Total internal reflection fluorescence.
Total internal reflection fluorescence (TIRF) is an optical effect particularly well-suited to the study of molecular and cellular phenomena at liquid/solid interfaces. Such interfaces are central to a wide range of biochemical and biophysical processes: binding to and triggering of cells by hormones, neurotransmitters, and antigens; blood coagulation at foreign surfaces; electron transport in ...
متن کاملGuiding Light by and beyond the Total Internal Reflection Mechanism
Photonics plays an important role in modern technologies, e.g. in telecommunications and sensing systems. Waveguiding structures with microand nano-meter scale features are the basic building blocks of photonic circuits. Large varieties of structures have been used by scientists and engineers. These range from the conventional planar and channel waveguides, which work on the basis of the total-...
متن کاملImaging synaptosomal calcium concentration microdomains and vesicle fusion by using total internal reflection fluorescent microscopy.
Transmitter release at chemical synapses is triggered by high calcium concentration microprofiles at the presynaptic cytosol. Such microprofiles, generated by the opening of voltage-dependent calcium channels at the presynaptic plasma membrane, have been defined as calcium concentration microdomains. Using total internal reflection fluorescent microscopy in conjunction with calcium and vesicula...
متن کاملTotal internal reflection Raman spectroscopy.
Total internal reflection (TIR) Raman spectroscopy is an experimentally straightforward, surface-sensitive technique for obtaining chemically specific spectroscopic information from a region within approximately 100-200 nm of a surface. While TIR Raman spectroscopy has long been overshadowed by surface-enhanced Raman scattering, with modern instrumentation TIR Raman spectra can be acquired from...
متن کاملAngle-invariant imaging using a total internal reflection virtual aperture.
Conventional lens stops, implemented with an absorptive physical aperture, have an angle-dependent projection that introduces field dependent loss and reduces diffraction-limited resolution. Retro-telephoto lenses obtain uniform response using aberration vignetting, but this results in low wide-angle resolution and significant lens volume. However, an angle-independent "virtual" aperture can be...
