Abstract
Drawing upon an intramolecular cyclization/annulation reaction sequence mediated by Hg 2+ ions, a BODIPY-based fluorescent probe decorated with an alkynyl hydrazone motif responds rapidly and selectively to Hg 2+ ions, with a detection limit of 29 nM and a fluorescence turn-on ratio of 15-fold. With the addition of Hg 2+ ions, the BODIPY-based alkynyl hydrazone transforms into a pyrazole ring to mediate a turn-on emission response clearly observable to the naked eye under visible light excitation.

Abstract
Mercury ion (Hg2+) is a heavy metal that can cause serious water pollution. With the accumulation of large quantities in lakes, rivers, freshwater and aquatic life, Hg2+ can pass through the food chain, entering the human body and endangering health. Hg2+ detection has therefore become important thereby attracting extensive interests. Currently, several DNA-based sensors have been used for Hg2+ detection because they are not easy to degrade and are very stable. This paper summarizes the application of some DNA-based sensors based on fluorescence resonance energy transfer (FRET), analyzes their characteristic, and compares their sensitivity. Future perspectives and possible challenges in this area are also outlined.

Abstract
Mercury (II) ion (Hg(2+)) contamination can be accumulated along the food chain and cause serious threat to the public health. Plenty of research effort thus has been devoted to the development of fast, sensitive and selective biosensors for monitoring Hg(2+). Thymine was demonstrated to specifically combine with Hg(2+) and form a thymine-Hg(2+)-thymine (T-Hg(2+)-T) structure, with binding constant even higher than T-A Watson-Crick pair in DNA duplex. Recently, various novel Hg(2+) biosensors have been developed based on T-rich Mercury-Specific Oligonucleotide (MSO) probes, and exhibited advanced selectivity and excellent sensitivity for Hg(2+) detection. In this review, we explained recent development of MSO-based Hg(2+) biosensors mainly in 3 groups: fluorescent biosensors, colorimetric biosensors and electrochemical biosensors.

Abstract
By intelligent design, a new "turn-on" fluorescent probe (1-CN) was obtained based on the deprotection reaction of the dithioacetal promoted by Hg2+ ions, which could sense mercury ions sensitively and selectively, with the detection limit of 8×10(-7) M. Thanks to the apparent turn-on signal, 1-CN has been successfully applied to rapidly detect trace amounts of mercury ions as test strips and cell image.

Abstract
Carbamodithioate-based compound T1 was designed and synthesized as a dual-functional probe for Hg(2+) ions and S(2-) anions. The underlying signaling mechanism was intramolecular charge transfer (ICT). It could serve as a direct probe towards Hg(2+) ions through "on-off" fluorescence changes and an indirect probe towards S(2-) anions through "on-off-on" fluorescence changes.

Abstract
We report a label-free fluorescence turn-on approach for the sensitive and selective sensing of silver ion Ag(+) based on Ag(+) induced conformational change of cytosine-rich single-stranded DNA. A silver specific oligonucleotide (SSO) undergoes a structural transition from single-stranded DNA (ssDNA) to a C-Ag(+)-C mediated hairpin structure, which can be recognized by a double-stranded DNA (dsDNA) intercalator Sybr Green I (SG). The linear response range for Ag(+) detection was from 1 nM to 100 nM. The method presented here is highly sensitive and a limit of detection of 1 nM was obtained. More importantly, this optical method was successfully used to identify complex sample mixtures.

Abstract
Miniaturization is currently an important trend in environmental and food monitoring because it holds great promise for on-site monitoring and detection. We report here two ready-to-use chip-based fluorescent sensors, compatible with microarray technology for reagentless, one-step, fast, highly sensitive and selective detection of the mercuric ion (Hg(2+)) in the turn-on and turn-off operation modes. Both operation modes are based on the highly selective T-Hg(2+)-T coordination between two neighboring polythymine (T) strands at a high probe density and its induced displacement of the complementary polyadenine strand labeled with either fluorophore or quencher, which enables the turn-off and turn-on detection of Hg(2+), respectively. The turn-off sensor is slightly more sensitive than the turn-on sensor, and their detection limits are 3.6 and 8.6 nM, respectively, which are both lower than the U.S. Environmental Protection Agency limit of [Hg(2+)] for drinkable water (10 nM, 2 ppb). Compared to the turn-off sensor with the dynamic Hg(2+) detection range from 3.6 nM to 10 μM (R(2) = 0.99), the turn-on sensor has a broader dynamic Hg(2+) detection range, from 8.6 nM to 100 μM (R(2) = 0.996). Both sensors exhibited superior selectivity over other reported sensors using thymine-rich probes for Hg(2+) detection over other common metal ions. In addition, the practical application of the chip-based sensors was demonstrated by detecting spiked Hg(2+) in drinking water and fresh milk. The sensor has great potential for on-site practical applications due to its operational convenience, simplicity, speed, and portability.

