Nutrient delivery in nanotechnology refers to the use of nanoscale materials and systems to improve the delivery and efficacy of nutrients. This can involve the encapsulation, targeted delivery, and controlled release of nutrients in a highly efficient manner. By leveraging the unique properties of nanomaterials, such as their small size, large surface area, and ability to interact with biological systems at the molecular level, nanotechnology offers promising solutions for enhancing nutrient absorption and bioavailability.
