TL;DR: In this paper, a signaling-probe displacement electrochemical aptamer-based sensor (SD-EAB) was proposed, in which signal transduction is induced only by the affinity binding between an aptamer and its target and completely independent of the conformational state of the aptamer.

TL;DR: In this paper, the authors proposed a signaling-probe displacement electrochemical aptasensor (SD-EAS) that achieved excellent performance for the detection of kanamycin A, but failed the detections of lipophilic antibiotics including ampicillin (Ampi) and sulfadimethoxine (SDM).

TL;DR: For the first time, group-specific PAE-binding aptamers via rationally designed target immobilization are identified and offered the promise of convenient, low-cost detection of total PAEs.

TL;DR: In this article, a DNA aptamer of a phthalate type plasticizer and a screening and expression method and an electro-chemical sensor thereof are presented. But the detection of phthalates in foods or environments is not discussed.

TL;DR: In this paper , a simple and reliable approach for the ultra-sensitive detection of miRNA by integrating endonuclease-III (Exo-III) assisted signal recycle, primer exchange reaction (PER), and hairpin catalytic reaction (HCR) was proposed.
