Dynamic light scattering studies of ribonuclease
Biophysical Chemistry, 1980Dynamic light scattering has been used to measure the translational diffusion coefficients of bovine pancreatic ribonuclease A as functions of temperature and concentration in the presence of 1 M Guanidine-HCl. Data was collected throughout a temperature range including the folding-unfolding transitions.

Resonance enhanced dynamic light scattering
Review of Scientific Instruments, 2011We present a novel light scattering setup that enables probing of dynamics near solid surfaces. An evanescent wave generated by a surface plasmon resonance in a metal layer is the incident light field in the dynamic light scattering experiment.

Dynamic Light Scattering Of Biopolymers And Biocolloid
CRC Critical Reviews in Biochemistry, 1977Widespread applications of dynamic light scattering techniques to the study of macromolecular Brownian motion have yielded not only a valuable store of factual information concerning solution conformations and conformational changes, but have also provided an important window through which to view the dynamics of internal modes of motion.

Dynamic light scattering in subdiffusive regimes
Applied Optics, 2001For describing the fluctuating signal scattered from a multiple-scattering system, diffusive-wave spectroscopy makes use of a diffusion model that provides the path-length distribution of scattered waves for a specific geometry. Using the recently introduced optical path-length spectroscopy, we show that the diffusion model fails to describe wave ...

Dynamic Light Scattering of Diabetic Vitreopathy
Diabetes Technology & Therapeutics, 1999Diabetes induces pathology throughout the body via nonenzymatic glycation of proteins. Vitreous, which is replete with type II collagen, undergoes significant changes in diabetes. The resultant diabetic vitreopathy plays an important role in diabetic retinopathy.

Analysis of the Dynamics of Cryoaggregation by Light-Scattering Spectrometry
Clinical Chemistry and Laboratory Medicine, 2003Cryoglobulins are proteins that precipitate at temperatures below 37 degrees C. Cold-induced precipitation of proteins may occur in vivo secondary to several important diseases, and lead to pathological manifestations involving different organs. Cryoprecipitation may be observed in vitro by exposing serum samples, supposed to contain cryoglobulins, to ...

Dynamic light scattering methods for biorhelogy
Biorheology, 1987Several noninvasive light scattering techniques are reviewed that can be utilized in rheological studies of mucus and other soft biological matrices. Included are quasielastic light scattering techniques to determine the compressibility moduli of polymer lattices, resonance methods that can be used to measure the shear modulus of weak gels, assays that

Homodyne Optical Fiber Dynamic Light Scattering
Photon Correlation and Scattering, 2000Optical fiber homodyne dynamic light scattering employs both the advantage of a sensitivity improvement over the standard self-beating technique and the inherent self-aligning simplicity of the optics. Ultralow concentrations of approximately nanometer-sized particles become accessible by dynamic light-scattering techniques.

Dynamic Light Scattering (DLS)
2019Particles dispersed in a solution are constantly moving in Brownian motion. Since this Brownian motion depends on the velocity of the particle size, the size can be estimated by observing the fluctuation corresponding to this velocity. By obtaining the autocorrelation function of the observed fluctuation, the particle size and distribution can be ...
