Nanoparticles must be first dispersed in a liquid to be used effectively, and over the past few years, the use of fine bead mills for grinding and dispersion of these particles has become more and more prevalent. Fine bead mills, widely used in both laboratory and production applications, deliver an efficient
Nanoparticles of zinc oxide (ZnO) are increasingly recognized for their utility in biological applications. In this study, the high-energy ball milling (HEBM) technique was used to produce nanoparticles of ZnO from its microcrystalline powder. Four samples were ball milled for 2, 10, 20, and 50 hours, respectively.
The application of ultrasonic dispersion of nanoparticles has manifold effects. The most obvious is the dispersing of materials in liquids in order to break particle agglomerates. Another process is the application of ultrasound during particle synthesis or precipitation.Generally, this leads to smaller particles and increased size uniformity.

These test results show that Planetary Ball Mills from FRITSCH can be used to produce nanoparticles. Using FRITSCH technology, a "boulder" can be turned into nanoparticles in just 1 hour, as an intermediate sample after 30 minutes yielded results of x10 < 180 nm - x50 < 250 nm and x90 < 580 nm. Critical Factors for Production of Nanoparticles
The mill commonly used to reliably reduce coarse particles to nanosize — whether by dispersion or comminution — is the agitator bead mill, as shown in Figure 1. An agitator bead mill consists of a grinding chamber, an agitator consisting of a rotating shaft equipped with agitator elements, a drive motor, and a media separator (located at ...
Green synthesis of AuNPs from a plant. Plant extract and metal salt solution HAuCl 4 were mixed. After that, the resultant solution is centrifuged, which results in the bio reduction of metallic ions to AuNPs. Phytochemicals act as reducing, as well as stabilizing/capping, agents in this process.
We were one of the first companies to scale and commercialize a nanoparticle with our work on zinc oxide (Z-Cote®) for skincare products in 1990s. Over the years, our scientists have worked on hundreds of nanoparticulate projects, including highly potent APIs and controlled substances.
