A company is developing a medical test. Particles of a material are added to a sample, and a signal is produced when the particles interact with a substance in the sample.
The company tested particles of the same material with two different particle sizes. The same sample and the same conditions were used in each test.
| Type of particles | Mass of particles added in g | Signal produced in arbitrary units |
|---|---|---|
| Larger particles | 0.40 | 80 |
| Nanoparticles | 0.08 | 80 |
Explain how the results show an advantage of using the nanoparticles in this test.
