TL;DR: An electrochemical RNA aptamer-based biosensor for rapid and label-free detection of the bronchodilator theophylline was developed and it was demonstrated that theophylla is detected with high selectivity in the presence of caffeine and theobromine.

TL;DR: The proposed design of the aptasensor, based on electrostatic interactions between the positively charged cysteamine-modified electrode and the negatively charged aptamer, may be used as a general strategy not to restrict the conformational freedom and binding properties of surface-bound aptamers and, thus, be applicable for the development of other aptasensors.

TL;DR: In this article, the photoelectrocatalytic activity of the hematite electrodes modified with Ti4+ and Zn2+ was optimized through the controlled variation of the dopant ion concentration in the electrodeposition solution.

TL;DR: Only gold electrodes with adsorbed recombinant HRP forms exhibited high and stable current response to H( 2)O(2) due to its bioelectrocatalytic reduction based on direct electron transfer between gold and HRP, giving strong evidence that the electrode currents are diffusion limited.

TL;DR: A simple and robust "off-on" signaling genosensor platform with improved selectivity for single-nucleotide polymorphism (SNP) detection based on the electronic DNA hairpin molecular beacons has been developed.
