Dynamic Light Scattering Instrument with a Time Interval Digitizer

A new instrument for time-resolved static and dynamic light-scattering experiments in turbid media.

We present a new 3D cross-correlation instrument that not only allows for static and dynamic scattering experiments with turbid samples but measures at four angles simultaneously. It thus extends the application of cross-correlation light scattering to time-resolved studies where we can, for example, efficiently investigate the temporal evolution of aggregating or phase separating turbid disper...

Entrapment–D-(+)-Glucose Water Nanodroplet: Synthesis and Dynamic Light Scattering

In the present research, the D-(+)-Glucose–confined water nanodroplets with mean size in the range of 6-11 nm were synthesized at D-(+)-Glucose different concentrations by AOT reverse micelles (RMs) method as a function of mass fraction of droplet (MFD) at the constant water-to-surfactant molar ratio ( W=40). The dynamic light scattering of the nano-sized water droplets containing the D-(+)-Glu...

Microscope-based static light-scattering instrument.

We describe a new design for a microscope-based static light-scattering instrument that provides simultaneous high-resolution images and static light-scattering data. By correlating real space images with scattering patterns, we can interpret measurements from heterogeneous samples, which we illustrate by using biological tissue.

Dynamic Light Scattering

A HeNe laser beam incident on a sample of micron-sized spheres suspended in water scatters into a random pattern of spots of varying size, shape, and intensity. The pattern results from the coherent superposition of the outgoing waves scattered from the spheres. Because the spheres are in constant Brownian motion, the pattern randomly changes in time. A photodetector is placed in the pattern an...
