What term describes the process of assembling products by building single atoms and molecules into larger nanostructures?

The process of assembling products by building single atoms and molecules into larger nanostructures is known as bottom-up assembly. This approach involves starting with the smallest units, such as atoms and molecules, and progressively constructing larger and more complex structures.

Bottom-up assembly is fundamental in nanotechnology because it allows for high precision and control at the molecular level, leading to innovative materials and devices with desired properties. This method contrasts with the top-down assembly approach, which starts with larger materials and manipulates them into smaller components, often resulting in limitations regarding the precision of scaling down features.

The perspective of bottom-up assembly highlights the advantages of using self-assembly techniques, where components can spontaneously organize into structured arrangements, potentially reducing costs and resource use in the manufacturing process.
