Biomaterials are substances engineered to interface with the body for therapeutic or diagnostic purposes. Traditionally these include metals (eg. hip implants), ceramics (eg. dental implants) and polymers (eg. vascular grafts), but can also include complex materials such as decellularized tissue, engineered cell sheets, nanoparticles, etc. Bioinspired materials are materials inspired by nature. These have diverse applications, ranging from health applications and biosensing to food manufacture and defence.
