Modified phytoglycogen nanoparticles to protect oil in foods from oxidation

A researcher from Purdue University sucessfully modified the surface of phytoglycogen nanoparticles to make them behave “like an emulsifier, creating phytoglycogen octenyl succinate, or PG-OS. PG-OS is thicker and denser than commonly used emulsifiers, creating a better defense from oxygen, free radical and metal ions, which cause lipid oxidation“. His work also showed that ε-polylysine, a [...]

Nanotech versus biotech : visibility in “Le Monde” archive

This chart was built by searching the French newspaper “Le Monde” archive for articles mentioning nanotechnologies/biotechnologies. See this post for comparison with nanotech/biotech in the New York Times archive.

Nanotech versus biotech : visibility in the New York Times archive

This chart was built by searching the New York Times archive for articles mentioning nanotechnology/biotechnology. It can be clearly seen that biotech is a more mainstream subject (~5 to ~15 times more visible than nanotech) but is surprisingly losing visibility from year to year…

Carbon nanotubes can dramatically accelerate the germination and growth of plants

In the frame of a new study entitled “Carbon Nanotubes Are Able To Penetrate Plant Seed Coat and Dramatically Affect Seed Germination and Plant Growth“ recently published in the online edition of ACS Nano, researchers have demonstrated that carbon nanotubes can penetrate thick seed coat and support water uptake inside tomato seeds. According to some of [...]
