Abstract
DNAzyme-based fluorescent probes for imaging metal ions in living cells have received much attention recently. However, employing in situ metal ions imaging within subcellular organelles, such as nucleus, remains a significant challenge. We developed a three-stranded DNAzyme probe (TSDP) that contained a 20-base-pair (20-bp) recognition site of a CRISPR/Cas9, which blocks the DNAzyme activity. When Cas9, with its specialized nuclear localization function, forms an active complex with sgRNA within the cell nucleus, it cleaves the TSDP at the recognition site, resulting in the in situ formation of catalytic DNAzyme structure. With this design, the CRISPR/Cas9-inducible imaging of nuclear Zn2+ is demonstrated in living cells. Moreover, the superiority of CRISPR-DNAzyme for spatiotemporal control imaging was demonstrated by integrating it with photoactivation strategy and Boolean logic gate for dynamic monitoring nuclear Zn2+ in both HeLa cells and mice. Collectively, this conceptual design expands the DNAzyme toolbox for visualizing nuclear metal ions and thus provides new analytical methods for nuclear metal-associated biology.

Abstract
Here, we describe the design and synthesis of a new reduction-cleavable spacer (RCS) based on a nitrobenzene scaffold for constructing reduction-responsive oligonucleotides according to standard phosphoramidite chemistry. In addition, we demonstrate that the introduction of the RCS in the middle of an oligonucleotide (30 nt) enables the construction of a self-assembled microsphere capable of exhibiting a reduction-responsive disassembly.

Abstract
DNAzymes are functional nucleic acid with catalytic activity. Owing to the high sensitivity, excellent programmability, and flexible obtainment through in vitro selection, RNA-cleaving DNAzymes have attracted increasing interest in developing DNAzyme-based sensors. In this review, we summarize the recent advances on DNAzyme-based sensing applications. We initially conclude two general strategies to expand the library of DNAzymes, in vitro selection to discover new DNAzymes towards different targets of interest and chemical modifications to endue the existing DNAzymes with new function or properties. We then discuss the recent applications of DNAzyme-based sensors for the detection of a variety of important biomolecules both in vitro and in vivo . Finally, perspectives on the challenges and future directions in the development of DNAzyme-based sensors are provided.

Abstract
Direct measurement of DNA repair is critical for the annotation of their clinical relevance and the discovery of drugs for cancer therapy. Here we reported a "repaired and activated" DNAzyme (RADzyme) by incorporating a single methyl lesion (O6 MeG, 3MeC, or 1MeA) at designated positions through systematic screening. We found that the catalytic activity of the RADzyme was remarkably suppressed and could be restored via enzyme-mediated DNA repair. Benefit from these findings, a fluorogenic RADzyme sensor was developed for the monitoring of MGMT-mediated repair of O6 MeG lesion. Importantly, the sensor allowed the evaluation of MGMT repair activity in different cells and under drugs treatment. Furthermore, another RADzyme sensor was engineered for the monitoring of ALKBH2-mediated repair of 3MeC lesion. This strategy provides a simple and versatile tool for the study of the basic biology of DNA repair, clinical diagnosis and therapeutic assessment.

Abstract
Bioorthogonal control of metal-ion sensors for imaging metal ions in living cells is important for understanding the distribution and fluctuation of metal ions. Reported here is the endogenous and bioorthogonal activation of a DNAzyme fluorescent sensor containing an 18-base pair recognition site of a homing endonuclease (I-SceI), which is found by chance only once in 7×1010 bp of genomic sequences, and can thus form a near bioorthogonal pair with I-SceI for DNAzyme activation with minimal effect on living cells. Once I-SceI is expressed inside cells, it cleaves at the recognition site, allowing the DNAzyme to adopt its active conformation. The activated DNAzyme sensor is then able to specifically catalyze cleavage of a substrate strand in the presence of Mg2+ to release the fluorophore-labeled DNA fragment and produce a fluorescent turn-on signal for Mg2+ . Thus I-SceI bioorthogonally activates the 10-23 DNAzyme for imaging of Mg2+ in HeLa cells.
