Addressing the hazard potential of 2D nanomaterials

Nanowerk.com - 19 июня, 2018 - 16:36
A new paper reviews the studies to date that have addressed the toxicity of 2D materials, particularly emphasizing the preparation methods and resulting physicochemical properties that dictate their interactions with biological systems. In addition, due to its importance in determining exposure risk, this review summarizes key results from the literature concerning the environmental fate of 2D materials. The authors hope that a thorough understanding of these issues will inform ongoing efforts to realize the design of safer 2D materials.

Scientists create continuously emitting microlasers with nanoparticle-coated beads

ScienceDaily.com: Nanotechnology News - 18 июня, 2018 - 18:30
Researchers have found a way to convert nanoparticle-coated microscopic beads into lasers smaller than red blood cells. These microlasers, which convert infrared light into light at higher frequencies, are among the smallest continuously emitting lasers of their kind ever reported and can constantly and stably emit light for hours at a time, even when submerged in biological fluids such as blood serum.
