Combining Antibodies, Iron Nanoparticles and Magnets Steers Stem Cells to Injured Organs

Researchers at the Cedars-Sinai Heart Institute infused antibody-studded iron nanoparticles into the bloodstream to treat heart attack damage. The combined nanoparticle enabled precise localization of the body’s own stem cells to the injured heart muscle. The study addresses a central challenge in stem cell therapeutics: how to achieve targeted interactions between stem cells and injured cells.

Texas A&M Prof Helps To Develop New Device That Detects Radiation Better Than Ever

In a move that could have huge implications for national security, researchers have created a very sensitive and tiny detector that is capable of detecting radiation from various sources at room temperature. The detector is eight to nine orders of magnitude --100 million to as high as 1 billion -- times faster than the existing technology, and a Texas A&M University at Galveston professor is a key player in the discovery.

Doped Graphene Nanoribbons with Potential

Graphene is a semiconductor when prepared as an ultra-narrow ribbon – although the material is actually a conductive material. Researchers from Empa and the Max Planck Institute for Polymer Research have now developed a new method to selectively dope graphene molecules with nitrogen atoms. By seamlessly stringing together doped and undoped graphene pieces, they were able to form ”heterojunctions” in the nanoribbons, thereby fulfilling a basic requirement for electronic current to flow in only one direction when voltage is applied – the first step towards a graphene transistor. Furthermore, the team has successfully managed to remove graphene nanoribbons from the gold substrate on which they were grown and to transfer them onto a non-conductive material.

Simpler Process to Grow Germanium Nanowires Could Improve Lithium-Ion Batteries

Switzer-germanium-nanowires2.jpg

Researchers at Missouri University of Science and Technology have developed what they call “a simple, one-step method” to grow nanowires of germanium from an aqueous solution. Their process could make it more feasible to use germanium in lithium-ion batteries.

Introducing the Multi-Tasking Nanoparticle

Kit Lam and colleagues from UC Davis and other institutions have created dynamic nanoparticles (NPs) that could provide an arsenal of applications to diagnose and treat cancer. Built on an easy-to-make polymer, these particles can be used as contrast agents to light up tumors for MRI and PET scans or deliver chemo and other therapies to destroy tumors. In addition, the particles are biocompatible and have shown no toxicity. The study was published online today in Nature Communications.
