threatening conditions like sepsis and prostate cancer in just 12 minutes. The technology pre-concentrates disease biomarkers into a ring pattern to boost its sensitivity, enabling fast, point-of-care diagnostics by concentrating viral proteins or nucleic acids without the need for extensive sample preparation or amplification steps.
The development of this technology could potentially revolutionise the field of diagnostics, making tests faster, cheaper, and more accessible. The technology is designed for at-home use, making it more accessible to a wider population. The findings have been published in the journal Nature Communications, and a prototype home testing kit has already been developed.
This approach is detailed in recent biomedical research where Surface-Enhanced Raman Spectroscopy (SERS) combined with the coffee-ring effect has been used to detect nucleic acids, proteins, and other disease-related molecules with high specificity and sensitivity, suitable for liquid biopsy and rapid diagnostics applications. The effect's ability to localise biomarkers improves signal detection and reduces sample volume requirements, making it promising for rapid tests in infectious diseases including COVID-19.
In conclusion, this new diagnostic approach uses the coffee-ring effect to physically concentrate biomarkers from a small droplet onto a confined surface area, followed by enhanced spectroscopic detection methods like SERS for quick, sensitive, and specific disease detection, enabling fast diagnostics for COVID-19 and other conditions. This could potentially improve treatment outcomes and save lives by enabling early detection of diseases.
