Nanosafety Research: The Quest for the Gold Standard

Empa toxicologist Harald Krug has lambasted his colleagues in the journal Angewandte Chemie. He evaluated several thousand studies on the risks associated with nanoparticles and discovered no end of shortcomings: poorly prepared experiments and results that don’t carry any clout. Instead of merely leveling criticism, however, Empa is also developing new standards for such experiments within an international Network.

New Nanodevice to Improve Cancer Treatment Monitoring

4903-mesurer-methotrexate.jpg

In less than a minute, a miniature device developed at the University of Montreal can measure a patient's blood for methotrexate, a commonly used but potentially toxic cancer drug. Just as accurate and ten times less expensive than equipment currently used in hospitals, this nanoscale device has an optical system that can rapidly gauge the optimal dose of methotrexate a patient needs, while minimizing the drug's adverse effects.

In Orbit or on Earth, Implantable Device Will Be Commanded to Release Therapeutic Drugs Remotely

nDS-hi.jpg

Scientists will receive about $1.25 million from the Center for the Advancement of Science in Space to develop an implantable device that delivers therapeutic drugs at a rate guided by remote control. The device's effectiveness will be tested aboard the International Space Station and on Earth's surface.

Nanoparticle-Based Invention Moves New Drugs Closer to Clinical Testing

Penn State College of Medicine researchers have developed a nanoparticle to deliver a melanoma-fighting drug directly to the cancer. Delivering cancer drugs directly to tumors is difficult. Scientists are working on new approaches to overcome the natural limitations of drugs, including loading them into nanoparticles.

See-Through, One-Atom-Thick, Carbon Electrodes Powerful Tool to Study Brain Disorders

LittNatCommsarrayOct14pic.jpg

A graphene, one-atom-thick microelectrode now solves a major problem for investigators looking at brain circuitry. Pinning down the details of how individual neural circuits operate in epilepsy and other brain disorders requires real-time observation of their locations, firing patterns, and other factors.

Goldilocks Principle Wrong for Particle Assembly: Too Hot & Too Cold Is Just Right

LangNatureMaterials2014.jpg

Microscopic particles that bind under low temperatures will melt as temperatures rise to moderate levels, but re-connect under hotter conditions, a team of New York University scientists has found. Their discovery points to new ways to create “smart materials,” cutting-edge materials that adapt to their environment by taking new forms, and to sharpen the detail of 3D printing.

Researchers Develop World’s Thinnest Electric Generator

Hone-WangGTPiezoelectricMoS2Naturepaperimage.png

Researchers from Columbia Engineering and the Georgia Institute of Technology report today that they have made the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2), resulting in a unique electric generator and mechanosensation devices that are optically transparent, extremely light, and very bendable and stretchable.

Beyond LEDs: Brighter, New Energy -Saving Flat Panel Lights Based on Carbon Nanotubes

planarlight-1_1.jpg

Scientists from Tohoku University in Japan have developed a new type of energy-efficient flat light source based on carbon nanotubes with very low power consumption of around 0.1 Watt for every hour’s operation--about a hundred times lower than that of an LED.

Plasmonic Paper

AVS-plasmonic-Singamaneni.jpg

Using a common laboratory filter paper decorated with gold nanoparticles, researchers have created a unique platform, known as “plasmonic paper,” for detecting and characterizing even trace amounts of chemicals and biologically important molecules—from explosives, chemical warfare agents and environmental pollutants to disease markers. The work will be described at the AVS 61th International Symposium and Exhibition.
