“…Then, we realized on the same crystal electroless contacts using the standard procedure (5% gold chloride water solution, dark conditions, and washing with water after 1 minute reaction). This procedure has been described in many papers and it ensures the formation of contacts with good spectroscopic performances, even if the mechanical adhesion is not completely satisfactory, and in any case comparable to other deposition technologies, such as sputtering or thermal evaporation . The dimensions and the shape of the contacts were the same (8×5 mm 2 , with 0.5 mm gap between sample edge and contact).…”

Recently some of the authors have proposed a new technique to deposit contacts on CdZnTe detectors that combines the standard electroless procedure and the scanning pipette technique. In this work it is shown that by using a 15 micron inner diameter alumina pipette it is possible to deposit gold dots, pixels and micro-stripes without using the standard photolithographic process. Moreover, it is shown that the performances in terms of charge collection efficiency and energy resolution of detectors prepared with the scanning pipette technique are similar to the ones of detectors prepared with the standard electroless procedure.

“…The authors commented on the growth of these lms with sputtering conditions. Zheng et al 411 reported the deposition of double nanometric layers of Ru/Au, Ru/Pd, and Pd/Au onto CdZnTe by the electrodeless method. The deposited layers were analysed by TXRF and RBS to determine the thickness, the depth proles and the composition of the layers.…”

This work presents the first application of total-reflection X-ray fluorescence (TXRF) spectrometry, a new and powerful alternative analytical method, to evaluation of the bioaccumulation kinetics of gold nanorods (GNRs) in various tissues upon intravenous administration in mice. The analytical parameters for developed methodology by TXRF were evaluated by means of the parallel analysis of bovine liver certified reference material samples (BCR-185R) doped with 10 μg/g gold. The average values (n = 5) achieved for gold measurements in lyophilized tissue weight were as follows: recovery 99.7%, expanded uncertainty (k = 2) 7%, repeatability 1.7%, detection limit 112 ng/g, and quantification limit 370 ng/g. The GNR bioaccumulation kinetics was analyzed in several vital mammalian organs such as liver, spleen, brain, and lung at different times. Additionally, urine samples were analyzed to study the kinetics of elimination of the GNRs by this excretion route. The main achievement was clearly differentiating two kinds of behaviors. GNRs were quickly bioaccumulated by highly vascular filtration organs such as liver and spleen, while GNRs do not show a bioaccumulation rates in brain and lung for the period of time investigated. In parallel, urine also shows a lack of GNR accumulation. TXRF has proven to be a powerful, versatile, and precise analytical technique for the evaluation of GNRs content in biological systems and, in a more general way, for any kind of metallic nanoparticles.
