Abstract
Ferroptosis is a non-apoptotic form of cell death characterized by iron-dependent lipid peroxidation and glutathione (GSH) depletion. Despite recent advances, challenges remain in understanding the bidirectional interactions or interplay between organelles during ferroptosis. In this study, we aimed to understand the interplay between mitochondria (Mito) and lysosomes (Lyso) in cell homeostasis and ferroptosis. For this purpose, we designed a single fluorescent probe that marks GSH in Mito and hypochlorous acid (HOCl) in Lyso with two distinct emissions. Using this dual-targeted single fluorescent probe (9-morphorino pyronine), we detected Mito-Lyso interplay in ferroptosis. We disclosed differences in Mito-Lyso interplay depending on the induction of ferroptosis. Although erastin treatment decreased GSH, RSL3 triggered a HOCl burst, and FIN56- and FINO2-induced ferroptosis increased GSH and HOCl. Additionally, we showed that only extracellular vesicles generated during erastin-induced ferroptosis could spontaneously move and dock to neighboring cells, resulting in accelerated cell death.

Abstract
Aberrant autophagy of the endoplasmic reticulum (reticulophagy) is engaged in diverse pathological disorders. Herein, we reported sensitive imaging of reticulophagy with ER-Green-proRed, a diad combining a solvatochromic entity of trifluoromethylated naphthalimide for long-term ER tracking by green fluorescence and an entity of rhodamine-lactam fluorogenic to lysosomal acidity. Stringently accumulated in the ER to give green fluorescence, ER-Green-proRed exhibits robust red fluorescence upon codelivery with the ER subdomain into lysosomes. The relevance of turn-on red fluorescence to reticulophagy was validated by reticulophagy modulated by starvation, reticulophagic receptors, and autophagy inhibition. This imaging method was successfully employed to discern reticulophagy induced by various pharmacological agents. These results show the potential of ER-targeted pH probes, as exemplified by ER-Green-proRed, to image reticulophagy and to identify reticulophagy inducers.

Abstract
Macroautophagic/autophagic turnover of endoplasmic reticulum (reticulophagy) is critical for cell health. Herein we reported a sensitive fluorescence-on imaging of reticulophagy using a small molecule probe (ER-proRed) comprised of green-emissive fluorinated rhodol for ER targeting and nonfluorescent rhodamine-lactam prone to lysosome-triggered red fluorescence. Partitioned in ER to exhibit green fluorescence, ER-proRed gives intense red fluorescence upon co-delivery with ER into acidic lysosomes. Serving as the signal of reticulophagy, the turning on of red fluorescence enables discernment of reticulophagy induced by starvation, varied levels of reticulophagic receptors, and chemical agents such as etoposide and sodium butyrate. These results show ER probes optically activatable in lysosomes, such as ER-proRed, offer a sensitive and simplified tool for studying reticulophagy in biology and diseases.Abbreviations: Baf-A1, bafilomycin A1; CCCP, carbonyl cyanide m-chlorophenyl hydrazone; CQ, chloroquine diphosphate; ER, endoplasmic reticulum; FHR, fluorinated hydrophobic rhodol; GFP, green fluorescent protein; Reticulophagy, selective autophagy of ER; RFP, red fluorescent protein; ROX, X-rhodamine; UPR, unfolded protein response.

Abstract
The in-depth study of the interplay and cooperation between multiple organelles is an important biological task. Single fluorescent probes for separate visualization of multiple organelles is a desirable molecular tool, but the construction of such a probe is extremely difficult owing to the lack of valid strategies. In this work, utilizing the reversible cyclization reaction and intermolecular π stacking mechanism, a robust fluorescent probe is constructed to discriminatively illuminate lipid droplets (LDs), mitochondria, and lysosomes with blue, green, and red emission colors, respectively. Using the probe, the interplays and cooperation between LDs, mitochondria, and lysosomes are successfully studied, and the critical roles of lysosomes and LDs during mitochondrial fission are successfully revealed. Furthermore, this unique probe reveals the sequential damage of mitochondria and lysosomes during apoptosis through the successive fading of green and red emission. Thereby, the probe enables the discrimination of health state, early apoptosis, and late apoptosis of cells with three different sets of fluorescent signals. Overall, the robust probe is a desirable molecular tool to reveal the interactions between the three organelles, and investigate cell apoptosis and relative areas.

