Nanotechnology is an emerging field of science and technology that offers a promising future in enhancing plant functions. Nano-bionics is a novel approach that innovatively integrates nanotechnology and plant biology. The recent era of agriculture needs sustainability to fulfill the demands of the growing population. In such cases, nano-bionics prove their worth, as they possess the ability to alter plant growth and development during stressed conditions positively. Moreover, the embedding of nanoparticles/nanomaterials into plant cells upgrades the functioning of plants, such as the induction of chemical sensing to monitor environmental changes and other hazards, promotion of light absorption capacity, and improvement of yield. Thus, nano-bionics can be considered a potential strategy to enhance sustainability in agriculture. However, ethical concerns and prior testing are still under consideration. This article discusses different types of nanomaterials used to design nano-bionics, the mechanism of nanomaterial/nanoparticle interaction, and applications of nano-bionics in detail.
