WHAT IS BIOENGINEERING
Bioengineering is the application of the life sciences, physical sciences, mathematics and engineering principles to define and solve problems in biology, medicine, health care and other fields.
Bioengineering is a relatively new discipline that combines many aspects of traditional engineering fields such as chemical, electrical and mechanical engineering. Examples of bioengineering include:
artificial hips, knees and other joints
ultrasound, MRI and other medical imaging techniques
using engineered organisms for chemical and pharmaceutical manufacturing
Bioengineering graduates are employed by a variety of institutions, including medical device manufacturers, pharmaceutical companies, regulatory agencies and medical research institutions.
In addition, bioengineering graduates are prepared for continued study to pursue careers in medicine, law, business and other fields.
Biomedicine (i.e. medical biology) is a branch of medical science that applies biological and physiological principles to clinical practice.The branch especially applies to biology and physiology.Biomedicine also can relate to many other categories in health and biological related fields. It has been the dominant health system for more than a century.
It includes many biomedical disciplines and areas of specialty that typically contain the “bio-” prefix such as molecular biology, biochemistry, biotechnology, cell biology, embryology, nanobiotechnology, biological engineering, laboratory medical biology, cytogenetics, genetics, gene therapy, bioinformatics, biostatistics, systems biology, neuroscience, microbiology, virology, immunology, parasitology, physiology, pathology, anatomy, toxicology, and many others that generally concern life sciences as applied to medicine.
Biomedical engineering salary
The median annual wage for biomedical engineers is$85,620. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $51,050, and the highest 10 percent earned more than $134,620.
Molecular biology is the process of synthesis and regulation of a cell’s DNA, RNA, and protein. Molecular biology consists of different techniques including Polymerase chain reaction, Gel electrophoresis, and macromolecule blotting to manipulate DNA.
Polymerase chain reaction is done by placing a mixture of the desired DNA, DNA polymerase, primers, and nucleotide bases into a machine. The machine heats up and cools down at various temperatures to break the hydrogen bonds binding the DNA and allows the nucleotide bases to be added onto the two DNA templates after it has been separated.
Gel electrophoresis is a technique used to identify similar DNA between two unknown samples of DNA. This process is done by first preparing an agarose gel. This jelly-like sheet will have wells for DNA to be poured into. An electric current is applied so that the DNA, which is negatively charged due to its phosphate groups is attracted to the positive electrode. Different rows of DNA will move at different speeds because some DNA pieces are larger than others. Thus if two DNA samples show a similar pattern on the gel electrophoresis, one can tell that these DNA samples match.
