Sample autofluorescence (fluorescence of inherent components of tissue and fixative-induced
fluorescence) is a significant problem in direct imaging of molecular processes in …

Mounting evidence indicates that zinc has multiple roles in cell biology, viz. as a part of
metalloenzyme catalytic sites, as a structural component of gene regulatory proteins, and (like …

We report real-time, in situ determination of free copper ion at picomolar levels in seawater
using a fluorescence-based fiber optic biosensor. The sensor transducer is a protein molecule…

We describe the construction and performance of a variable-frequency phase-modulation
fluorometer. This instrument, which provides modulation frequencies from 1 to 200 MHz, was …

The fluorescence lifetimes of most red emitting organic probes are under 4 nanoseconds,
which is a limiting factor in studying interactions and conformational dynamics of …

CONCLUSION We have therefore shown that very substantial differ-ences exist in the
distribution of 2H within ethanol mol-ecules according to their origin. We dispose now of new and …

We describe multiphoton excitation of the lanthanides europium (Eu 3+ ) and terbium (Tb 3+
) when these ions are complexed with nucleic acids, proteins, and fluorescent chelators. In …

Because of their high affinity and selectivity, metalloproteins can be used as transducers in
novel sensors, ie, biosensors, for the determination of trace levels of metal ions in solution. …

We demonstrate here that electrical stimulation of organotypic cultures of rat hippocampus
results in the prompt release of significant amounts of Zn(II) by a fluorescence microscopic …
