As surface area per volume increases, materials can become more reactive. The extinction spectra of 15 sizes of NanoXact Gold nanoparticles at identical mass concentrations (0.02 mg/mL) are displayed in the figure below. What are the parameters which change when your bulk material is converted into nanomaterials? Moreover, examples of these materials include nanozymes, titanium dioxide nanoparticles, graphene, etc. This is because nanoparticles are smaller and can absorb greater amount of solar radiation. Some nanoparticles such as gold nanoparticles also have the advantage of melting at much lower temperatures (~300 C for 2.5 nm size) than their bulkier counterparts (gold slabs melt at ~ 1064 C).

Nanoparticle - Wikipedia Some properties of nanoparticulate materials are different from the properties of the same material in bulk, as powders, lumps or sheets. Why do nanoparticles have different properties from those for the same materials in bulk? This is because of the high surface area to volume ratio. 1972 Pontiac Lemans Endura, For example, nanoparticles of sizes about 90 nm absorb red to yellow light and emit blue-green, whereas particles around 30 nm in size absorb blue and green light and appear red in color. Engineered nanoparticles play an important role in nanotechnology. While this diffusion property exhibited by nanoparticles may not affect the density of the product, it can lead to agglomeration.
