Sugar-coated nanosheets developed to selectively target pathogens

Science Daily  March 29, 2018 A team of researchers in the US (Lawrence Berkeley National Laboratory, New York University) created the synthesized nanosheets out of self-assembling, bio-inspired polymers called peptoids. The sheets were designed to present simple sugars in a patterned way along their surfaces. Picking the right sugars to bind to the peptoid nanosheets, in the right distributions, can determine which pathogens will be drawn to them. They confirmed that the bindings with the targeted proteins were successful. The peptoid platform is rugged and stable, it can be deployed into the field for tests of bioagents by military personnel […]

Magnetic nanoparticles will help stop internal bleeding 15 times more effectively

Nanowerk  February 28, 2018 Researchers in Russia used magnet-driven nanoparticles consisting of two key components – thrombin, an enzyme responsible for blood clotting and magnetite. Thrombin interacts with the protein called fibrinogen and triggers clot formation to block the damaged vessel. The thrombin is wrapped into a special porous matrix made of magnetite that allows for precise control of the movement of particles inside the body using an external magnetic field. A drug based on these nanoparticles is nontoxic and can be injected intravenously and delivered straight to the site of a vascular injury. It can accelerate local clot formation […]
