Researchers Find Degradation of Quantum Dots Can Release Toxic Ions

Description Quantum dots manufactured from selenium and cadmium can decompose in soil and release harmful selenium and cadmium ions into the environment, according to researchers at the University of Buffalo. Data also proved under normal conditions, quantum dots in top soil will not navigate into underground water tables without presence of chelating agents such as naturally-occurring organic acids.

Further researcher found while quantum dots can also biodegrade, which is a negative finding, it is also possible to alter the surface of the nanomaterials and chemistry and to avoid future degradation.
