Time Resolved Fluorescence of CdSe Nanocrystals

Lanthanide-based time-resolved luminescence immunoassays

The sensitive and specific detection of analytes such as proteins in biological samples is critical for a variety of applications, for example disease diagnosis. In immunoassays a signal in response to the concentration of analyte present is generated by use of antibodies labeled with radioisotopes, luminophores, or enzymes. All immunoassays suffer to some extent from the problem of the backgro...

Time-resolved luminescence of semiconductor heterostructures in high magnetic fields

We report on time-resolved luminescence in GaAs quantum wells in high magnetic fields up to 21 T. Results on resonant tunneling and exciton relaxation including spin flip are presented.

Time-resolved luminescence studies of heavily nitrogen doped ZnSe

Time-resolved luminescence data from heavily nitrogen doped ZnSe ~total N concentration exceeding mid-10/cm) is presented. The luminescence exhibited a decay time and a rise time which increased with decreasing energy of observation. Furthermore, both the decay times and rise times decreased with increasing temperature. These observations are consistent with the following model: ~i! a band of s...

Time-resolved detection of lanthanide luminescence for ultrasensitive bioanalytical assays.

The principles and practice of the application of time-resolved lanthanide chelate luminescence (or fluorescence) as a detection method for ultrasensitive bioanalytical assays such as immunoassays and nucleic acid hybridization assays are reviewed. The various lanthanide chelate-based detection systems which have been developed for use in heterogeneous and homogeneous assay formats are describe...
