what are the overviews of biomaterial as in the figure you can see that the biomaterials are the substances or the materials that are designed to interact with biological systems for medical therapeutic diagnostic or research purpose these materials can be natural or synthetic and are used in various applications including implants Prosthetics tissue engineering and Drug delivery now what is the definition of biomaterial a biomaterial is any material natural or man-made that is intended to interface with biological systems to repair replace or enhance biological functions so they are engineered to be biocompatible meaning they can perform their function without causing adverse reactions in the body now when you talk of the properties of the biomaterial biomaterials are com biocompatibility it has uh the properties like strength flexibility durability and some biom materials are designed to degrade over time while other are meant to be per permanent when you talk of the surface property the surface of biomaterial should support cell addition and tissue integration and minimization rejection if we talk of biomaterials uh must withstand sterilization process to prevent in infections now what are the characteristics of a bii they must be biocompatible if you talk of uh the material they must not induce toxic or immune response when used in the body when you talk of the mechanical properties biomaterial must have appropriate strength flexibility and durability to perform in biological envir enir Ms degradability some biomaterials are designed to degrade over time and uh when you talk of the characteristics we also have the properties the surface of biomaterial should support cell addition and tissue integration minimizing rejection biomaterial must withstand sterilization process this already we discussed in our previous slide now when you talk of the types of the biom materials we we have the natural biomaterials the natural biomaterials are derived from natural sources for example collagen silk so these are the examples of biomaterials they often support better cell addition and tissue regenerations such as the wound dressing so these are the examples of natural biomaterials when you talk of the metallic biomaterial metals like uh the typ titanium steel titanium steel stainless steel Cobalt chromium Alloys they are used for strength and corrosion resistance they are commonly used in Orthopedic implants dental implants and cardiovascular stems now comes the polymeric biomaterial synthetic polymers like polythene poly actic acids and polymethyl methy clarate they are used in applications like artificial organs drug delivery system and soft tissue replacement so as you can see in the image the polymer materials are further classified as hydrogels injectable hydrogels Plastics bionics polymer sponges and polymeric films so these are used for various types of application like drug delivery skin tissue engineering then you have bone tissue engineering cartilage tissue engineering Coria tissue engineering and we have cardio tissue engineering so these type in the medical applications the polymer biomaterials are been used now when we talk of this ceramic biomaterial they are uh basically uh used for the bone grafting Dental restoration and coating for implants the Ceramics like Hydro oxylite zironia they are biocompatible and ve resistant so these are some of the uh bioceramic materials being uh shown in the powdered form then after that comes the composite biomaterials Composite biom Materials consist of two or more materials to leverage the best properties of each so there are examples of uh the biomaterials like carbon fiber reinforced polymers bone scaffolds as you can see in the image we have uh the multiscale composite we have the different different types enamels synthetic composites composite electric pump fibers dentals now when you conclude this biomaterial topic materials are revolutionized healthc care enabling breakthrough in medical devices regenerative medicines and Drug delivery as advancement in Material Science continues so biomaterial will play as increasingly vital role in improving the human health and the quality of life thank you
