Biodegradable microspheres are effective devices for controlled drug release, and it is desireable to be able to monitor their distribution in vivo in order to optimize delivery methods. Biodegradable microspheres coencapsulating Gd-DTPA and human vascular endothelial growth factor (VEGF) were made from poly(1actic-co-glycolic acid) (PLGA). The release of VEGF from the spheres was measured and ...
Lanthanide (Ln(III)) complexes form an important class of highly efficient luminescent materials showing characteristic line emission after efficient light absorption by the surrounding ligands. The efficiency is however lowered by back energy transfer from Ln(III) ion to the ligands, especially at higher temperatures. Here we report a new strategy to reduce back energy transfer losses. Nonanuc...
The aim of this study was to investigate how the activator type affects the performance of X-ray scintillators. To this aim the behavior of scintillator materials was modeled under X-ray excitation conditions, similar to those used in imaging techniques. The model describes the light emission efficiency, the spectral compatibility with optical detectors (films, photodiodes, and photocathodes), ...
