Revolutionary Nanowire Technology Enables Non-Invasive cfDNA Capture and Release from Urine

Researchers at Nagoya University in Japan have developed a technology to capture and release cell-free DNA (cfDNA) on nanowire surfaces from urine, allowing for the detection of genetic mutations associated with gliomas, a type of brain tumor. The technique overcomes the challenge of isolating cfDNA from urine samples and could potentially be used for early cancer detection. The researchers successfully detected the IDH1 mutation, a characteristic genetic mutation found in gliomas, from a small urine sample. This method opens up possibilities for detecting other types of tumor mutations that cannot be isolated by conventional methods.
