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.
Term coined by Otto H. Schmitt in 1969."taking design ideas from nature"
MIMICKING CAN BE DONE BY USINGEITHERNatural substitutes or Synthetic substitutes
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 .
Structural Functional Structural-functional Biological process mimicking.
What can lotus teach us?Unstickyness and hydrophobicity unsticky or water resistant technology.
Nature inspired solutions areevery where…. Energy usage buildings inspired by termite moulds.
Coloured butterfly wings inspired the reflectivewindows. Slide 20
Biomimic approach : In tissueengineeringHuman tissue=Cells+ECM+signalling moleculesECM=collagen+proteoglycan.ECM play important role.
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.
Other recent projects… combat.Artificial human organs. human robots and many more.
