摘要：
Studies to determine the concentration of hydrogen peroxide (H2O2) are important in biological system due to cellular damages provoked by reactive oxygen species that include H2O2. An alternative to detect H2O2 is through optical nanosensors based on silver nanoparticles, which have great potential for chemical and biological sensing applications. Here we demonstrate that attenuated total reflectance (ATR) from interaction of silver nanoparticles and hydrogen peroxide were able to detect very low levels of H2O2 around 0,001mM.
