Novel biosensor offers enhanced DNA detection specificity

Researchers have successfully demonstrated a novel biosensor capable of detecting single-stranded DNA oligonucleotides with high specificity without needing external labels. This advancement paves the way for more accessible and efficient point-of-care diagnostics. The study, reported in Engineering, is titled "Development of an Integrated CMUTs-based Resonant Biosensor for Label-Free Detection of DNA with Improved Selectivity by Ethylene-Glycol Alkanethiols."
