Improvement in Fingerprint Detection Using Tb(iii)-dpicolinate Complex Doped Nanobeads and Time Resolved Imaging
This paper deals with the synthesis and application of lanthanide complex doped nanobeads used as a luminescent fingerprint powder. Due to their special optical properties, namely a long emission lifetime, sharp emission profiles and large Stokes shifts, luminescent lanthanide complexes are useful for discriminating against signals from background emissions. This is a big advantage because late...
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 کاملDipicolinic acid (DPA) assay revisited and appraised for spore detection.
Delayed gate fluorescence detection of dipicolinic acid (DPA), a universal and specific component of bacterial spores, has been appraised for use in a rapid analytical method for the detection of low concentrations of bacterial spores. DPA was assayed by fluorimetric detection of its chelates with lanthanide metals. The influence of the choice and concentration of lanthanide and buffer ions on ...
متن کاملThe time domain in co-stained cell imaging: time-resolved emission imaging microscopy using a protonatable luminescent iridium complex.
The intense luminescence of the new complex Ir(ppy)(2)(pybz) (1) within the cytoplasm of live cells can be discriminated from the fluorescence of an organic stain, solely on the basis of the emission timescale {pybzH = 2-pyridyl-benzimidazole}. The protonated form of 1 displays red-shifted emission, and may be implicated in a superior uptake compared to Ir(ppy)(3).
متن کاملComputational time-resolved imaging
Classical photography uses steady-state illumination and light sensing with focusing optics to capture scene reflectivity as images; temporal variations of the light field are not exploited. This thesis explores the use of time-varying optical illumination and time-resolved sensing along with signal modeling and computational reconstruction. Its purpose is to create new imaging modalities, and ...
