HTTP:: Dosing to Be Replaced by Micro 039 Shuttles 039
--------
A new find is about to change the way medicine has been practiced over the past few centuries, experts from the Queen Mary, University of London have announced. The researchers have just finished developing their micro-shuttles, micro-particles that will be used to gradually deliver drugs to an affected area. This will eliminate the need for traditional dosing, which has been in use since the first drugs were created. Each of the new capsules has a diameter of only two micrometers, or roughly the size of a bacteria. They are obtained by wrapping strand after strand of metabolism-resistant material over a spherical particle, which is then dissolved using acid. The end-result is a sphere made of the material, but with an empty core, in which other substances, such as vaccines, genes, and others, can be placed. Filling the particles is done in a simple manner, by heating the empty containers in a solution that contains the required drug. As a result, the capsules shrink and !
trap some of the drug molecules inside. “The main advantage of using such microcapsules is that they can be designed to be very stable inside the body, protecting their contents. This is particularly important for the many medications that are rapidly degraded or altered by the body. These capsules can be used to 'store' drugs i...
