“…By using nanoparticles to distribute nutrients [ 116 , [118] , [119] , [120] ] directly to plant roots and nanosensors to detect nutrient deficits in soil, new agricultural technologies [ [87] , [88] , [89] , [90] , [121] , [122] , [123] , [124] ] can be created to boost crop yields and decrease waste (Goal 15). Furthermore, by incorporating silver, titanium dioxide, silver, gold, copper, and cadmium sulfide nanoparticles into packaging materials to provide a barrier against oxygen and moisture, nanotechnology can be used to build novel food packaging [ [125] , [126] , [127] , [128] , [129] ] materials that prolong food's shelf life and lower spoilage. Also, by using nanosensors to continuously monitor soil moisture levels, new water management technologies can be created that increase irrigation effectiveness and decrease water waste.…”
