According To an article in Technology Review, this week for the first time a research team of the company Nanospectra Biosciences (one spinoff from Rice University) has Achieved a scientific breakthrough That will create a ” magic bullet”, something Researchers spent working on anticancer treatments years trying to develop. The concept is to create a bullet type That selects and destroys cancer cells.
Nanospectra team have developed gold plated glass nanoparticles capable of invading tumor and , When heated through a remote system , capable of destroying it . The key high degree of effectiveness of this new development is derived from the dimensions of the particles. The nanoparticles have a diameter of 150 nanometers , that Nanospectra the team , is the perfect size can pass through leaky Which Blood vessels of a tumor. Read the rest of this entry »
According to an article published in SmallTimes, the American authorities have just approved the use of a new treatment for breast cancer. The new drug is called Abraxane and is based on nanoparticles. According providers created with this new treatment nanotechnology, American Pharmaceutical Partners Inc. , in tests conducted Abraxane has been shown to be more effective and less toxic than Taxol.

When a person gets cancer, your body gives warning signals long before modern medicine is capable of detecting the disease. If you could detect these subtle changes before in human cells, have a greater chance of saving the patient. But the first changes at the molecular level in a person who is in the early stages of cancer are incredibly complex and may go unnoticed. Read the rest of this entry »
According to an article Nanotech.org, scientists at the Research Institute for Cell Engineering, National Institute of Advanced Science and Technology of Japan and the University of Tokyo Agriculture and Technology have used a nanoneedles bound atomic force microscopy to penetrate the core of living cells.
Researchers believe that these nanoneedles can be used to deliver molecules such as nucleic acids, proteins or other chemicals into the nucleus, or even to perform cell surgery. AFM needle tips could not be used as needles to not be long enough for the cells that were more than 3 microns (one thousandth of a mm.), So scientists created their own nanoneedles.

Some experts say new developments in nanotechnology could lead to immortality and modifying the genetic structure of the human cell.
Nanotechnology is a field of applied science , dedicated to the control and manipulation of matter on a scale smaller than one micrometre , ie at the level of atoms and molecules. It is common that such manipulation occurs in a range between one and one hundred nanometers. To get an idea of how small it may be a nanobot , nanobot plus or minus 50 nm is the size of 5 layers of molecules or atoms ( it depends on what is done nanobot ) .
Nano is a Greek prefix that indicates a measure , not an object , so that nanotechnology is characterized as essentially a multidisciplinary field , and united only by the scale of the material with which he works . Read the rest of this entry »
The editorial in leading scientific and medical journals in the world, Elsevier, has announced the upcoming release of the first journal in nanomedicine and use of the science of molecular devices to diagnose and treat disease. The publication is entitled Nanomedicine: Nanotechnology, Biology, and Medicine , and is the first official publication of the American Academy of Nanomedicine. Read the rest of this entry »
Nano Markets has just published two studies with a thorough analysis and future predictions about the role of nanotechnology in the field of medicine, particularly in the creation of new treatments and the drug delivery systems. The first study is called “Nano-Enabled Drug Discovery: Seven Technologies to Watch,” and analyzes the impact of several new nanotechnologies will have on the process of discovery of new medicines. The technologies covered in the study include. Read the rest of this entry »
An article Nanoworld section of The Washington Post, describes how nanotechnology might affect the food of the future. Teams of scientists are creating edible capsules that measure just a few nanometers to “improve” certain foods and create products such as smart drinks.
Nanoparticles are being self-mountable from materials found in foods. These nanoparticles “edible” can be manufactured in various shapes and are made of materials such as silicon or ceramics or materials such as polymers which can react to changes in temperature or body chemistry .

The section dedicated to nanotechnology in the edition of the newspaper THE WORLD restart his career, continuing its successful participation in the European project ‘NANO Channels’. This recovery occurs in a context fraught with uncertainty about the future , as it is found by looking the other sections of the newspaper. Perhaps the sections devoted to science and technology are, right now, which infuse more hope they show what human beings are capable of using resources wisely put in his hands.
It is these sections that should lean also those who design the model of country we aspire to have when the storm of cuts, impoverishment and corruption around us has become part of our fragile memory. Read the rest of this entry »
Some thoughts about nanotechnology, its economic impact and future strategies
Nanotechnology – Economy and future strategy
Scientists are making great strides in the study of nanoscale phenomena and in the attempt to gain greater control over matter. Nanotechnology allows scientists to manipulate the organic and inorganic matter atom by atom or molecule by molecule. The “nanoscience” potentially represents a revolution in the construction of devices with atomic precision. That is, the possibility of addressing the construction of new materials through the treatment of atoms and molecules as if they were “building blocks”.
Nanoscience is not intended as a step towards miniaturization. Potentially represents the possibility of achieving a convergence of quantum physics, molecular biology, chemistry, computer science and engineering. Read the rest of this entry »
