Switch on or switch off: an optical DNA sensor based on poly(p-phenylenevinylene) grafted magnetic beads.


There has been an enormous demand for commercial label-free DNA sensors in a diverse range of fields including pre-emptive medicine, diagnostics, environmental monitoring, and food industry. Addressing the need for sensitive, selective and facile DNA sensors, we demonstrate a novel switch on/off sensor design that utilizes sandwich hybridization between… (More)
