Which term describes a material made from two or more types of particles, including at least one nanoparticle?

The term that accurately describes a material composed of two or more types of particles, with at least one being a nanoparticle, is nanocomposite. Nanocomposites integrate nanoparticles into a matrix of other material to enhance various properties such as strength, thermal stability, and electrical conductivity. This combination allows for tailored material characteristics that are not present in the individual components.

Nanocellulose refers specifically to a form of cellulose that has been processed to the nanoscale, but it does not inherently imply the presence of multiple types of particles. Nanosensors are devices that utilize nanomaterials to detect or measure specific substances or changes in the environment. Meanwhile, a nanoparticle is simply a small particle with dimensions on the nanoscale, but it does not denote a composite or mixture of different particle types. Thus, while all these terms relate to nanotechnology, nanocomposite is the one that specifically pertains to the concept of integrating multiple particle types, including nanoparticles.
