A test that uses gold nanoparticles to detect early-stage prostate cancer costs less than $1, returns results in minutes and is more accurate than standard PSA screening, pilot studies show. The new technique leverages the ability of gold nanoparticles to attract cancer biomarkers. A test that costs less than a $1 and yields results in minutes has been shown in newly published studies to be more sensitive and more exact than the current standard test for early-stage prostate cancer. The simple test developed by University of Central Florida scientist Qun "Treen" Huo holds the promise of earlier detection of one of the deadliest cancers among men.
It would also reduce the number of unnecessary and invasive biopsies stemming from the less precise PSA test that's now used. "It's fantastic," said Dr. Inoel Rivera, a urologic oncologist at Florida Hospital Cancer Institute, which…
