What is the term for a material that contains nanoparticles or is created using nanotechnology?

The term that refers to a material containing nanoparticles or created using nanotechnology is "nanomaterial." Nanomaterials are defined by their unique properties arising from their nanoscale dimensions, often resulting in enhanced mechanical, electrical, optical, or chemical characteristics compared to their bulk counterparts. The manipulation and integration of materials at the nanoscale are fundamental principles of nanotechnology, which allows for innovations in various fields such as medicine, electronics, and materials science.

Other options do not encompass the broader definition of materials created with nanotechnology. For instance, nanocellulose specifically refers to a cellulose-derived nanomaterial, while nanocomposites involve a matrix material that is reinforced with nanoparticles but doesn’t represent all materials created with nanotechnology. Nanosensors are devices specifically designed to detect and measure nanoscale materials or phenomena, which is a more specialized application rather than a definition of a material itself. Therefore, "nanomaterial" is the most inclusive and accurate term to describe materials that contain nanoparticles or are synthesized through nanotechnology.
