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 article, we explore the individual concepts of biomimicry and nano-technology and then the combination of the both. The current review mainly focusses on nano innovations inspired by lotus leaf, gecko feet, butterfly wings, shark skin and peacock spider. We then look at the biological structures (more in nano-dimensions) from the entrenched interference patterns found on the butterfly wings inspiring in the development of display technologies to the self-cleaning properties of lotus that has resulted in the synthesis of nano materials having self-cleaning properties. In addition, insects like spiders which have inspired the most important inventions like optical devices, sensors, are also investigated. The challenges faced while implementing the biomimetic approach into technology are explained. We have also tried to shed light on the solutions which can tackle these challenges and issues.
