Advantages And Disadvantages Of Chemical Engineering

” was developed for producing various types of human tissues.
• A biocompatible material ( Poly-acryl-amide ) when subjected to small change in solvent concentration, acidity, light ,magnetic field or temperature these gels swell to hundred times their original size or shrink in volume at max 90%.
• A chemical engineer ‘Allan Hoffman’ from MIT, prepared the first pure radiation –cross linked gel for use in medical applications.
Now a days dentist used biocompatible material for making artificial jaws and teeth. Plastic bottles, poly-bags, headphones, computer body etc. are manufactured. For large scale production of these materials in cost reducing and quality improving way, many chemical engineers are required. Hence chemical engineering principle is

To increase both safety and to make drug delivery easy within the body, chemical engineering and biomedical communities have devised a variety of improved drug delivery techniques. To design methods that can guarantee the delivery of precise, dosages to minimize the risk for overdose or insufficient dosing are some of the challenges of chemical engineers.
A chemical engineer Robert Langer, and his colleagues discovered that when there is mixing of hydrophobic polymers such as ethylene acetate and lactic glycolic acid under appropriate conditions, highly porous structures can be formed by which specific molecules can be released for hundred days. In recent years targeted drug delivery has become an issue of discovery in biomedical and chemical engineering departments. Principle of chemical engineering related to polymer processing, diffusion and mass transfer phenomena have played an integral part in the design development, manufacture and use of novel drug delivery vehicles which are based on biocompatible, biodegradable polymers.
