Medicine is by means of biotechnology techniques so much in diagnosing and treating dissimilar diseases. It also gives an opportunity for the population to defend themselves from hazardous diseases. The pasture of biotechnology, genetic engineering, has introduced techniques like gene therapy, recombinant DNA technology, and polymerase chain report which employ genes and DNA molecules to make a diagnosis diseases and put in new and strong genes in the body which put back the injured cells. There are some applications of biotechnology which are live their part in the turf of medicine and giving good results. Application of engineering principles and design concepts to medicine and biology for healthcare purposes (e.g. diagnostic or therapeutic). This field seeks to close the gap between engineering and medicine. It combines the design and problem-solving skills of engineering with medical and biological sciences to advance health care treatment, including diagnosis, monitoring, and therapy. Prominent biomedical engineering applications include the development of biocompatible prostheses, various diagnostic and therapeutic medical devices ranging from clinical equipment to micro-implants, common imaging equipment such as MRIs and EEGs, regenerative tissue growth, pharmaceutical drugs and therapeutic biological.
