Nanofabrication Techniques for Controlled Drug Released Devices
Lei Chen, Gerard Henein, Vincent K. Luciani
New drugs and delivery systems have undergone a rapid development in recent years for treating cancer, HIV aids, diseased organs, damaged nerves to relieve pain, prevent disease and restore health to human beings. The application of nanofabrication in nanomedicne for drug-delivery is a new field and has raised great attention. Compared to conventional drug delivery mechanisms, nano-scale systems can deliver the drugs to diseased cells directly and minimize damage to healthy cells and they can also be made small enough to be implantable in the body. Alternatively, by modifying the shells of the drug, shells can release the drug automatically under certain stimuli. Nanoscale controlled release drug systems provide highly selective and effective therapeutic modalities.
