Structural effects and nanoparticle size are essential for quantum dots-metallothionein complex formation

Popis výsledku v původním jazyce

Interaction between semiconductor nanocrystals, cadmium telluride quantum dots (CdTe QDs) capped with mercaptosuccinic acid (MSA) and metallothionein (MT) was investigated. MSA-capped CdTe QDs were synthesized in aqueous solution. Mixture of MT and MSA-capped CdTe QDs has been investigated by various analytical methods as follows: tris-tricine gel electrophoresis, fluorescence evaluation and electrochemical detection of catalysed hydrogen evolution. The obtained results demonstrate that MSA-capped CdTeQDs and MT do not create firmly bound stabile complex. However, weak electrostatic interactions contributes the interaction of MT with MSA-capped CdTeQDs.. It can be concluded that QDs size influences QDs and MT interaction. The smallest QDs had the highest affinity to MT and vice versa.
