Fluorescence spectroscopy is a powerful tool to investigate the photochemistry of biological systems. In this application note the influence of temperature on the photochemistry of perennial leaves is investigated by measuring the fluorescence quantum yield over a temperature range of 77 K to 300 K using the FLS1000 equipped with the Cryosphere accessory.

Persistent luminescence, commonly called afterglow, is long-lasting visible emission over several hours after ultraviolet excitation. It has many applications; ranging from glow-in-the-dark signage to in-vivo imaging for disease diagnosis and treatment. In this application note, the persistent luminescence kinetics of a doped strontium aluminate phosphor are characterised using the FLS1000 Photoluminescence spectrometer

Molecular beacon probes are a sequence of nucleotides (the building blocks of DNA and RNA) that can be used to fluorescently detect the presence of a specific sequence of DNA or RNA. With real-world examples as PCR quantification, in vivo RNA detection, pathogen detection and viral load quantification. The use of molecular beacons, coupled with a sensitive spectrofluorometer facilitates the measurement of extremely low concentrations of DNA or RNA. In this application note, nanomolar concentrations of cDNA were quantified using a molecular beacon while controlling the temperature of incubation and measuring the sample emission with an Edinburgh Instruments FS5 Spectrofluorometer.
