Drug delivery systems are engineered technologies for the targeted delivery and/or controlled release of therapeutic agents. Drugs have long been used to improve health and extend lives. The practice of drug delivery has changed dramatically in the last few decades and even greater changes are anticipated in the near future. Biomedical engineers have not only contributed substantially to our understanding of the physiological barriers to efficient drug delivery-such as transport in the circulatory system and drug movement through cells and tissues-they have contributed to the development of a number of new modes of drug delivery that have entered clinical practice. Drug delivery systems control the rate at which a drug is released and the location in the body where it is released. Some systems can control both.
Open access journal articles are essentially peer-reviewed and available for access through the directory of Open Access journals. OMICS Group International supports this system and provides access to 700+ peer-reviewed journals with no restrictions and thus promotes the Open Access movement with a view to promote scientific advancements. The research articles published in OMICS Group journals are immediately and permanently available online without charge.
