A cytosine-rich hairpin DNA loaded with silver nanoclusters as a fluorescent probe for uranium(IV) and mercury(II) ions

NH3 Plasma Functionalization of UiO-66-NH2 for Highly Enhanced Selective Fluorescence Detection of U(VI) in Water

“…To date, the techniques developed for detecting U­(VI) mainly include radiometric methods, resonance Rayleigh scattering, , X-ray fluorescence spectrometry, atomic spectroscopy, electrochemical detection, fluorescence probe, , and laser Raman spectroscopy . Among them, fluorescence probes have been an important approach for U­(VI) detection and have attracted increasing attention due to their simplicity of implementation and good sensitivity, stability, and selectivity properties. , …”

DNA-Hairpin-Templated Silver Nanoclusters: A Study on Stem Sequence

“…A deliberately designed DNA hairpin (H0, Table S1) with even content of four kinds of bases was used as the object to study synthesis conditions. This hairpin DNA H0 contains a 6-C loop, because the 6-C loop was most frequently used in previous works 36 and was reported to bring the brightest hairpin-AgNCs. 32 H0 contains a stem of 20 base pairs, a reasonable enough length for studying the content ratio and base distribution but not overlong for an economical consideration.…”

A self-cascade system based on Ag nanoparticle/single-walled carbon nanotube nanocomposites as an enzyme mimic for ultrasensitive detection of l-cysteine

“…DNA-AgNCs was prepared using the protocol mentioned by our group. 32 Briefly, DNA was first dissolved in DEPC water (treated with diethyl pyrocarbonate and autoclaved at high temperature and pressure). Then, 400 μL of buffer (NH 4 Ac–HAc, pH 6.8), 190 μL of ultrapure water and AgNO 3 (140 μL, 1 mM) were added, and the mixture solution was incubated at 4 °C for 30 min.…”