Abstract
Type I photodynamic therapy (PDT) with less oxygen consumption shows great potential to overcome the malignant hypoxia in solid tumors. Herein, a novel meso phosphate-substituted pyronin PY-P and its nanoparticles (PY-P NPs) were prepared as an efficient type I organic photosensitizer. The in vivo data prove that PY-P NPs have outstanding low dark toxicity but high photocytotoxicity under hypoxia (<1% O2).

Abstract
This review highlights the biological importance of mitochondrial energy metabolism and the applications of multiple optical/electrochemical approaches to determine energy metabolites. Mitochondria, the main sites of oxidative phosphorylation and adenosine triphosphate (ATP) biosynthesis, provide the majority of energy required by aerobic cells for maintaining their physiological activity. They also participate in cell growth, differentiation, information transmission, and apoptosis. Multiple mitochondrial diseases, caused by internal or external factors, including oxidative stress, intense fluctuations of the ionic concentration, abnormal oxidative phosphorylation, changes in electron transport chain complex enzymes and mutations in mitochondrial DNA, can occur during mitochondrial energy metabolism. Therefore, developing accurate, sensitive, and specific methods for the in vivo and in vitro detection of mitochondrial energy metabolites is of great importance. In this review, we summarise the mitochondrial structure, functions, and crucial energy metabolic signalling pathways. The mechanism and applications of different optical/electrochemical methods are thoroughly reviewed. Finally, future research directions and challenges are proposed.

Abstract
Dysfunctional organelles and defective turnover of organelles are engaged in multiple human diseases, but are elusive to image with conventional organelle probes. To overcome this, we developed intra-mitochondrial CLICK to assess mitophagy (IMCLAM), using a pair of conventional ΔΨm probes, where each probe alone fails to track dysfunctional mitochondria. The in situ formed optical triad is stably trapped in mitochondria without resorting to ΔΨm. Utilizing an acidity-responsive ΔΨm probe, IMCLAM enabled fluorescence-on detection of mitophagy by sensing pH acidification upon delivery of mitochondria into lysosomes. Moreover, we applied IMCLAM to assay mitophagy induced by pharmacological compounds in living cells and wild-type zebrafish embryos. Thus, IMCLAM offers a simplified tool to study mitochondria and mitophagy and provide a basis for screening mitophagy-inducing compounds. Abbreviations: CCCP, carbonyl cyanide m-chlorophenylhydrazone; IMCLAM, intra-mitochondrial CLICK to assess mitophagy; ROX, X-rhodamine; SPAAC, stain-promoted azide-alkyne Click Chemistry; TPP, triphenylphosphonium.

Abstract
Metabolic glycan labeling (MGL) has been employed for diverse purposes, such as cell surface glycan imaging and tumor surface engineering. We herein reported organelle-specific MGL (OMGL) for selective tagging of the inner limiting membrane of lysosomes over the cell surface. This is operated via acidity-promoted accumulation of optical probes in lysosomes and bioorthogonal ligation of the trapped probes with 9-azidosialic acid (AzSia) metabolically installed on lysosomal membrane proteins. Overcoming the limitation of classical organelle probes to dissipate from stressed organelles, OMGL enables optical tracking of pH-elevated lysosomes in exocytosis and membrane-permeabilized lysosomes in different cell death pathways. Thus, OMGL offers a new tool to study lysosome biology.

