|Biomaterials for Tissue Engineering|
Registration: Open to all.
Biomaterials are defined as materials that are used in medical devices or are in contact with biological systems. Their application can range from skeletal systems (bone implants, knee joints, dental implants etc), cardiovascular systems (stents, catheter, heart valve etc), organs (artificial kidney, heart lung machine, skin etc) and senses (contact lens, corneal bandage etc). The field of biomaterials uses ideas from medicine, biology, physics, chemistry, materials sciences, engineering, ethics, law and health care. Biomaterials are usually integrated into devices or implants hence the interdisciplinary aspect is important for progress. The field brings together researchers from diverse academic backgrounds. They must communicate clearly. Some disciplines that intersect in the development, study and application of biomaterials include: bioengineer, chemist, chemical engineer, electrical engineer, mechanical engineer, materials scientist, biologist, microbiologist, physician, veterinarian, ethicist, nurse, lawyer, regulatory specialist and venture capitalist. Biomaterials can be metals, ceramics, polymers, glasses, carbons, and composite materials. Such materials are used as molded or machined parts, coatings, fibers, films, foams and fabrics. One of the major applications of biomaterials is in the field of tissue engineering. This field combines the knowledge of engineering, life sciences and clinical practice to solve the problem of tissue loss or damage, aimed at facilitating the regeneration of damaged or diseased tissue. The essence of tissue engineering is the use of living cells, together with degradable scaffolds and growth factors in development of implantable parts or devices for the restoration of body function. A major component in the revolutionary field of tissue engineering is the development of the suitable scaffold for seeding cells, growth factors and subsequent growth of tissues. There has been a considerable effort devoted to improving material and biological properties of scaffolds used in bone tissue engineering during the past decade. We developed and investigated different porous scaffolds with improved material properties and biological functions. An introduction to various scaffold materials developed in the lab along with future challenges will be presented towards the end.
