What is nano scale and how does it differ from traditional products?

Nano refers to the metric prefix for 10^-9  and means one-billionth of something. Nanoscience is the study of structures made small enough to take on new properties. For example, nano-particles of gold appear red in color and melt at significantly lower temperatures than normal gold slabs (~300 °C as compared to 1064 °C)[1].

Traditional products contain either:

  • Coarse particles with a diameter of 2,500 to 10,000 nanometers
  • Fine particles with a diameter of 100 to 2,500 nanometers.

Nualgi particles are 5 to 50 nanometers in diameter (1 millimeter = 1,000,000 nanometers).

Nano particles are known to have different properties than larger sized particles of the same element [2]. These tiny particles have a larger active surface area and can suspend themselves in liquid and are therefore more efficient by being bioavailable.

Bioavailability is a measurement of the rate and extent to which a drug or nutrient reaches the systemic circulation.  For example a drug injected intravenously is much more bioavailable as compared to a drug ingested orally.

For plants and organisms, it is a significant scientific challenge to provide nutrients in bioavailable form.  Nualgi is the only product of its kind that effectively addresses this challenge in a water body.  It’s nutrient particles are small enough to suspend themselves in the water column and are therefore more available for diatom algae to bloom.
