Nanoparticle technique detects Alzheimer's-related proteins
Abstract:
"We have demonstrated the first diagnostic test for the potential Alzheimer's biomarker known as an ADDL," said Chad Mirkin, director of Northwestern's Institute for Nanotechnology. "This protein is only 5 nm wide and present in cerebrospinal fluid at very low concentration, making it difficult to detect. Our bio-barcode-amplification technology, which is a million times more sensitive than any other diagnostic technology, can accurately identify ADDLs even in CSF."
The bio-barcode-amplification technique uses 30 nm-diameter gold nanoparticles and magnetic microparticles.
