Abstract

CdS/ZnS core shell quantum dots (QDs) were synthesized and functionalized by methionine and characterized by standard techniques. The prior QD-based phytotoxicity assay was helpful to find out the maximum tolerant level of the plant cells. The successful transport and phytotoxic mechanism of QDs were elaborated in detail. Methionine functionalities on the QDs were helpful in specific binding of QDs with the nucleus of stomata in plant cells. Target specific interaction with the nucleus of stomata cells was a novel breakthrough that can be used in many biologic applications.
