TL;DR: A dual DNA tweezers nanomachine was developed for one-step simultaneous detection of aflatoxin B1 (AFB1) and ochratoxin A (OTA) in food samples and the applicability of the method was further demonstrated by conducting a limited survey on 5 samples collected from various sources.

TL;DR: A novel fluorescent detection strategy based on DNAzyme branched junction structure with three kinds of DNAzymes and graphene oxide that was successfully used for simultaneous detection of Cu2+, Mg2+ and Pb2+ in human serum and had potential application for simultaneous Detection of multiple metal ions in environmental and biological samples.

TL;DR: An enzyme-free amplification fluorescent strategy for ultra-sensitive detection of Hg2+ based on graphene oxide (GO) and catalytic hairpins self-assembly was reported in this paper.

TL;DR: In this paper, the enzyme-strand recycling and hairpin catalytic assembly (HCA) reaction were used as dual enzyme-free amplification strategies for detection of uranyl in river waters samples.

TL;DR: An ultra-sensitive strategy for bisphenol A (BPA) detection based on dual enzyme-free strategies: hybridization chain reaction (HCR) and enzyme-strand recycling reaction has been developed, showing a promising future for on-site detection of BPA in practical application.
