WHAT IS BIOMIMETICS?
--BIOS=LIFE & MIMESIS=IMITATE
--BIOMIMETICS DEALS WITH THE DEVELOPMENT OF INNOVATIONS ON THE BASIS OF INVESTIGATION OF CHEMICAL/BIOLOGOCAL STRUCTURES, FUNTIONS, METHODS,PROCESSES AND SYSTEMS.
-- NATURE ACTS AS ‘THE MODEL’ IN OUR EFFORTS TOWARDS ADDRESSING HUMAN NEEDS.

Term coined by Otto H. Schmitt in 1969.
"taking design ideas from nature"

MIMICKING CAN BE DONE BY USING EITHER
Natural substitutes
or
Synthetic substitutes

Natural materials Synthetic materials
Less availabilityDifficulty in isolationReduced amenabilityRisk of pathogen

reaction when used as an implant.
More availabilityRelatively easier

pathogen transmission
Biocompatibility,biodegradability .
Why synthetic materials?

What can lotus teach us?
Unstickyness and hydrophobicity
unsticky or water resistant technology.

Nature inspired solutions are every where….
Energy usage buildings inspired by termite moulds.

Biomimic approach : In tissue engineering
Human tissue=Cells+ECM+signalling molecules
ECM=collagen+proteoglycan.
ECM play important role.

So artificial ECM can be made for regenerating cells or tissues
Naturally by choosing collagen and glucosaminoglycon from natural source.
OrSynthetic mimics with similar structure or function (ex:chitosan and gelatin hydrogel) are used.

Other recent projects…
combat.
Artificial human organs.
human robots and many more.
