The meaning of the word nanotechnology
Nano comes from the greek word meaning ‘dwarf’
Technical: refers to a reduction factor
1 nm= 10-9 = one billionth of a meter
Nanotechnology in food (PHL & HELHA group 6) 4
The meaning of the word nanotechnology
Nanotechnology is defined as:“ the investigation for phenomena and handling/process of materials at atomic, molecular and macromolecular scale.”
Macromolecular scale= nanoscale= sizes of 0,1 to 100 nanometers.

The meaning of the word nanotechnology
Official Starting point of nanotechnology: the lecture ‘Plenty of room at the bottom’ of Richard Feynmann in 1959.
However in 1905 Albert Einstein already found that the diameter of a sugar molecule was around 1 nm.
Already used for years: colored glass

Techniques used in agricultural production
Agricultural production is defined as:“ the processes to produce materials
(food, fuel and raw materials for other industries) from plant cultivation and raising domesticated animals.”
Nanotechnology in food (PHL & HELHA group 6) 17
Techniques used in agricultural production
Sensors and diagnostic devices Disease and pest control (nano-emulsions) Water and nutrient control (nano-clays) Genetic engineering of plants and
livestock to improve productivity Agriculture as a means to produce
nanomaterials
