A rapid signal amplification system based on the self-replicating catalyzed hairpin assembly is reported in which two hairpins, H1 and H2, were well-designed split target/trigger DNA G-quadruplex sequences respectively integrated into H2. Target/trigger can be cyclically used this to form duplex assemblies (H1–H2), will bring fragments close-enough proximity induce formation of intact as a colorimetric readout. Similarly, reunite sequence that identical DNA; then, obtained replica also new...

Specific and sensitive detection imaging of cancer-related miRNA in living cells are desirable for cancer diagnosis treatment. Because the spatiotemporal variability expression level during different cell cycles, signal amplification strategies that can be activated by external stimuli required to image miRNAs on demand at desired times selected locations. Herein, we develop a strategy termed as photoactivated DNA walker based nanoflares, which enables photocontrollable single cells. The...

Abstract Cytochrome c (Cyt. ) is a key initiator of the caspases that activate cell apoptosis. The spatiotemporal evaluation contents Cyt. in cellular compartments and detection delivery between upon apoptosis important for probing viabilities. We introduce an optical probe electrochemical quantitative assessment at single level. or probes are functionalized with photoresponsive o‐nitrobenzylphosphate ester‐caged aptamer constituents. These uncaged by light stimuli compartments, allowing...

It is known that the adsorption of short single-stranded DNA (ssDNA) on unmodified gold nanoparticles (AuNPs) much faster than for long ssDNA, and thus leads to length-dependent AuNPs aggregation after addition salt, color solutions sequentially changed from red blue in accordance with increase ssDNA length. However, we found herein sticky end hairpin exhibited a completely different behavior compared an inverse blue-to-red variation was observed colloid solution length when within certain...

Abstract Increasing use of ion-selective electrodes (ISEs) in the biological and environmental fields has generated demand for high-sensitivity ISEs. However, improving sensitivities ISEs remains a challenge because limit Nernstian slope (59.2/n mV).
