Fluorometric detection of silver(I) using cytosine-Ag(I)-cytosine pair formation, DNA assembly and the AND logic operation of a multiple-component DNAzyme

A review on silver-mediated DNA base pairs: methodology and application

“…In the same year, Xu [ 34 ] used the principle of combining catalytic core sequences (partzymes) to form a multi-component nuclease (MNAzyme), and designed a three-way junction nano-signal (3-WJ) to detect Ag + . The basic principle is shown in the Fig.…”

Thermodynamic stability of cytosine tetramers mediated by partially reduced silver trimers: QM/MM free energy analysis

“…Incorporating tightly bound silver cations into DNA promises more robust, diversely functional DNA‐based functional materials [1]. Self‐assembled silver‐mediated base pairs are versatile building blocks, allowing flexible design for nanoelectronics [2–4], biosensors [5], nanowires [6], nanointerfaces [7], and so forth. Significant efforts have been made to enlighten the spatial ordering of silver‐mediated complexes by means of structural X‐ray experiments, which made it possible to obtain uninterrupted silver ion arrays [8, 9].…”

Unexpected cytosine–AuCl4− interaction under electrospray ionization mass spectrometry conditions—Formation of cytosine–Au(I) complexes

“…[11][12][13][14] Formation of this stable complex has allowed the design of a number of analytical methods for Ag þ determination. [15][16][17][18][19][20] Detailed structural studies of cytosine-Ag þ complexes have also been reported. 21,22 The interaction of cytosine tautomers with the nanoparticle of all group 11 elements has been analyzed in details.…”
