Biomedical engineers at Duke University have devised a method that uses nanoparticles called gold nanostars to simultaneously detect the presence of multiple specific microRNAs in RNA extracted from tissue samples without the need for labeling or target amplification. The technique could be used to identify early biomarkers of cancer and other diseases without the need for the elaborate, time-consuming, and expensive processes required by current technologies.
