Computer chips contain silicon oxide, a substance that scientists once regarded as a mere insulator but now appears to be an active part of electronic processes that power cell phones, computers, and other products.
Researchers from Duke University Medical Center have identified how nanoparticles from diesel exhaust damage lung airway cells, a finding that could lead to new therapies for people susceptible to airway disease.
Producing molecules comparable with large bio-molecules in size, shape and structure is an age-old dream of organic chemists. An international research team has now succeeded in synthesising the biggest macromolecule to date.
Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have coaxed polymers to braid themselves into wispy nanoscale ropes that approach the structural complexity of biological materials.
CMOS processes currently used to manufacture logic and/ DRAM chips can open a whole new market of smart devices and microsystems. By integrating CMOS chip technology with sensors, actuators, passives, MEMS, optics, etc. smart devices with new functionalities can be developed.
Using a two-step process that creates gold nanoparticles that look like kernels of popcorn, researchers at Jackson State University have created a targeted nanoparticle that can detect as few as 50 malignant prostate cells and serve as a thermal scalpel that can kill the cells.
Scientists have shown that attaching the PHSCN peptide to a spherical polymeric nanoparticle increases the drug's potency by as much as 6,700 fold compared to the free drug in a test designed to measure breast cancer cell invasiveness.
An international research team from the United States and Italy has shown that it can use a new type of nanoparticle to selectively trap specific families of proteins from blood and protect them from degradation by enzymes in blood.
Nano-sized fluorescent particles known as quantum dots have shown promise as powerful imaging agents capable of detecting a wide range of diseases, but these nanoparticles are usually made with toxic metals such as cadmium. Now, researchers at the University of Buffalo have developed a novel synthetic method that enables them to design and create biocompatible fluorescent nanocrystals made of non-toxic silicon.
