A chemiluminescence sensor with signal amplification based on a self-immolative reaction for the detection of fluoride ion at low concentrations

摘要

Abstract A sensory system incorporated with an amplification function was developed for the detection of trace-level fluoride ions. This sensory system comprises two steps: amplification and chemiluminescence. These steps were linked with chemical reactions and were induced continuously. The process from amplification to chemiluminescence was accomplished in this system using fluoride ions. The amplification is based on a self-immolative system that permits the detection of emissions even at low fluoride ion concentrations for systems in which chemiluminescence cannot be induced in the absence of fluoride ions. The optimal ratio of the chemiluminescent compound and the amplifier was calculated to achieve efficient amplification. Graphical abstract Display Omitted ]]>
