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...
متن کاملTime-Resolved Luminescence Microscopy and Microarray Using Europium Chelate Labels
The luminescent Eu complex, DTBTA-Eu, is highly stable in terms of ligand-metal dissociation, and can be labelled to amino groups of proteins and other bio-molecules. Owing to the long lifetime of Eu luminescence, time-resolved measurement of DTBTA-Eu removes background fluorescence and enhances the sensitivity of the labelled materials. This property was applied to time-resolved luminescence m...
متن کاملTime-Resolved Luminescence Detection and Imaging Promises a Bright Future
Fluorescence/phosphorescence (referred in this article simply as luminescence) based-detections arguably are the most widely used detection technique for biological assays, imaging, and sensing. This is primarily due to its high detection sensitivity and the commercial availability of a large number of fluorescence probes [1-3]. Key to the usefulness of luminescence methods is the ability to se...
متن کاملOptically stimulated luminescence in synthetic quartz
Optically stiniulated luminescence (OSL). has been studied in synthetic quartz crystals. which had previously been exposed to Jtor X-irradiations. The main emission hands appeared at 380 and -~440 nm. The excitation spectra of these emission bands were now measured and showed both a maximum at 330nm. This maximum coincides with an excitation maximum of the phototransferred thermoluminescence (P...
متن کاملTime-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.
