In this book we present ten chapters describing the synthesis and application of nanomaterials
for health food agriculture and bioremediation. Nanomaterials with unique properties are now
being used to improve food and agricultural production. Research on nanomaterials is indeed
revealing new applications that were once thought to be imaginary. Specifically applications
lead to higher crop productivity with nanofertilisers better packaging longer food shelf life
and better sensing of aromas and contaminants. these applications are needed in particular in
poor countries where food is scarce and the water quality bad. Nanotechnology also addresses
the age old issue of water polluted by industrial urban and agricultural pollutants. For
instance research produces nanomaterials that clean water more efficiently than classical
methods thus yielding water for drinking and irrigation. However some nanomaterials have been
found to be toxic. Therefore nanomaterials should be engineered to be safe for the
environment.
