We present the technical integration of state-of-the-art picosecond diode laser sources and data acquisition electronics in conventional laser scanning microscopes. This procedure offers users of laser scanning microscopes an easy upgrade path towards time-resolved measurements. Our setup uses picosecond diode lasers from 375 to 800 nm for excitation which are coupled to the microscope via a single mode fiber. The corresponding emission is guided to a fibre coupled photon counting detector, such as Photomultiplier Tubes (PMT) or Single Photon Avalanche Diodes (SPAD). This combines the outstanding sensitivity of photon counting detectors with the ease of use of diode laser sources, to allow time-resolved measurements of fluorescence decays with resolutions down to picoseconds. The synchronization signals from the laser scanning microscope are fed into the data stream recorded by the TimeHarp 200 TCSPC system, via the unique Time-Tagged Time-Resolved (TTTR) data acquisition mode. In this TTTR data acquisition mode each photon is recorded individually with its specific parameters as detector channel, picosecond timing, global arrival time and, in this special application, up to three additional markers. These markers, in combination with the global arrival time, allow the system software to reconstruct the complete image and subsequently create the full fluorescence lifetime image (FLIM). The multi-parameter data acquisition scheme of the TimeHarp 200 electronics not only records each parameter individually, but offers in addition the opportunity to analyse the parameter dependencies in a multitude of different ways. This method allows for example to calculate the fluorescence fluctuation correlation function (FCS) on any single spot of interest but also to reconstruct the fluorescence decay of each image pixel and detector channel for advanced Forster Resonance Energy Transfer (FRET) analysis. In this paper, we present some selected results acquired with standard laser scanning microscopes upgraded towards temporal resolution.

We present the technical integration of state-of-the-art picosecond diode laser sources and data acquisition electronics in conventional laser scanning microscopes. This offers users of laser scanning microscopes an easy upgrade path towards time-resolved measurements. Our setup uses picosecond diode lasers from 375 nm, 405 nm, 440 nm and 470 nm for fluorescence excitation which are coupled in through a sole single mode fiber. The detected signal is guided to a photon counting detector, such as Photomultiplier Tubes (PMT) or Single Photon Avalanche Diodes (SPAD). This combines the outstanding sensitivity of photon counting detectors with the ease of use of diode laser sources, to allow time-resolved measurements of fluorescence decays with resolutions down to picoseconds. The synchronization signals from the laser scanning microscope are fed into the data stream recorded by the TimeHarp 200 TCSPC5,7 system, via the unique Time-Tagged Time-Resolved (TTTR)6 data acquisition mode. In this TTTR data acquisition mode each photon is recorded individually with its specific parameters as detector channel, picosecond timing, global arrival time and, in this special application, up to three additional markers. These markers, in combination with the global arrival time, allow the system software to reconstruct the complete image and subsequently fit the full fluorescence lifetime image. The multi-parameter data acquisition scheme of the TimeHarp 200 electronics not only records each parameter individually, but offers in addition the opportunity to analyse the parameter dependencies in a multitude of different ways. This method allows not only to calculate the fluorescence fluctuation correlation function (FCS) on any single spot of interest but also to reconstruct the fluorescence decay of each image pixel and detector channel for the purpose of Fluorescence Lifetime Imaging (FLIM) or advanced Fluorescence Resonance Energy Transfer (FRET) analysis. We present here some selected results acquired with standard laser scanning microscopes upgraded for the time-correlated single photon counting technique.

Time-resolved microspectrofluorometry and fluorescence lifetime imaging of photosensitizers using picosecond pulsed diode lasers in laser scanning microscopes

This work describes the time-resolved fluorescence characteristics of two different photosensitizers in single cells, in detail mTHPC and 5-ALA induced PPIX, which are currently clinically used in photodynamic therapy. The fluorescence lifetime of the drugs was determined in the cells from time-gated spectra as well as single photon counting, using a picosecond pulsed diode laser for fluorescence excitation. The diode laser, which emits pulses at 398 nm with 70 ps full width at half maximum duration, was coupled to a confocal laser scanning microscope. For time-resolved spectroscopy a setup consisting of a Czerny Turner spectrometer and a MCP-gated and -intensified CCD camera was used. Time-gated spectra within the cells were acquired by placing the laser beam in ‘‘spot scan’’ mode. In addition, a time-correlated single photon counting module was used to determine the fluorescence lifetime from single spots and to record lifetime images. The fluorescence lifetime of mTHPC decreased from 7.5 to 5.5 ns during incubation from 1 to 6 h. This decrease was probably attributed to enhanced formation of aggregates during incubation. Fluorescence lifetime imaging showed that longer lifetimes were correlated with accumulation in the cytoplasm in the neighborhood of the cell nucleus, whereas shorter lifetimes were found in the outer cytoplasm. For cells that were incubated with 5-ALA, a fluorescence lifetime of 7.4 ns was found for PPIX; a shorter lifetime at 3.6 ns was probably attributed to photoproducts and aggregates of PPIX. In contrast from fluorescence intensity images alone, different fluorescence species could not be distinguished. However, in the lifetime image a structured fluorescence distribution in the cytoplasm was correlated with the longer lifetime and probably coincides with mitochondria. In conclusion, picosecond diode lasers coupled to a laser scanning microscope equipped with appropriate detection units allows time-resolved spectroscopy and lifetime imaging with high spatial resolution and provides numerous possibilities in cellular and pharmaceutical research.
