Scientists are reporting an advance in overcoming a major barrier to the use of the genetic material RNA in nanotechnology - the field that involves building machines thousands of times smaller than the width of a human hair and now is dominated by its cousin, DNA.
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.
