2. WHAT IS BIOMIMETICS? --BIOS=LIFE & MIMESIS=IMITATE--BIOMIMETICS DEALS WITH THE DEVELOPMENT OFINNOVATIONS ON THE BASIS OF INVESTIGATION OFCHEMICAL/BIOLOGOCALSTRUCTURES, FUNTIONS, METHODS,PROCESSES ANDSYSTEMS.-- NATURE ACTS AS ‘THE MODEL’ IN OUR EFFORTSTOWARDS ADDRESSING HUMAN NEEDS.
3. Term coined by Otto H. Schmitt in 1969."taking design ideas from nature"
4. MIMICKING CAN BE DONE BY USINGEITHERNatural substitutes or Synthetic substitutes
5. Why synthetic materials?Natural materials Synthetic materials Less availability  More availability Difficulty in isolation  Relatively easier Reduced amenability synthesis Risk of pathogen  Tailorability transmission  Reduced risk of Immunogenic reaction pathogen transmission when used as an  Biocompatibility,biode implant. gradability .
6.  Structural Functional Structural-functional Biological process mimicking.
7. What can lotus teach us?Unstickyness and hydrophobicity unsticky or water resistant technology.
8. Nature inspired solutions areevery where…. Energy usage buildings inspired by termite moulds.
9. Bionic car inspired by the boxfish.
10. Bullet train motion inspired bykingfisher.
11. Coloured butterfly wings inspired the reflectivewindows. Slide 20
12. Biomimic approach : In tissueengineeringHuman tissue=Cells+ECM+signalling moleculesECM=collagen+proteoglycan.ECM play important role.
13. So artificial ECM can be madefor regenerating cells or tissuesNaturally by choosing collagen andglucosaminoglycon from natural source. OrSynthetic mimics with similar structure orfunction (ex:chitosan and gelatin hydrogel) areused.
