The semiconductor nanocrystal core can be composed of a semiconductor material (including binary, ternary and quaternary mixtures thereof), from: Groups II-VI of the periodic table, including ZnS, ZnSe, ZnTe, CdS, CdSe, CdTe, HgS, HgSe, HgTe, MgTe; Groups III-V, including GaN, GaP, GaAs...
Compared to the common transition metals, very little is known about the chemistry of technetium. Technetium belongs to Group VII-B of the Periodic Table; its chemistry bears a superficial resemblance to manganese but tends to be more similar to the higher member of the Group, rhenium. Technetiu...
Compounds are provided for use in assays of organic compounds, where organic compounds of biological interest are determined at extremely low concentrations by combining in a medium, the composition to be determined, hereinafter referred to as ligand, a high molecular weight material of at least 10...
Generally, X+mis hydrogen or a monovalent or divalent cation from Groups IA or IIA of the Periodic Table, such as alkali metal ions (for example, sodium, potassium and rubidium) and alkaline earth metal ions (for example, magnesium, calcium and strontium). Alkali metal ions such as sodium ...
is a function of the size of the bleached area and the rate of mobility of the fluorophores or labeled molecules. The periodic pattern of photobleaching technique invented by Smith and McConnell (1978) supra., makes FRAP simpler in theory and in practice. The periodic pattern can be obtained ...
