FLUORINATED RESPONSIVE LANTHANIDE COMPLEXES FOR MAGNETIC RESONANCE
A series of novel fluorinated lanthanide complexes has been synthesised for use as responsive probes for 19F MRS and MRI. The careful positioning of the CF3 group within 6.5 Å from the metal ion caused the fluorine longitudinal and transversal relaxation rates to be strongly enhanced. This allows …

Direct detection of homocysteine and syntheses of lanthanide complexes as biosensors
At elevated levels, homocysteine (Hcy) is a risk factor for cardiovascular diseases and Alzheimer’s disease. It’s also implicated in a number of other diseases such as neural tube defects, pregnancy complications, and renal failures. The monitoring of Hcy levels in plasma is of current concern. To …

Lanthanide complexes as fluorescent indicators for neutral sugars and cancer biomarkers
Simple water soluble lanthanum and europium complexes are effective at detecting neutral sugars as well as glyco- and phospholipids. In solutions at physiologically relevant pH the fluorescent lanthanum complex binds neutral sugars with apparent binding constants comparable to those of arylboronic …

Singlet oxygen generating luminescent lanthanide complexes with naphthalimide-based and oligothiophene-based sensitizers
Luminescent lanthanide (LnIII) complexes that also generate singlet oxygen (1O2) are of interest to medical, biological, and analytical fields, as they can provide cytotoxicity and luminescence using light excitation. Because of the interest in these compounds, systematic studies were used to help …
