High resolution spectral self-interference fluorescence microscopy
We present a new method of fluorescence imaging, which yields nm-scale axial height determination and ~15 nm axial resolution. The method uses the unique spectral signature of the fluorescent emission intensity well above a reflecting surface to determine vertical position unambiguously. We have demonstrated axial height determination with nm sensitivity by resolving the height difference of fl...
متن کاملSpatial extensions to self - modeling curve resolution
Through recent developments in data acquisition procedures, large amounts of spatially resolved hyperspectral data have become available. However, the development of adequate data analysis methods which exploit the intrinsic spatial information lags behind. We propose a self-modeling curve resolution (SMCR) algorithm which takes spatial relationships into account. This is accomplished by enforc...
متن کاملMajor-to-ultratrace elements in bone-marrow fluid as determined by ICP-AES and ICP-MS.
The major-to-ultratrace elements in human bone-marrow fluid were determined by ICP-AES (inductively coupled plasma atomic emission spectrometry), and ICP-MS (inductively coupled plasma mass spectrometry). The bone-marrow fluid sample was centrifuged prior to acid digestion to exclude the bone piece from bone marrow, and then digested with nitric acid. As a result, 20 elements could be determine...
متن کاملApplication of two-dimensional correlation spectroscopy to chemometrics: self-modeling curve resolution analysis of spectral data sets.
This paper demonstrates the use of two-dimensional (2D) correlation spectroscopy in conjunction with alternating least squares (ALS) based self-modeling curve resolution (SMCR) analysis of spectral data sets. This iterative regression technique utilizes the non-negativity constraints for spectral intensity and concentration. ALS-based SMCR analysis assisted with 2D correlation was applied to Fo...
متن کاملSpectral self-interference fluorescence microscopy
Spontaneous emission of fluorophores located close to a reflecting surface is modified by the interference between direct and reflected waves. The spectral patterns of fluorescent emission near reflecting surfaces can be precisely described with a classical model that considers the relative intensity and polarization state of direct and reflected waves depending on dipole orientation. An algori...
