Abstract
Abnormal mitochondrial state has been implicated in the pathogenesis of various diseases including neurodegenerative disorders, myopathies, cardiovascular diseases, and cancers. Assessing mitochondrial functionality can be achieved by monitoring alterations in mitochondrial polarity and mitochondrial DNA (mtDNA) integrity, which serve as valuable biomarkers. Hydrogen sulfide (H2S), a gaseous signaling molecule, plays a regulatory role in mitochondrial respiratory chain activity, ATP synthesis, and calcium ion balance, thereby influencing cellular metabolism and signal transduction. Investigating the interplay between mitochondrial H2S, polarity, and mtDNA can enhance our understanding of the underlying regulatory mechanisms involved in H2S-mediated mitochondrial functions. To address this, we designed a mitochondria-targeted multichannel fluorescent probe, HNA, capable of cascaded detection of H2S and polarity, as well as parallel detection of mtDNA. The probe exhibited a significant turn-on response to H2S, emitting at approximately 604 nm, while the product HNAP demonstrated high sensitivity to polarity within the wavelength range of 526-591 nm. Additionally, the probe was able to bind to DNA, resulting in an enhanced long-wave emission at 668 nm. Facilitated by HNA, our study provides novel insights into the role of mitochondrial H2S in maintaining mitochondrial polarity and validates its protective effect on mtDNA through antioxidative mechanisms. Overall, this work proposes a potential therapeutic strategy for modulating the inflammatory process in mitochondrial-related diseases.

Abstract
Diagnosis of diabetic cataract (DC) in the early stage is of great significance for drug intervention and surgery circumvention for DC patients. However, the lack of reliable imaging tools greatly limits the diagnosis of early DC. In this context, a fluorescent probe BBPy for hypochlorous acid (HOCl) is presented based on the oxidation of phenothiazine. The probe displays apparent emission enhancement at 562 nm toward HOCl with high selectivity, superb sensitivity (detection limit: 12.6 nM), and rapid response (within seconds). Using the probe, the HOCl generation in diabetic human lens epithelial cells was monitored, as well as the HOCl down-regulation during antioxidant treatment. Therefore, it is proposed that HOCl can be a promising biomarker for DC and fluorescence imaging technique can be regarded as a candidate tool for DC diagnosis.

Abstract
Mitochondrial DNA (mtDNA) as a class of important genetic material is easily damaged, which can result in a series of metabolic diseases, hereditary disease, and so on. mtDNA is an ultrasensitive indicator for the health of living cells due to the extremely short physiological response time of mtDNA toward damage (ca. 5.0 min). Therefore, the development of specific ultrasensitive fluorescent probes that can in real-time monitor mtDNA in vivo are of great value. With this research, we developed a near-infrared twisted intramolecular charge transfer (TICT) fluorescent probe YON. YON is a thread-like molecule with an A-π-D-π-A structure, based on the dicyanoisophorone fluorophore. The molecular design of YON enabled the specific binding with dsDNA (binding constant (K) = 8.5 × 105 M-1) within 1.3 min. And the appropriate water-oil amphiphilicity makes YON significantly accumulate in the mitochondria, enabling the specific binding to mtDNA. The fluorescence intensity at 640 nm of YON enhanced linearly with increasing concentrations of mtDNA. Dicyanoisophorone as the strong electron-withdrawing group that was introduced into both ends of the molecule resulted in YON being a classic quadrupole, so it could ultrasensitively detect trace mtDNA. The minimum detection limit was 71 ng/mL. Moreover, the large Stokes shift (λex = 435 nm, λem = 640 nm) makes YON suitable for "interference-free" imaging of mtDNA. Therefore, YON was used to monitor trace changes of mtDNA in living cells; more importantly, it could be used to evaluate the health of cells by monitoring microchanges of mtDNA, enabling the ultrasensitive evaluation of apoptosis.

