Toward combining graphene and QDs: assembling CdTe QDs to exfoliated graphite and nanographene in water.

Herein, we report for the first time on a full-fledged investigation of water-soluble CdTe quantum dots (QD) that are immobilized onto exfoliated graphite (EG) and/or nanographene (NG). Particular emphasis was placed on a top-down preparation of stable aqueous dispersions-starting from natural graphite rather than graphene oxide-while preserving the intrinsic properties of graphene. To this end, we circumvented the harsh conditions commonly employed for the pre-exfoliation (i.

Conjugating luminescent CdTe quantum dots with biomolecules.

Newly prepared CdTe quantum dots ( QD) bearing shells of water solubility providing capping agents (i.e., thioglycolic acid ( TGA) and 2-(dimethylamino)ethanethiol hydrochloride (DMAET) were subjected to electrostatic assays with several proteins (i.

Synthesis and characterization of positively capped CdTe quantum wires that exhibit strong luminescence in aqueous media.

The novelty of the current work lies in the versatile synthesis of highly luminescent water-soluble CdTe quantum rods (QR) which to the best of our knowledge are the first known water-soluble QR carrying positively charged stabilizer.
