Which of the following classes of biomaterials would be most appropriate for use to fabricate an artificial tendon, a tissue that must sustain substantial deformation at low forces and return rapidly to its original dimensions upon release of the stress why?1. metals2. ceramics3. polymers

Polymers

Explanation:

- Polymer substrates are the main components in this tissue engineering. Polymer substrates provide the essential factors for physiological regeneration process. Polymer scaffolds are combination of polymers with, drugs, cells, can be used for therapeutic treatment of diseases and also for regeneration of several vital organs of human body such as ear, blood vessels, coronary artery etc.

- Some of the useful properties of various engineering polymers are high strength or modulus to weight ratios (light weight but comparatively stiff and strong), toughness, resilience, resistance to corrosion, lack of conductivity (heat and electrical), color, transparency, processing, and low cost.
