In particular, upon excitation around nm, the fluorescence ratio of the protein bound and the free coenzyme NADH depends on the state of malignancy.

Slight differences are also observed in Raman spectra of these cell lines, in particular at wave numbers around cm While larger numbers of fluorescence and Raman spectra are evaluated by the method of multivariate data analysis, additional information is obtained from spectral images and fluorescence lifetime images FLIM.

Proceedings Article 25 November Microfluidic system for single cell sorting with optical tweezers. A microfluidic system was developed and combined with optical tweezers for single cell sorting.

Selected cells are trapped and moved in perpendicular direction to the main flow for recovery in special reservoirs and further evaluation e.

In addition, maximum light doses and exposure times for maintaining cell viability were determined. Fluorescence imaging of membrane dynamics in living cells.

Methods of wide-field fluorescence microscopy for measuring membrane dynamics of living cells are described, including spectral imaging as well as anisotropy imaging of the membrane marker 6-dodecanoyldimethylamino naphthalene laurdan.

Plasma membranes are selected by illumination with an evanescent electromagnetic field and distinguished from intracellular membranes assessed by whole-cell illumination.

While fluorescence spectra of laurdan appeared red-shifted with decreasing membrane stiffness, fluorescence anisotropy and rotational correlation times were reduced with increasing membrane fluidity.

Membrane stiffness was found to increase with decreasing temperature and increasing amounts of cholesterol and was always higher for the plasma membrane than for intracellular membranes.

These effects may have some clinical relevance in the research of drug resistance or cell aging. Proceedings Article 8 July A membrane-associated FRET sensor for detection of apoptosis.

Upon apoptosis a caspase sensitive amino acid peptide linker DEVD between these proteins is cleaved, and pronounced changes of fluorescence spectra and lifetimes are observed.

Membrane selective detection of fluorescent proteins in cultivated HeLa cervix carcinoma cells is achieved by total internal reflection fluorescence microscopy TIRFM with high sensitivity and resolution.

Proceedings Article 1 July Dose limited fluorescence microscopy of living cells. Light dose plays an important role for maintaining viability in optical microscopy of living cells.

Therefore, a colony forming assay was established, and non-phototoxic light doses were determined for glioblastoma cells.

Microscopic methods were adapted to those light doses, and often wide field methods appeared to be more appropriate than laser scanning methods.

Förster resonance energy transfer-based total internal reflection fluorescence reader for apoptosis. A fluorescence reader for the detection of Förster resonance energy transfer FRET on surfaces of living cells is described.

The method is based on multiple total internal reflections TIR of an incident laser beam within a glass slide, such that individual samples on top of the glass slide are illuminated simultaneously by an evanescent electromagnetic field.

Enhanced cyan fluorescent protein ECFP anchored to the inner leaflet of the plasma membrane is optically excited and transfers its excitation energy via the peptide linker Asp-Glu-Val-Asp DEVD to an enhanced yellow fluorescent protein.

Upon apoptosis, DEVD is cleaved, and energy transfer is disrupted, as proven by an increase of fluorescence intensity as well as of fluorescence lifetime of the donor ECFP.

Due to selective excitation of membrane-associated fluorophores, intracellular fluorescence and background luminescence from the surrounding medium are eliminated.

Therefore, this test system appears to be a sensitive device for the detection of apoptosis and more generally for drug screening or in vitro diagnosis on a nanometer scale.

Proceedings Article 18 February Dose limited fluorescence microscopy of 5-aminolevulinic acid induced protoporphyrin IX in living cells. Schneckenburger , P.

Weber , M. Wagner , S. Schickinger , T. Bruns , W. Intracellular accumulation and location of photosensitizers, e. Therefore, prior to microscopic experiments non-phototoxic light doses were determined, and experimental conditions of laser scanning LSM and wide field microscopy were adapted to these doses.

Wide field images appeared more brilliant than LSM images, thus demonstrating some advantage of simultaneous over sequential detection.

In addition, human glioblastoma cells appeared less sensitive towards illumination by an evanescent electromagnetic field than towards epi-illumination, since only their plasma membranes and adjacent parts were exposed to light.

Proceedings Article 12 February Fluorescence and polarization imaging of membrane dynamics in living cells.

Wagner , P. Weber , T. Strauss , H. Methods of wide field fluorescence microscopy for measuring membrane dynamics in living cells are described.

