摘要

DNA interactions with multivalent cations, leading to wrapping around the cations and thermodynamically stable structure formation, followed by electrodeposition, have yielded a narrow size distributed single-crystalline HgTe-DNA quantum dot (QD) hybrid system. The mechanisms of the DNA interactions resulting in self-assembled HgTe QDs through phosphate-cation linkages and superstructure formation by nitrogen base interactions have been established by their respective binding energy shifts as evidenced from x-ray photoelectron spectroscopic studies. The photoluminescence peak position associated with HgTe QD single stranded DNA is red shifted in the presence of its conjugate and suggests the system as a potential optical probe for biomolecular recognition applications.
