A sensor for characterising aqueous solutions of hydrogen peroxide is described. The sensor is based on the calorimetric signal obtained when catalysing the decomposition of H(2)O(2). The system is quick and simple, and ...

The localised surface plasmon resonance in gold nanoparticles can be used as the basis of a refractometric sensor. Usually, this is accomplished by monitoring a shift in wavelength of the resonance peak, a task which ...
