GAINESVILLE, Fla., & NEW YORK, Nov. 30 —- University of Florida and Columbia University researchers say they are a step closer to a technique to easily detect a wide variety of cancers before symptoms become apparent. The findings involve introducing molecularly engineered strands of DNA into cell cultures and observing whether they unleash a fluorescent burst after they adhere to cancer proteins. The technique could enable doctors to search within extremely complex fluid or tissue samples to pinpoint biomarkers -— proteins that signal that something is wrong. “Even when the cancer...Read full articleRelated content from Photonics MediaArticlesAptamers Provide Instant Photonics-Based DiagnosticsAptamer-based diagnostics is a new field in the development of technologies for instantly identifying disease.
