Life sciences controlled release drugs

A different but very important area of chemical engineering in the life sciences involves the design and manufacture of health care systems for diagnostic or therapeutic purposes. Consider the example of controlled release drugs or dermal penetration drugs. Here the emphasis is on the system rather than on the compound. The design of these systems requires an understanding of reactions, kinetics, fluid mechanics, and membrane systems. 

SPQR can be used to provide mechanistic information about chemical and enzymatic reactions. They are useful in the prediction of chemical reactivities and properties, of physical properties and of biological activities. This has led to their very extensive use in the design of medicinal drugs and pesticides. This involves not only maximization of activity and minimization of side effects, but desirable properties such as improved solubility, longer shelf life and controlled release. They have also become an important method in environmental science, where they can be used to predict toxicities and other properties of environmental interest. Finally, SPQR provide an effective, efficient and convenient method for storing the experimental results of studies on the variation of measured properties as a function of structural change. 

From dental repairs to controlled drug release or total organ/joint replacement, almost every human being on earth will be exposed to one biomaterial or another during their lifetime. Artificial organs are necessary to support part or all of their essential functions thereby improving quality of life. In biomaterial science, interaction between biomaterials and natural tissues is still an important subject. The informations are essential to aid the design of new biocompatible materials.
