|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 should be seen as a means of accelerating scientific discovery by providing free and unrestricted access of scientific knowledge via the Internet. An essential role of Open Access is the long-term preservation of peer-reviewed scholarly journal articles and research data. An Open Access publishing group focuses on to encourage innovation, socio-economic development, and flow of knowledge around the world. One such, Open Access is OMICS which is committed ultimately for public welfare to stimulate the growth of global science, as well as maintain the quality of scientific achievements at the same time. Bio crimes related articles are published in rice research open access journal, this journal publishes quality manuscripts which has good impact on the society.
