Nanoparticles technology > The Technology

Our technology is based on a proprietary process of nano-atomization. In the nano-atomization process, a liquid is aerosolized forming a cloud of sub-micron droplets.
 
The liquid contains the material to be nano-sized in the form of a solution or suspension in any desired solvent (i.e. water, ethanol, etc.).

Our nano-atomizer is unique in its qualities of:

• Droplets diameter

• Cloud density

• Droplet production conditions

 Droplet diameter

When measured at the point of birth of the droplets, the D₅₀ can be set anywhere within the following range: In water: 250nm-4.5µm; In ethanol: 150nm to 2.7µm. Around any selected droplet size within these ranges, a narrow size distribution (+/- 50nm) can be achieved.

Uniquely to our nano-atomizing process the formed droplets in the aerosol do not coalesce.

Cloud density

Our technology produces a highly dense cloud of 10¹¹-10¹² droplets/cm³.

In comparison, common pneumatic technologies produce 10⁵ droplets/cm³ (achieved at a high droplet velocity of about 100 m/sec), and common ultrasonic technologies typically produce 10⁶ droplets/cm³ .

Droplet production conditions

Unique process characteristics:

• The process requires no additives.

• The formed droplets do not coalesce.

• The aerosolization is achieved under ambient conditions of room temperature and atmospheric pressure.

• The process is cost effective: low energy consumption, no clogging of the aerosolizing medium, and therefore requires only minimal maintenance.
