TL;DR: Cd(II) is chosen as a model of a small molecule with less sites, and a novel SELEX strategy of immobilizing ssDNA libraries rather than target molecules on a matrix is proposed, for selection of aptamers with high affinity to Cd( II).

TL;DR: In this review, four types of the FNAs that most widely-used in heavy metal ions detection were briefly introduced and a dozen of recently published review articles which summarized those FNAs-based sensors were introduced.

TL;DR: In this paper , the authors describe advances in the application of nanomaterials in chemical pesticides and fertilizers, which are the two earliest and most researched areas of NMs in agrochemicals.

TL;DR: This colorimetric method was exploited to detect bisphenol A based on BPA-specific aptamer and cationic polymer-induced aggregation of gold nanoparticles (AuNPs) and was successfully used to determine spiked BPA in tap water and river water samples.

TL;DR: In this article, the catalytic activity of higher concentration of hemin can be temporarily inhibited by arsenic-binding aptamers, and it will recover in the presence of As(III) due to the exhaustion of aptammers, so the subsequent TMB molecules can be oxidized thoroughly and cause a remarkable increase of absorbance value at 442 nm.
