Providing an insight into nano-enabled agriculture

A range of nano-enabled strategies can address existing inefficiencies in agrochemical delivery and activity. Many of these approaches for plant protection and nutrition involve foliar application of engineered nanomaterials, which can also be used to enhance plant resilience and to enable biofortification. Nanotechnology clearly holds great promise for crop production, helping to sustainably meet the growing global demands for food, feed and fuel. The cover art depicts nanoparticles deposited on a leaf, interacting with the unique surface environment and subsequently entering the vascular system to deliver novel functionality to the entire plant.

    While measurement of an electron spin commonly destroys it, the quantum non-demolition measurement implemented here for an electron spin qubit in a semiconductor quantum dot preserves the measured spin and allows for exponential suppression of readout errors by repeated measurements.
