Scientists create sensors with traps for free radicals
(PHYSorg.com Chemistry)

Scientists of Tomsk Polytechnic University and partners from the Czech Republic and France have designed extremely sensitive sensors for free oxygen-containing radicals that are able to disrupt cell function. According to the researchers, these sensors are an alternative to traditional analytical chemical methods of analysis. The laboratory tests demonstrated that its sensitivity is higher by four orders of magnitude. This was achieved due to the effect of surface plasmon resonance in combination with `traps` of organic compounds. The results are published in Sensors and Actuators B: Chemical.