Abstract
Carbon dots with long-wavelength emission (orange to red), high quantum yield (QY) and good biocompatibility are of great significance for biomedical applications, but achieving this is still a highly challenging task. In this work, multifunctional carbon dots with 54.4% orange emission (O-CDs) were prepared through one-pot solvothermal treatment of nileblueasulphate and citric acid as precursor for label-free recognition of morin and endogenous/exogenous hypochlorite (ClO-) and bioimaging in cellular and zebrafish. Morin can quench the luminescence of O-CDs by static quenching (SQ). The linear range is 5-125 μM and LOD is 0.84 μM. ClO- reduce the photoluminescence intensity of O-CDs via SQ. The linear range is 2.5-90 μM and LOD was 0.46 μM. In addition, The obtained O-CDs have successfully realized the monitoring of morin and endogenous/ exogenous ClO- in living cells and zebrafish owing to its superior biocompatibility, exceptional photostability and lower toxicity. This work opens up a novel opportunity for the development of long-wavelength emission multifunctional nanomaterial with high quantum yield based on CDs for biosensing, biolabeling and biomedical optical imaging.

Abstract
Mitochondrial DNA (mtDNA) is the genetic information of mitochondrion, and its structure is circular double-stranded. Despite the diminutive size of the mitochondrial genome, mtDNA mutations are an important cause of mitochondrial diseases which are characterized by defects in oxidative phosphorylation (OXPHOS). Mitochondrial diseases are involved in multiple systems, particularly in the organs that are highly dependent on aerobic metabolism. The diagnosis of mitochondrial disease is more complicated since mtDNA mutations can cause various clinical symptoms. To realize more accurate diagnosis and treatment of mitochondrial diseases, the detection of mtDNA and the design of drugs acting on it are extremely important. Over the past few years, many probes and therapeutic drugs targeting mtDNA have been developed, making significant contributions to fundamental research including elucidation of the mechanisms of mitochondrial diseases at the genetic level. In this review, we summarize the structure, function, and detection approaches for mtDNA. The most current topics in this field, such as mechanistic exploration and treatment of mtDNA mutation-related disorders, are also reviewed. Specific attention is given to discussing the design and development of these probes and drugs for mtDNA. We hope that this review will provide readers with a comprehensive understanding of the importance of mtDNA, and promote the development of effective molecules for theragnosis of mtDNA mutation-related diseases.

Abstract
![]()
Alzheimer’s
disease (AD) is a neurodegenerative disease,
and β-amyloid (Aβ) is believed to be a causative factor
in AD pathology. The abnormal deposition of Aβ is believed to
be responsible for progression of AD. In order to facilitate the imaging
of Aβ in vivo, suitable probe molecules with
a near-infrared emission wavelength that can penetrate the blood–brain
barrier (BBB) were utilized. The commercial fluorescent probe thioflavin-T
(ThT) is used to image Aβ; however, because of its short emission
wavelength and poor BBB penetration, ThT can only be used in vitro. With this research, based on ThT, we design three
fluorescent probes (SZIs) having a longer emission wavelength in order
to image Aβ aggregates. SZIs with different numbers of double
bonds respond to Aβ aggregates. The SZIs have a structure similar
to ThT, and as such, the SZIs are also unable to penetrate the BBB.
To deal with the problem, we develop nanocomposites (MSN-Lf@SZIs)
to deliver SZIs into the brain of AD mouse and image Aβ successfully.
These new nanocomposites are able to deliver the dyes into the brain
and facilitate Aβ imaging in vivo.

Abstract
Hepatic ischemia-reperfusion (IR) injury is a severe pathophysiological event during liver surgery or transplantation and could lead to liver failure or even death. The energy supply of mitochondria plays an essential role in preventing IR injury. Mitochondrial DNA (mtDNA) is involved in maintaining the balance of energy by participating in an oxidative phosphorylation process. However, the exact relationship between IR and mtDNA remains unclear by reason of the lack of an accurate real-time analysis method. Herein, we fabricated a mitochondria-targeting fluorescent probe (mtDNA-BP) to explore mtDNA stability and supervise the changes in mtDNA in IR liver. By virtue of pyridinium electropositivity and suitable size, mtDNA-BP could accumulate in mitochondria and insert into the mtDNA groove, which made mtDNA-BP fluoresce strongly. This is attributed to the reduction of the intramolecular rotation energy loss that is restricted by DNA. By in situ fluorescence imaging, we observed in real time that mtDNA damage was aggravated by deteriorating IR injury, so the ROS-mtDNA-mediated IR damage signal pathway was speculated. Furthermore, on the basis of mtDNA-BP real-time response capability for mtDNA, we established a drug-screening method for inhibiting IR injury and found superior therapeutic performance of two potential drugs: pioglitazone and salidroside. This work contributes to our understanding of mtDNA-related disease and provides a new drug analysis method.
