Researchers at North Carolina State University...
have created a new type of eco－friendly
nanoparticle... to be used in pesticides.
It′s made with lignin，... an organic polymer
found in nearly all plants and trees.
The team discovered that it could replace
the silver－based nanoparticles，... currently
used in pesticides， which are considered
damaging to the environment... as they leave
behind a metallic， silver core.
″Our idea， or our approach， was to see
if we can， if this is the problem， we
replace the metallic core， which doesn′t
participate in microbial action， with a
biodegradable core.″
Researchers were able to synthesize the lignin
nanoparticle... and infuse it with silver
ions... to replicate the anti－microbial
properties of silver... while also allowing
it to be degradable.
The team says their discovery could reduce
the many hazardous chemicals used in traditional
pesticides and improve crops.
And that does it for you international news
at this hour， I′ll see you right back
here tomorrow.
