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

transmissionImmunogenic

reaction when used as an implant.

More availabilityRelatively easier

synthesisTailorabilityReduced risk of

pathogen transmission

Biocompatibility,biodegradability .

Why synthetic materials?

Structural Functional Structural-functional Biological process mimicking.

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.

Bionic car inspired by the box fish.

Road studs inspired by eye shine reflection of cats.

Bullet train motion inspired by kingfisher.

Coloured butterfly wings inspired the reflective windows.

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.
