Disadvantages of SPMNPs

In spite of the very exciting properties SPMNPs can offer, there are still several problems associated with using these nanoparticles in cancer diagnostics and therapeutics, especially for magnetically targeted drug delivery (Lubbe et al. 1999). The first limitation lies in the use of magnets for attracting superparamagnetic particles. When dealing with the tumors which have a large distance to possibly position the magnets, magnetic field strength at the tumor site will not be enough to attract the SPMNPs. Secondly, occlusion of blood vessels can occur in the target regions as the result of the high accumulation of magnetic carriers. In addition, toxic responses of the body to the SPMNPs can also hinder the application of such particles. All of these potential disadvantages need to be carefully considered.

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
