Detection of nanomolar concentrations of copper (II) with a Tb- quinoline-2-one probe using luminescence quenching or luminescence decay time

We present a time-resolved (gated) luminescence-based method for determination of Cu2+ ions in microtiterplate format in the nanomolar concentration range using the novel long lived terbium complex.

pH responsive sol-gel hybrid material doped with colorimetric sulfonephthalein pH indicators

Optical pH sensing offers numerous advantages over conventional electrochemical techniques, for example, immunity to electrical interferences, ease of miniaturization and the possibility of remote sensing and in vivo measurement. In this work, we have studied the effects of epoxy-modification of silicate matrices containing entrapped pH sulfonephthalein colorimetric indicators as functional inorganic-organic hybrid materials. The developed sensors based on the hybrid sol-gel matrixes have dynamic pH ranges that are amenable to applications, such as environmental monitoring and bioprocessing.
