Tunable, colorimetric DNA-based pH sensors mediated by A-motif formation.
نویسندگان
چکیده
A colorimetric pH sensor has been developed based on GNP aggregation mediated by A-motif formation under acidic conditions. The pH response of the sensor can be tuned in the range of pH 2-5.5 by changing the length and the sequence of the A-motif forming poly dA tracts.

متن کاملPhotonic Crystal Structures with Tunable Structure Color as Colorimetric Sensors
Colorimetric sensing, which transduces environmental changes into visible color changes, provides a simple yet powerful detection mechanism that is well-suited to the development of low-cost and low-power sensors. A new approach in colorimetric sensing exploits the structural color of photonic crystals (PCs) to create environmentally-influenced color-changeable materials. PCs are composed of pe...
متن کاملStructures of the kinetically trapped i-motif DNA intermediates.
In the present work, the conformational dynamics and folding pathways of i-motif DNA were studied in solution and in the gas-phase as a function of the solution pH conditions using circular dichroism (CD), photoacoustic calorimetry analysis (PAC), trapped ion mobility spectrometry-mass spectrometry (TIMS-MS), and molecular dynamics (MD). Solution studies showed at thermodynamic equilibrium the ...
متن کاملNanomechanical DNA Origami pH Sensors
Single-molecule pH sensors have been developed by utilizing molecular imaging of pH-responsive shape transition of nanomechanical DNA origami devices with atomic force microscopy (AFM). Short DNA fragments that can form i-motifs were introduced to nanomechanical DNA origami devices with pliers-like shape (DNA Origami Pliers), which consist of two levers of 170-nm long and 20-nm wide connected a...
متن کاملPoly(L-lysine)-graft-dextran copolymer promotes pyrimidine motif triplex DNA formation at physiological pH. Thermodynamic and kinetic studies.
Extreme instability of pyrimidine motif triplex DNA at physiological pH severely limits its use for artificial control of gene expression in vivo. Stabilization of the pyrimidine motif triplex at physiological pH is therefore of great importance in improving its therapeutic potential. To this end, isothermal titration calorimetry interaction analysis system and electrophoretic mobility shift as...
