Advanced nanomaterials in agriculture under a changing climate: The way to the future?

•Global agricultural production suffers dramatic losses due to climate change-related phenomena.•Advanced nanomaterials represent a novel, sustainable solution to abiotic stress-induced yield loss.•Nanomaterials can be employed in the form of nanoparticles and/or seed polymer coatings.•Nanomaterials can lead to enhanced stress tolerance as well as growth promotion under control conditions. Global agricultural production is suffering substantial losses due to climate change-related phenomena such as drought and salinity, which lead to tissue damage and, ultimate, major yield losses. The development of sustainable, ‘green’ technologies is therefore becoming increasingly important. Nanotechnology provides invaluable tools to a variety of industrial sectors. Recent focus has been given to the development and optimization of nanomaterials for application in the agricultural industry towards improved growth, plant protection and overall performance based on their small size, high surface to volume ratio and unique optical properties. The present review provides an up-to-date description of advanced nanoparticles and polymers applied at plant and seed level, covering technical, biological and socioeconomical aspects of this promising approach. This technology offers an attractive alternative to established approaches such as conventional breeding and genetic modification with key advantages, representing a characteristic example of integrative plant physiology where multiple disciplines such as materials science, agriculture and analytical chemistry join forces to develop exciting new tools in modern agriculture.
