Light shines for potential early cancer diagnosis technique
December 22nd, 2008
A team led by a Northwestern University biomedical engineer has developed a new optical technique that holds promise for minimally invasive screening methods for the early diagnosis of cancer.
The researchers have shown for the first time that nanoscale changes are present in cells extremely early on in carcinogenesis. Their technique, partial-wave spectroscopy (PWS), can detect subtle abnormal changes in human colon cancer cells even when those same cells appear normal using conventional microscopy.
The study is published online by the Proceedings of the National Academy of Sciences.
A simple yet sensitive method, PWS quantifies the...
