Nature mimicry rather, biomimicry is one such field being considered for the backbone of the most astounding inventions in recent science and technology. Biomimicry combined with nanotechnology developed many sustainable solutions to satisfy problems existing in daily life. In this presentation, we explore the individual concepts of biomimicry and nano-technology

13. • Nature has always been a role model for human beings and imitating the various creations of nature
helps us to solve our problems easily.
• Biomimicry uses nature as a measure. Nature is used to judge the “rightness” of our innovations.
• Biomimicry helps us view and value nature because of the various innovations that are developed
keeping nature in mind. Hence, we view nature as a mentor.
