摘要

Sol-gel matrix GA was produced by hydrolyzing and polymerizing a mixture of GPTMS and APTMS. Sol-gel GA was used to entrap CdSe/ZnS quantum dots (QDs) to fabricate a QD-entrapped sol-gel membrane. The electronic energy transfer from the sol-gel GA membrane and QDs to protoporphyrin IX (PpIX) led to an increase in the energy absorption of PpIX. The QD-entrapped sol-gel membrane was used for quantification of PpIX in aqueous solution with a linear detection range of 1-50 mu M, and the sensitivity increased by about 25-44%, relative to that of the QD probes.