Abstract
Two new brush polyoxyethylenes bearing thymine moieties at the bristle ends have been synthesized as model polymers in which the chemical loading of the thymine functional group into the polymer is maximized: poly(oxy(11-thyminoacetyloxyundecylthiomethyl)ethylene) (PECH(S)-T) and poly(oxy(11-thyminoacetyloxyundecylsulfonylmethyl)ethylene) (PECH(SO(2))-T). These brush polymers are thermally stable up to around 225 °C, and their glass transitions occur in the range 23-27 °C, but they have significantly different properties despite the similarity of their chemical structures. In particular, PECH(SO(2))-T films exhibit better performance in sensing mercury ions than PECH(S)-T films. These differences were found to originate in the differences between their morphological structures. The PECH(SO(2))-T film has a multi-bilayer structure without interdigitation, in which the layers stack along the out-of-plane of the film and provide a thymine-rich surface. In contrast, the PECH(S)-T film is amorphous with a relatively low population of thymine moieties at the surface. This study demonstrated that a thymine-rich surface is required for recyclable thymine-based polymers to provide highly improved sensitivity and selectivity as well as full reversibility in the sensing of mercury ions. A thymine-rich surface can be achieved with a brush polymer bearing thymine moieties that can self-assemble into a multi-bilayer structure. Because of the thymine-rich surface, the PECH(SO(2))-T thin films even in only 6 nm thickness demonstrate the detection of mercury ions in aqueous solutions with a detection limit of 10(-6) M.

Abstract
Two chromogenic complexes, L.Zn (where L is (E)-4-((4-(1,4,8,11-tetraazacyclotetradecan-1-ylsulfonyl)phenyl)diazenyl)-N,N-dimethylaniline) and its [2]pseudorotaxane form (α-CD.L.Zn), were found to bind preferentially to adenosine triphosphate (ATP), among all other common anions and biologically important phosphate (AMP, ADP, pyrophosphate, and phosphate) ions in aqueous HEPES buffer medium of pH 7.2. Studies with live cell cultures of prokaryotic microbes revealed that binding of these two reagents to intercellular ATP, produced in situ, could be used in delineating the gram-positive and the gram-negative bacteria. More importantly, these dyes were found to be nontoxic to living microbes (eukaryotes and prokaryotes) and could be used for studying the cell growth dynamics. Binding to these two viable staining agents to intercellular ATP was also confirmed by spectroscopic studies on cell growth in the presence of different respiratory inhibitors that influence the intercellular ATP generation.

Abstract
Mercury is a highly hazardous and widespread pollutant with bioaccumulative properties. Novel approaches that meet the criteria of desired selectivity, high sensitivity, good biocompatibility, and low background interference in natural settings are continuously being explored. We herein describe a new strategy utilizing the combination of infrared fluorescent protein (IFP) and its chromophore as an infrared fluorescence probe for mercury ion (Hg(II)) detection. Hg(II) has been validated to have specific binding affinity to a cysteine residue (C24) of IFP, thereby inhibiting the conjugation of IFP chromophore biliverdin (BV) to C24 and "turning off" the infrared emission of IFP. The IFP/BV sensor has high selectivity toward Hg(II) among other metal ions over a broad pH range. The in vitro detection limit was determined to be less than 50 nM. As a genetically encoded probe, we demonstrate the IFP/BV sensor can serve as a tool to detect Hg(II) in living organisms or tissues. Moreover, we have exploited a protein-agarose hydrogel-based paper assay to immobilize IFP for detection of Hg(II) in a portable and robust fashion.

Abstract
Metal ion sensors are an important yet challenging field in analytical chemistry. Despite much effort, only a limited number of metal ion sensors are available for practical use because sensor design is often a trial-and-error-dependent process. DNAzyme-based sensors, in contrast, can be developed through a systematic selection that is generalizable for a wide range of metal ions. Here, we summarize recent progress in the design of DNAzyme-based fluorescent, colorimetric, and electrochemical sensors for metal ions, such as Pb(2+), Cu(2+), Hg(2+), and UO(2)(2+). In addition, we also describe metal ion sensors based on related DNA molecules, including T-T or C-C mismatches and G-quadruplexes.
