Mitochondria are often referred to as the powerhouses of our cells, because they generate chemical energy similar to that obtained from a battery. Whether it's a brain, muscle or plant cell, nano-sized gateways control the activity of the mitochondrial battery, by carefully allowing certain proteins and other molecules to enter into our mitochondria. Some of these proteins are large and complex molecules, yet they are essentially "spirited" into from the cytoplasm into the mitochondria, while the mitochondrial membrane remains water-tight and intact. How this happens has confounded science for decades.
TowerJazz, the global specialty foundry leader, and TowerJazz Panasonic Semiconductor Co., Ltd. (TPSCo), the leading analog foundry in Japan, today announced the development of the first 65nm millimeter wave (mmWave) 110GHz RFCMOS platform targeted for a variety of applications, such as wireless communication (60~77GHz), automotive radar (57~86, mostly 77GHz), and imaging and scanning (100GHz), among others.
With fossil-fuel sources dwindling, better biofuel cell design is a strong candidate in the energy field. In research published in the Journal of the American Chemical Society, Los Alamos researchers and external collaborators synthesized and characterized a new DNA-templated gold nanocluster (AuNC) that could resolve a critical methodological barrier for efficient biofuel cell design.
A detailed nano-mechanical study of mechanical degradation processes in silicon structures containing varying levels of lithium ions offers good news for researchers attempting to develop reliable next-generation rechargeable batteries using silicon-based electrodes.
Covalent organic frameworks (COFs) are a class of porous polymers that enable the atomically precise incorporation of organic units into periodic structures, creating highly ordered ð-columnar arrays and one-dimensional open channels. One significant structural feature is that they can be predesigned at both primary and high-order structure levels. COFs have emerged as a platform for materials design and functional explorations. However, their low stability has been impeded any practical implementations.
Two North Dakota State University researchers have received a National Institutes of Health grant award to study ways to use polymer spheres to deliver anticancer drugs to combat prostate cancers.
Celator Pharmaceuticals, Inc., a biopharmaceutical company that is transforming the science of combination therapy and developing products to improve patient outcomes in cancer, announced their successful R&D efforts to apply the CombiPlex® technology platform to optimize the efficacy of anticancer drug combinations incorporating molecularly targeted agents (MTAs).
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.
