Size-specific imprinted polymer embedded carbon nanodots modified magnetic nanoparticle for specific recognition of titanium nanoparticle: The round versus round.

Like the two sides of a coin, any new invention or discovery also possess their two faces. Similarly, while nanomaterials were identified as a boon in several fields like industrial, medicinal or agriculture; some of them have been also validated as a risk to the environment and living organisms. In this report, we addressed an efficient optical method for the detection of popularly used titanium dioxide nanoparticle (TiO2) by a size-specific imprinted polymer embedded heteroatom-doped carbon nanodots (CNDs) decorated at the surface of the water-soluble magnetic nanoparticle.
