Andrew Maynard argues against defining engineered nanomaterials for regulatory purposes (Nature 475, 31; 2011). But such a definition is urgently needed, especially for particulate nanomaterials. The ...

Researchers have developed a noninvasive method to create light anywhere in the body. Their technique, which uses ultrasound waves to activate light-emitting nanoparticles, could be used to manipulate ...

Light has an increasing number of applications in biology and medicine—it can be used to stimulate cell growth, manipulate ...

Nanomaterials are, as defined by Standford University's Environmental Health & Safety Department as "materials with a minimum of one external dimension that ranges in size between 1-100 nanometers [2.

Nanomaterials (NMs) are increasingly used in everything from cosmetics to electronics, and their inevitable release into ...

In recent years, the application of nanomaterials in life science has gradually become a research hotspot. With the continuous development of nanotechnology, nanomaterials have attracted much ...

This starts at the chemical level: scientists can design a material’s structure to define how it reacts, binds, or transforms under specific conditions. Surface functionalization adds further ...

Cryo-transmission electron microscopy (cryo-TEM) allows us to observe samples in a preserved state that is close to their native form, making it a highly effective way to examine biological samples.

Since their discovery at Drexel University in 2011, MXenes — a family of nanomaterials with unique properties of durability, conductivity and filtration, among many others — has become the largest ...

Nanomaterials are poised for widespread use in the construction industry, where they can offer significant advantages for a variety of applications ranging from making more durable concrete to ...

Researchers at Stanford have developed a noninvasive method to create light anywhere in the body. Their technique, which uses ultrasound waves to activate light-emitting nanoparticles, could be used ...
