Biomaterials

Subject : engineering
Instructions:
  • Answer 18 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A type of biopolymer with linear bonded polymeric carbohydrate structures.






2. These are used in artificial hip joints - dental implants - bone plates and screws - heart pacemakers - stents - and other medical devices.






3. Type of biocomposites that consists of a matrix reinforced by a dispersed phase in form of particles.






4. Also known as hard materials and it usually has a mechanical function - being strong - hard materials which use less energy for an organism to produce than an equally strong organic material.






5. It functions as joint or tissue replacements - can be used as coatings to improve the biocompatibility of metal implants. They are also non - toxic and can be bioinert.






6. This involves the use of a binder or by using the thermal method to fuse the fibers together.






7. It is any material that - once placed in the human body - has minimal interaction with its surrounding tissue.






8. It is an analytical device for the detection of an analyte that combines a biological component with a physicochemical detector.






9. They are materials formed by a matrix (resin) and a reinforcement of natural fibers (usually derived from plants or cellulose).






10. A type of biopolymer with short polymers of amino acids.






11. A type of biopolymer with long polymers composed of 13 or more nucleotide monomers.






12. It is any substance (other than drugs) or combination of substances synthetic or natural in origin. It can be derived either from nature or synthesized in the laboratory using a variety of chemical approaches utilizing metallic components or ceramics






13. Materials which upon being placed within the human body interacts with the surrounding bone and in some cases - even soft tissue i.e. Synthetic hydroxyapatite - glass ceramic A-W - bioglass






14. This type of biomaterial processing is only useful if it preserves the uniform porous structure of the original membranes.






15. Type of biocomposites - a material which consists of voids/pores.






16. Materials that upon placement within the human body starts to dissolve (resorbed) and slowly replaced by advancing tissue (such as bone) i.e. tricalcium phosphate - polylactic- polyglycolic acid copolymers






17. They are also known as renewable polymers and these are produced from biomass for use in the packaging industry.






18. Type of biocomposites that consists of a matrix reinforced by a dispersed phase in form of discontinuous fibers.
