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.
With an invention that can be made from some of the same parts used in CD players, University of Michigan researchers have developed a way to measure the growth and drug susceptibility of individual bacterial cells without the use of a microscope.
To rebuild damaged parts of a human body from scratch is a dream that has long fired human imagination, from Mary Shelley's Doctor Frankenstein to modern day surgeons. Now, a team of European scientists, working in the frame of the EUREKA project ModPolEUV, has made a promising contribution to reconstructive surgery thanks to an original multidisciplinary approach matching cutting-edge medicine to the latest developments in nanotechnology.