These methods are based on laser pulse excitation of the membrane marker 6-dodecanoyldimethylamino naphthalene laurdan whose emission spectra, fluorescence decay kinetics and anisotropies are sensitive to membrane stiffness and fluidity.

Plasma membranes are selected by illumination with an evanescent electromagnetic field and distinguished from intracellular membranes assessed by whole cell illumination.

While fluorescence spectra of laurdan appeared red-shifted with decreasing membrane stiffness, fluorescence anisotropy and rotational relaxation times were reduced with increasing membrane fluidity.

Membrane stiffness was found to increase with decreasing temperature and increasing amounts of cholesterol.

In addition, membrane stiffness of the plasma membrane was always higher than that of intracellular membranes. These effects may have some influence on pathogenesis of certain diseases, uptake of pharmaceutical agents or cell aging.

Axial tomography in live cell laser microscopy. Single cell microscopy in a three-dimensional 3-D environment is reported. Cells are grown in an agarose culture gel, located within microcapillaries and observed from different sides after adaptation of an innovative device for sample rotation.

Thus, z-stacks can be recorded by confocal microscopy in different directions and used for illustration in 3-D. This gives additional information, since cells or organelles that appear superimposed in one direction, may be well resolved in another one.

The method is tested and validated with single cells expressing a membrane or a mitochondrially associated green fluorescent protein, or cells accumulating fluorescent quantum dots.

This paper discusses that upon cell rotation an enhanced optical resolution in lateral direction compared to axial direction can be utilized to obtain an improved effective 3-D resolution, which represents an important step toward super-resolution microscopy of living cells.

Proceedings Article 15 July Low light exposure in light sheet fluorescence microscopy is combined with the detection of spectral changes and prolonged fluorescence lifetimes of the donor ECFP upon apoptosis.

In view of future label-free detection preliminary experiments of light scattering microscopy with high angular resolution are reported which may give additional information on morphological changes.

Nanosecond ratio imaging of redox states in tumor cell spheroids using light sheet-based fluorescence microscopy. A new concept of three-dimensional imaging of tumor cell spheroids by light sheet-based fluorescence microscopy and nanosecond ratio imaging is described.

Due to its low light dose and alternative excitation by two laser wavelengths and nm , this method maintains cell viability and permits recording of real-time kinetics.

A genetically encoded sensor permits measurement of the redox state of glutathione and visualization of the impact of oxygen radicals. The pharmaceutically relevant system is tested upon addition of an oxidizing agent H 2 O 2 , as well as upon addition of the apoptosis-inducing agent staurosporine.

Proceedings Article 18 June Visualizing a cytostatic drug and probing apoptosis of cancer cells. The uptake and intracellular distribution of the cytostatic drug doxorubicin is visualized in 2D and 3D systems of human breast cancer cells and fibroblasts by fluorescence microscopy and spectroscopy.

Fluorescence lifetime imaging FLIM and scattering experiments with high angular resolution are suggested to probe apoptotic reactions.

A light scattering microscope as well as a light sheet module for 3D fluorescence microscopy have been developed and are used for this purpose. Tumor cell differentiation by label-free fluorescence microscopy.

Autofluorescence spectra, images, and decay kinetics of UMG glioblastoma cells prior and subsequent to activation of tumor suppressor genes are compared.

While phase contrast images and fluorescence intensity patterns of tumor control cells and less malignant cells are similar, differences can be deduced from autofluorescence spectra and decay kinetics.

In particular, upon near UV excitation, the fluorescence ratio of the free and protein-bound coenzyme nicotinamid adenine dinucleotide depends on the state of malignancy and reflects different cytoplasmic including lysosomal and mitochondrial contributions.

While larger numbers of fluorescence spectra are evaluated by principal component analysis, a multivariate data analysis method, additional information on cell metabolism is obtained from spectral imaging and fluorescence lifetime imaging microscopy.

Proceedings Article 15 June Strauss , Rainer Wittig , Herbert Schneckenburger. A novel setup for fluorescence imaging of 3-dimensional cell cultures is described.

The method is based on structured illumination by various light sources and detection of images in individual cellular planes. Proceedings Article 11 February Tumor cell differentiation by marker free fluorescence microscopy.

Autofluorescence and Raman spectra, images and decay kinetics of UMG glioblastoma cells prior and after activation of tumor suppressor genes are compared.

While phase contrast images and fluorescence patterns of the tumor control cells and the less malignant cells are similar, differences can be deduced from autofluorescence spectra and decay times.
