Dynamic light scattering (DLS) is used to monitor the formation of truncated ACE2 peptide-conjugated gold nanoparticles and determine their binding constants kinetics SARS-CoV-2 RBD.

The present study aims at study on combined effect of zinc oxide nanoparticles (ZnO) with common agricultural fungicides. Nanoparticles were synthesized using chemical reduction process and characterized by UV-Visible spectroscopy, X-ray diffraction (XRD), Dynamic Light Scattering (DLS) and Transmission Electron Microscopy (TEM). Synthesized nanoparticles were observed to be in size range of 12...

The nanostructured anatase TiO2 with high thermal stability was prepared by polymeric sol-gel method without any additives. The particle size distribution of polymeric titania sol was determined by dynamic light scattering (DLS). Then properties of obtained titania were investigated by TG-DTA, XRD, FESEM and TEM. Also, the decolorization capability of resultant anatase was evaluated using methy...

We examined the synthesis and characterization of polymer micelle using polymerizable cationic gemini surfactant (surfmer). Here, cationic gemini surfmer (GS) was newly synthesized and characterized. Also, a “monomer”-type surfmer (MS) was synthesized and characterized for comparison. The equilibrium properties in water and in the presence of 0.1 M NaBr were investigated by means of surface ten...

the use of biogenic selenium nanoparticles for various purposes is going to be an issue of considerable importance; thus, appropriate simple methods should be developed and tested for the synthesis and recovery of these nanoparticles. in this study, a fungus was isolated from a soil sample, identified as aspergillus terreus and used for extracellular synthesis of selenium nanoparticles (se nps)...

Silicon-based mesoporous nanoparticles have been extensively studied to meet the challenges in the drug delivery. Functionality of these nanoparticles depends on their properties which are often changing as a function of particle size and surrounding medium. Widely used characterization methods, dynamic light scattering (DLS), and transmission electron microscope (TEM) have both their weaknesse...

In this chapter we describe a recent development in dynamic light scattering (DLS), which may ultimately have a significant impact on the range of problems that can be addressed and on the types of system that can be studied. We discuss diffusing-wave spectroscopy (DWS), which extends DLS to very highly multiple scattering media. This technique extends the analytic power of DLS to opaque sample...

Dynamic laser speckle (DLS) analysis is a very sensitive technique to measure biological activity within samples. In agriculture, the applied monitor seed germination, but external light, water content, and pigments affect measurements. DLS systems use visible light sources, typically red lasers, which may exacerbate their influences. The main objective of this work assess whether infrared (IR)...
