For scientists to understand a system, they often push it to its limits. In geochemistry, that means putting minerals under extreme conditions and watching how they react.
Cornell University, in partnership with Memorial Sloan Kettering Cancer Center (MSKCC), is opening a new $10 million Center of Cancer Nanotechnology Excellence that brings together scientists, engineers, biologists and physicians to develop and translate new cancer care applications based on nanotechnology.
Nanotechnology is taking its first steps. Researchers from the Max Planck Institute for Intelligent Systems in Stuttgart have developed a gold nanocylinder equipped with discrete DNA strands as ‘feet’ that can walk across a DNA origami platform. They are able to trace the movements of the nanowalker, which is smaller than the optical resolution limit, by exciting plasmons in the gold nanocylinder.
Self-assembled DNA nanostructures can be used in molecular-scale diagnostics and as smart drug-delivery vehicles.
With a new federal grant of nearly $10.8 million over the next five years, Brown University researchers and students in the Superfund Research Program (SRP) will be able to advance their work studying how toxicant exposures affect health, how such exposures occur, how nanotechnologies could contain contamination, and how to make sure those technologies are safe.
Severin Schneebeli, a chemist from the University of Vermont, has discovered a new way to use chirality – an asymmetric property in identical structures – to make a nanoscale wrench.

Chemists at LMU have fabricated a novel nanosheet-based photonic crystal that changes color in response to moisture. The new material could form the basis for humidity-sensitive contactless control of interactive screens on digital devices.
Graphene, a one-atom thick lattice of carbon atoms, has been the focus of intense research since its discovery more than a decade ago. Effectively two-dimensional, graphene has unique physical properties and ultra-high conductivity and promises to revolutionize electronic devices as the ability to mass produce it grows.
Kathryn Whitehead, an assistant professor of chemical engineering at Carnegie Mellon University, has been named by Popular Science as a 2015 Brilliant Ten winner for her innovative work on drug delivery systems.
About BioMEMS and microsystems
BioMEMS assimilate miniature sensors, actuators, micro-optics, microfluidics, and structural elements with computation and controls for application in the healthcare sector. Microsystems are used in the healthcare sector for numerous applications. These devices improve the performance of medical devices by providing a competitive advantage to medical device manufacturers. For instance, the use of accelerometers has improved the treatment of cardiac diseases. Another instance being the use of MEMS and nanotechnology to improve drug delivery.
Whether triggered by cats, bees, pollen or mites, allergies are on the rise. And the bad news doesn't stop there. The only current therapy that treats their causes is allergen-specific immunotherapy -- or allergy shots -- which can cause severe side effects. Now, researchers report in Biomacromolecules the development of a potentially better allergy shot that uses nanocarriers to address these unwanted issues.
A team of scientists from the National University of Singapore (NUS) Faculty of Engineering has developed a wearable liquid-based microfluidic tactile sensor that is small, thin, highly flexible and durable. Simple and cost-effective to produce, this novel device is very suitable for applications such as soft robotics, wearable consumer electronics, smart medical prosthetic devices, as well as real-time healthcare monitoring.
A Clarkson University chemistry doctoral student has won a travel grant from the Electrochemical Society (ECS) to attend the biannual ECS Meeting in October in Phoenix, Ariz.
Nanowires are building blocks for next generation of electronics, photonics, sensors and energy applications. The major application of nanowires is in transparent conductors market whose value in 2014 was around US $ 3000 million. Asia pacific and North America are the leading markets for transparent conductors. So it is expected that these regions would be the leading markets for nanowires as well.
