Nanonization (nano mill) is the process of creating or manipulating particles with sizes ranging from 1 nanometer to 100 nanometers.At the nanoscale, a lot of life can happen. It can be made in two ways: bottom-up and top-down. Vertical nano mill . Bottom-up refers to chemistry-based particle construction, whereas top-down refers to grinding or milling or grinding. While bottom-up ...

Nanomilling is the process by which the particle size of an API is reduced in a liquid vehicle (typically aqueous) via grinding using polymeric or ceramic media. Nanomilling is a proven, commercially validated process for formulating poorly water-soluble APIs. The key is the tremendous increase in surface area which directly correlates to an ...

Media milling is a continuous process wherein the drug suspension is pumped through the milling chamber to effect size reduction of the suspended material. Prior to their exit from the milling chamber, the milled particles pass through a screen that serves to separate the suspended, milled particles from the milling media.

Particle size reduction via micronization or nano-milling and amorphous solid dispersion technology via hot-melt extrusion or spray drying are often utilized to improve stability, flowability, dissolution rate and solubility. The choice of technology is dependent upon the …

There are basically two methods of producing nano-scale particles: the "Bottom-Up" technique involves synthesizing the particles from atoms and molecules. With the "Top-Down" method the particles are reduced to nanometer size by grinding. Suitable tools for this method are planetary ball mills, such as Retsch's new PM-series grinders, which provide the necessary energy input.
