Formation of Silver Nanoclusters from a DNA Template Containing Ag(I)-Mediated Base Pairs.
نویسندگان
چکیده
A series of DNA double helices containing different numbers of silver(I)-mediated base pairs involving the artificial nucleobases imidazole or 2-methylimidazole has been applied for the generation of DNA-templated silver nanoclusters. The original Ag(I)-containing nucleic acids as well as the resulting nanoclusters and nanoparticles have been characterized by means of UV/Vis spectroscopy, circular dichroism (CD) spectroscopy, fluorescence spectroscopy, and transmission electron microscopy (TEM). The results show for the first time that metal-mediated base pairs can be used for the templated growth of metal nanoclusters.

متن کاملCooperative formation of silver(I)-mediated base pairs.
DNA double helices comprising two neighbouring artificial imidazole-Ag(I)-imidazole base pairs incorporate the Ag(I) ions in a cooperative fashion. Isothermal titration calorimetry data confirm the theoretically predicted binding stoichiometry and indicate that Ag(I) binds with association constants >10(6) M(-1) to the metal-free DNA duplex.

Unmodified single-stranded DNA has recently gained popularity for the templated synthesis of fluorescent noble metal nanoclusters (NCs). Bright, stable, and biocompatible clusters have been developed primarily through optimization of DNA sequence. However, DNA backbone modifications have not yet been investigated. In this work, phosphorothioate (PS) DNAs are evaluated in the synthesis of Au and...
متن کاملTarget-controlled formation of silver nanoclusters in abasic site-incorporated duplex DNA for label-free fluorescence detection of theophylline.
A novel, label-free, fluorescence based sensor for theophylline has been developed. In the new sensor system, an abasic site-incorporated duplex DNA probe serves as both a pocket for recognition of theophylline and a template for the preparation of fluorescent silver nanoclusters. The strategy relies on theophylline-controlled formation of fluorescent silver nanoclusters from abasic site-incorp...
متن کاملSilver(I)-mediated Hoogsteen-type base pairs.
Metal-mediated Hoogsteen-type base pairs are useful for the construction of DNA duplexes containing contiguous stretches of metal ions along the helical axis. To fine-tune the stability of such base pairs and the selectivity toward different metal ions, the availability of a selection of artificial nucleobases is highly desirable. In this study, we follow a theoretical approach utilizing disper...
