The document discusses the potential for using low-cost nanostructures for sensing applications in an increasingly connected world. It presents examples of low-cost zinc oxide and nickel-nickel oxide nanostructures that have been used to create light diffusers, UV detectors, pH and gas sensors, cancer detectors, and glucose sensors. These types of low-cost nanostructures could enable applications like UV detection, glucose monitoring, food allergen detection, and more. The document emphasizes that these nanostructures can be fabricated using flexible and inexpensive methods like solution synthesis, thermal processing, and printing.
