Comes the smart pill - 0 views

  •  
    "Engineers at the University of Florida (USA) have created a housing that incorporates a tiny microchip and antenna and, after administration, warns that a patient has taken his medicine. According to Rizwan Bashirullah, creator of the invention, the smart pill could be very useful in patients who forget if you have taken medication, or just clueless and do not take it daily. The pill consists of a capsule containing a microchip and an antenna that is printed on its surface using non-toxic ink of silver nanoparticles . The antenna is biocompatible and dissolves almost 100%. When the pill is swallowed, the microchip is communicated to a small external electronic device (which could be incorporated into future mobile phone), which in turn sends a message to a phone or a computer, informing both the patient and the doctors and family members if necessary. According to the American Heart Association, the main problem in treating illness today is that no medical requirements are met . Recent studies show that chronically ill patients only take half of the pills prescribed . And that 10% of hospital admissions due to this lack of consistency. Even 218,000 deaths annually are attributed to this problem. "Using technology to remedy may be a good idea," says Bashirullah."

    "Nanotechnology medical developments over the coming years will have a wide variety of uses and could potentially save a great number of lives. Nanotechnology is already moving from being used in passive structures to active structures, through more targeted drug therapies or "smart drugs." These new drug therapies have already been shown to cause fewer side effects and be more effective than traditional therapies. In the future, nanotechnology will also aid in the formation of molecular systems that may be strikingly similar to living systems. These molecular structures could be the basis for the regeneration or replacement of body parts that are currently lost to infection, accident, or disease. These predictions for the future have great significance not only in encouraging nanotechnology research and development but also in determining a means of oversight. The number of products approaching the FDA approval and review process is likely to grow as time moves forward and as new nanotechnology medical applications are developed."

Nanotechnology Introduction - 0 views

  •  
    "The term "nanotechnology" has evolved over the years via terminology drift to mean "anything smaller than microtechnology," such as nano powders, and other things that are nanoscale in size, but not referring to mechanisms that have been purposefully built from nanoscale components. See our "Current Uses" page for examples. This evolved version of the term is more properly labeled "nanoscale bulk technology," while the original meaning is now more properly labeled "molecular nanotechnology" (MNT), or "nanoscale engineering," or "molecular mechanics," or "molecular machine systems," or "molecular manufacturing." Recently, the Foresight Institute has suggested an alternate term to represent the original meaning of nanotechnology"

    "A nanoparticle (or nanopowder or nanocluster or nanocrystal) is a microscopic particle with at least one dimension less than 100 nm. Nanoparticle research is currently an area of intense scientific research, due to a wide variety of potential applications in biomedical, optical, and electronic fields. Nanoparticles are of great scientific interest as they are effectively a bridge between bulk materials and atomic or molecular structures. A bulk material should have constant physical properties"

Nanotechnology Delivers Microcoatings | EMDT - European Medical Device Technology - 0 views

  • In the field of medical device development there are a number of factors generally recognised as being important for success. Among these are the biocompatibility, sterility, reliability and adaptability of materials to their surroundings. Without a suitable approach to these issues, the majority of medical devices will not be as successful as they could be. Biocompatibility of materials, in particular, is a critical factor in the development and application of permanent and temporary implants and other devices such as catheters and tubes that are to be used in and around the body. Coating technology is the obvious and ideal solution for separating the bulk properties of a material or device from direct interaction with its surroundings. The independent modification of surface and bulk properties widens the range of features that can be incorporated into products. Bulk properties are responsible for characteristics such as mechanical strength. A suitable coating will enhance the interaction of the device with its surroundings. For example, it will provide drug-elusion (stents), anti-fouling and antibacterial properties, and a hydrophobic self-cleaning surface, referred to as lotus coating.1 The lotus effect in material science is the observed self-cleaning property found with lotus plants. A coating with this effect will make surfaces self-cleaning and will decrease the need for active cleaning of the subsequent surface; it may even enhance the sterility of surfaces. Recently there have been some interesting developments in materials and coatings based on organic and inorganic components, which are responsible for current state-of-the-art devices. Examples include coatings for stents that provide multiple therapeutic effects in thinner layers and coatings with better adhesion to device surfaces. The future holds the promise of even greater functionality for medical coatings.

    nanotechnology is a branch off of nanotechnology. they are small machines that can be used for anything. "Nanorobotics is the emerging technology field creating machines or robots whose components are at or close to the scale of a nanometer (10−9 meters).[1][2][3] More specifically, nanorobotics refers to the nanotechnology engineering discipline of designing and building nanorobots, with devices ranging in size from 0.1-10 micrometers and constructed of nanoscale or molecular components.[4][5] The names nanobots, nanoids, nanites, nanomachines or nanomites have also been used to describe these devices currently under research and development"

What is Nanotechnology? - 0 views

    the term nanotechnology was coined back in the 80s by K. Eric Drexler. I'm sure at the time it wasn't much more than a science fiction dream, but now it is a very real technology. "When K. Eric Drexler (right) popularized the word 'nanotechnology' in the 1980's, he was talking about building machines on the scale of molecules, a few nanometers wide-motors, robot arms, and even whole computers, far smaller than a cell. Drexler spent the next ten years describing and analyzing these incredible devices, and responding to accusations of science fiction. Meanwhile, mundane technology was developing the ability to build simple structures on a molecular scale. As nanotechnology became an accepted concept, the meaning of the word shifted to encompass the simpler kinds of nanometer-scale technology. The U.S. National Nanotechnology Initiative was created to fund this kind of nanotech: their definition includes anything smaller than 100 nanometers with novel properties."

    nanotechnology is an interesting concept. many world governments have invested billions in research for nanotechnology. "Nanotechnology (sometimes shortened to "nanotech") is the manipulation of matter on an atomic, molecular, and supramolecular scale. The earliest, widespread description of nanotechnology[1][2] referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers. This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter that occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size. Because of the variety of potential applications (including industrial and military), governments have invested billions of dollars in nanotechnology research. Through its National Nanotechnology Initiative, the USA has invested 3.7 billion dollars. The European Union has invested 1.2 billion and Japan 750 million dollars."

    A nanometer is one billionth of a meter. this means that when nanomites they will be so small that we wont even e able to see them through a microscope. "In order to understand the unusual world of nanotechnology, we need to get an idea of the units of measure involved. A centimeter is one-hundredth of a meter, a millimeter is one-thousandth of a meter, and a micrometer is one-millionth of a meter, but all of these are still huge compared to the nanoscale. A nanometer (nm) is one-billionth of a meter, smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair"
