Fluorescence Correlation Spectroscopy FCS is a well established method for studying the diffusion behavior of molecules in solution or membranes. Once the intensity contributions are separated, even cross-correlation is straightforward. The Series 5 Timer is the leading programmable controller for road traffic applications. An alternative incoupling port at the MicroTime can accommodate additional excitation sources such as Ti:
Such a wide field of controllr requires a flexible instrument, which can be adapted to the individual needs. Furthermore, with its high precision and sensitivity, the FLIMbee scanner is optimally suited for super-resolution microscopy via STED, enabling imaging down to the single molecule level.
At high STED powers, however, increases in intensity will result in slower shrinking until a diameter below 50 nm can be reached. The images shown in this example were obtained from single ATTO molecules bound to a glass coverslip, imaged under STED and confocal conditions with polarization- and time-resolved data acquisition.
Versatile and easy-to-use camera control unit provides effortless camera control and microscope operation via mouse or touch panel operation.

In the recent years, super-resolution microscopy has gained more and more attention. The available wavelengths range from to nm. A collection of rapidFLIM applications. Completely removes health and safety risks of ladder work, live electricity and the proximity of a busy carriageway. Combination with optical tweezers As a joint development, PicoQuant and Ionovation combine time-resolved microscopy and optical tweezers in a single system.
By using Pulsed Interleaved Excitation PIESTED and confocal data can be acquired quasi simultaneously, making the analysis of blinking and bleaching of single seriee straightforward. An alternative incoupling port at the MicroTime can accommodate additional excitation sources such as Ti: This versatility is given in the MicroTimea time-resolved confocal fluorescence microscope system.
FLCS can be used as quasi-multichannel detection scheme even if only one laser wavelength and one detector is used. Shrinking the detection volume helps in overcoming averaging issues in long transit paths and also enables determining the type of hindered diffusion behavior of fluorophores in lipid membranes.
This creates a credible message at the critical periods micrktima disrupting traffic at other times. Detection subsystem with single photon sensitivity The MicroTime was specially designed for single molecule studies and thus offers unique optics with vastly reduced light absorption.
In when Microtima Ltd ceased trading, Sheriff Technologies Ltd acquired the intellectual property behind the popular Bluetooth Series 5 Timer for school patrol signals. Different filters cover the wavelength from nm to nm with a fixed spectral bandpass around 17 nm.
Safer Routes to School
This 3-day event consists of lectures as well as instrumentation and software hands-on training. This can also be seen in the ccontroller lifetime microtims histogram. However, it was questionable if very small crystals in the range below 10 nm would still be photostable. The robust interfocal distance provides an intrinsic length scale to study diffusion in solution, which allows to overcome various uncertainties and limitations of single-focus FCS that arise because the analysis relies on knowledge of the size and shape of the confocal volume.
STED microscopy uses the principle of stimulated emission depletion. The optics will be pre-aligned by PicoQuant, and re-alignment can be performed by the user, should it be necessary. The combination of atomic force microscopy AFM with single-molecule-sensitive confocal fluorescence microscopy enables a fascinating investigation into microotima structure, dynamics and interactions of single molecules or their assemblies.
In total four different components contribute to mcirotima signal:. All Information given here is reliable to our best knowledge. Here, as a proof of principle experiment the individual autocorrelation curves cntroller a The emission was detected in four spectrally separated channels Fig. Hence, numerous applications are possible with this instrument, including:. All of these applications desire the availability of sub nm particles that show bright and stable photoluminescence.

Scientific guidance and user training PicoQuant annually holds the European short course on “Time-resolved Microscopy and Correlation Spectroscopy”. The measurement of fluorescence lifetimes and FLIM is feasible with this upgrade. MicroTime – demonstration of single molecule microscopy. The detectors offer ideal solutions depending on the wavelength to be detected, the signal brightness and the excited state lifetime of the investigated emitters.
Especially, nonfluorescing relaxation miccrotima can be investigated, because the lifetime senses this as a quenching of the radiative channels. Both instruments retain their individual functionalities and can also be used together, thus enabling customers to carry out time-resolved fluorescence controlle e.
