Nanotechnology has found various applications in the development of smartphones and computers, contributing to advancements in performance, durability, and functionality. Some key components that incorporate nanotechnology in these devices include:

1. Semiconductor Technology: Nanoscale components are crucial in the manufacturing of semiconductor devices, such as transistors and memory cells. The use of nanomaterials and nanoscale structures enhances the efficiency and speed of these components, leading to faster and more energy-efficient devices.

2. Nanocomposites for Structural Components: Nanocomposites, which are materials with nanoparticles dispersed in a matrix, are used in the construction of various structural components in smartphones and computers. These materials can provide improved strength, durability, and reduced weight.

3. Nanoelectronics: Nanotechnology is applied in the design and fabrication of nanoscale electronic components. This includes the development of nanoscale transistors and other electronic devices that enable the miniaturization of electronic circuits, leading to smaller and more powerful devices.

4. Nanocoatings: Nanotechnology is employed in the production of nanocoatings for various components, such as screens and casings. These coatings can provide scratch resistance, water repellency, and other protective features to enhance the durability and longevity of the devices.

5. Nanostructured Batteries: Nanotechnology is utilized in the development of advanced battery technologies. Nanostructured materials can improve the performance of batteries, offering higher energy density, faster charging times, and longer lifespan. This is particularly relevant in smartphones and laptops where battery life is a critical factor. Many companies have R&D divisions dedicated to the advancement of battery technology through nanoscience. Many companies have tested nanotechnology on their smartphone batteries, and Samsung has tested it on the Galaxy S7. By coating the electrons with nanoparticles or nanowires, the anodes that hold the lithium ions get a boost to their power density, as nanoparticles weigh nearly nothing but create more area in which power can be stored. In fact some scientists from the Georgia Institute of Technology think you might someday charge your phone while you walk, jog or do some other physical activity by way of nanotechnology.

6. Quantum Dots for Displays: Quantum dots, nanoscale semiconductor particles, are used in display technologies to enhance color accuracy and brightness. Quantum dot displays offer improved performance compared to traditional LED displays in terms of color reproduction and energy efficiency.The University of Cambridge (UK) and Nokia Research Center (NRC), developed Nokia Morph, a joint nanotechnology concept that shows how the mobile devices of the future can be flexible and stretchable, thus enabling the user to convert their mobiles and devices into radically different shapes. All of this shows the significant role that nanotechnology can deliver; including self-cleaning surfaces,
   

7. Nanophotonics: Nanotechnology plays a role in the field of nanophotonics, which involves the manipulation of light at the nanoscale. This is important for the development of smaller and more efficient optical components used in communication devices and sensors.

8. Nanomechanical Systems: Nanoscale mechanical systems, such as nanoelectromechanical systems (NEMS), can be integrated into devices for sensing and actuation. These tiny mechanical components contribute to the development of advanced sensors and actuators in smartphones and computers.

Overall, the integration of nanotechnology in smartphones and computers is a multidisciplinary approach, involving materials science, electronics, and engineering, to enhance the performance, functionality, and durability of these devices.
