What is time resolved fluorescence spectroscopy?
Time-resolved fluorescence spectroscopy is a spectroscopy technique used to monitor interactions between molecules and motions that occur in the short periods. The ability to measure changes in the picosecond or nanosecond time range makes it a useful technique in biomolecular structure analysis and dynamics.
What is time resolved microscopy?
`Time resolved imaging microscopy’ is a relatively new technique whereby fast kinetic and luminescence decay parameters (decay times and the corresponding time or phase resolved amplitudes) are directly and simultaneously measured throughout an image, pixel by pixel, in an optical microscope.
What is time resolved measurement?
Time-resolved absorption spectroscopy relies on our ability to resolve two physical actions in real time. The shorter the detection time, the better the resolution. The impact of the probe pulse on the sample is recorded and analyzed with wavelength/ time to study the dynamics of the excited state.
What is time-resolved NMR?
NMR spectroscopy is a versatile tool for studying time-dependent processes: chemical reactions, phase transitions or macromolecular structure changes. However, time-resolved NMR is usually based on the simplest among available techniques – one-dimensional spectra serving as “snapshots” of the studied process.
What is time-resolved photoluminescence?
Time-resolved photoluminescence spectroscopy (TRPL) is an extension to normal spectroscopy in which a short laser pulse is used for excitation, and a fast detector is used to determine the emission of a material as a function of time after excitation.
Which microscope has the highest resolution?
The microscope that can achieve the highest magnification and greatest resolution is the electron microscope, which is an optical instrument that is designed to enable us to see microscopic details down to the atomic scale (check also atom microscopy).
How does super resolution fluorescence imaging overcome the diffraction limit?
With sufficiently strong excitation, the fluorescence emission from a fluorophore will saturate. Saturated SIM (SSIM) utilizes this phenomenon to create sharp dark regions where the excitation pattern has zero intensity, providing image resolution significantly beyond the diffraction limit (Figure 2B).
What is transient absorption?
Transient absorption (TA) spectroscopy, also known as flash photolysis, is a pump-probe spectroscopic technique utilised to measure the photogenerated excited state absorption energies and associated lifetimes of molecules, materials, and devices.
