The energy transfer donor terbium chelate on the RLC (A) and on the Fab of a monoclonal antibody to the rod (B) showed four sharp peaks at 490, 547, 590, and 623 nm without emissions between them.
With the acceptor-labeled F-actin binding to the donor-labeled papain S1, the sensitized emission at 568 nm and the donor quenching at 547 nm demonstrated that the resonance energy transfer was occurring between S1 RLC and actin Cys-374.

Fluorides of yttrium, terbium and lutecium, if administered into stomach, result in specific intoxication (fluorosis).
According to short-term tests of cytotoxicity, the foreseeable fibrogenic danger for ytterbium fluoride is moderate, for fluorides of yttrium, terbium and lutecium is mild.
The authors recommend to control the level of yttrium, terbium and lutecium fluorides in the air of workplace through the MACs for the fluorides at 2.5 mg/cu m (maximal single concentration) and 0.5 mg/cu m (average shift concentration), the level of ytterbium fluoride as moderate fibrogenic dust at 6 mg/cu m.

Many binary and complex oxides are available for deposition onto particulates or reticulated metallic or ceramic bodies, where specific properties such as catalytic activity, surface modification of dielectric/conductivity characteristics, optical characteristics, and the requirement for hydrophobic coatings is required.
In general, fluorides are employed for their chemical inertness, and optical qualities, through thin film interference effects they impart to suitable substrates.
Most applicable fluorides have very low solubilities in aqueous systems, and are deposited via specialized and proprietary methods.
