👉 Necklace engineering is an innovative approach in materials science and nanotechnology that involves the design, synthesis, and manipulation of metallic and non-metallic nanoparticles to create intricate, wearable structures resembling traditional jewelry necklaces. This process leverages the unique properties of nanoparticles, such as their high surface area-to-volume ratio and quantum effects, to produce materials with enhanced mechanical, optical, and electronic properties. Engineers can precisely control the size, shape, and composition of these nanoparticles to tailor the necklaces for specific applications, such as sensors, energy storage devices, or even biomedical devices. The flexibility and customizability of necklace engineering make it a promising field for developing next-generation smart textiles and multifunctional wearable technologies.