Abstract
Autophagy is an adaptive catabolic process functioning to promote cell survival in the event of inappropriate living conditions such as nutrient shortage and to cope with diverse cytotoxic insults. It is regarded as one of the key survival mechanisms of living organisms. Cells undergo autophagy to accomplish the lysosomal digestion of intracellular materials including damaged proteins, organelles, and foreign bodies, in a bulk, non-selective or a cargo-specific manner. Studies in the past decades have shed light on the association of autophagy pathways with various diseases and also highlighted the therapeutic value of autophagy modulation. Hence, it is crucial to develop effective approaches for monitoring intracellular autophagy dynamics, as a comprehensive account of methodology establishment is far from complete. In this review, we aim to provide an overview of the major current fluorescence-based techniques utilized for visualizing, sensing or measuring autophagic activities in cells or tissues, which are categorized firstly by targets detected and further by the types of fluorescence tools. We will mainly focus on the working mechanisms of these techniques, put emphasis on the insight into their roles in biomedical science and provide perspectives on the challenges and future opportunities in this field.

Abstract
Three aggregation-induced emission active fluorescent compounds, TPA-Pyr-Octane, TPA-Pyr-Br, and TPA-Pyr-Thiourea (TPA = triphenylamine pyridinium), are synthesized; their tiny differences in chemical structures result in a huge difference in cell-imaging applications. Especially, incorporating thiourea into fluorescent probes is found as a reliable strategy for mitochondrion-targeted imaging and superoxide anion tracking in living cells, which is possibly due to the presence of hydrogen bonding between thiourea and mitochondrion proteins. This finding is very useful for the design of biosensors and delivery carriers in disease treatment.

Abstract
Mitochondrial DNA (mtDNA) plays important roles in diverse physiological processes and myriad diseases. We herein report mtDNA imaging with a chameleon sensor containing a cationic rhodamine B (RB) entity for mitochondria targeting and a fluorogenic SYBR Green-I (SG) entity for DNA sensing. SG-RB selectively binds to mtDNA and gives green SG fluorescence in mitochondria of living cells but gives red RB fluorescence upon delivery of mitochondria into lysosomes in mitophagy. With the dual-color imaging, mtDNA aggregation and elevated mitophagy were identified in HeLa cells stressed with anticancer doxorubicin. These results suggest the utility of organelle-redirected DNA sensors for live cell imaging of mtDNA involved in myriad pathological disorders.

Abstract
Monitoring cell viability is a crucial task essential for the fundamental studies in apoptosis, necrosis, and drug discovery. Cell apoptosis and necrosis are significant to maintain the cell population, and their abnormality can lead to severe diseases including cancer. During cell death, significant changes occur in the intracellular contents and physical properties, such as decrease of esterase activity, depolarization of the mitochondrial membrane potential (ΔΨm), increase of caspase content, dissipation of membrane asymmetry, and loss of membrane integrity. To detect cell viability, the fluorescent probes have been developed by taking advantage of these biological parameters and using various fluorescence mechanisms. These fluorescent probes can serve as powerful tools to facilitate the research in biology and pathology. In this Account, the representative examples of the fluorescent probes for cell viability during the past decades have been summarized and classified into five types based on the biological changes. The basic principle, design strategy, fluorescence mechanisms, and molecular construction of these fluorescent probes have been discussed. Furthermore, the intrinsic characteristics and merits of these probes have been illustrated. Particularly, this Account describes our recent works for the design and synthesis of the fluorescent probes to detect cell viability in the dual-color and reversible modes. The dual-color and reversible fluorescent probes are highlighted owing to their unique benefits in accurate and dynamic detection of cell viability. In general, the dual-color fluorescent probes were constructed based on the loss of esterase activity during cell death. Excited-state intramolecular proton transfer (ESIPT) and intramolecular charge transfer (ICT) process were exploited for the probe design. The construction of such dual-color probes were realized by the acetate of the phenyl group on fluorophores. Esterases in healthy cells hydrolyze the acetate and bring a spectral shift to the probes. Moreover, reversible fluorescent probes for cell viability were designed based on the depolarization of ΔΨm, with relocalization properties dependent on ΔΨm. The probes target mitochondria in healthy cells with high ΔΨm, while they are relocalized into the nucleus in unhealthy cells with depolarized ΔΨm. As ΔΨm is reversibly changed according to the cell viability, these probes reversibly detect cell viability. The reversible and simultaneously dual-color fluorescent probes were developed based on the relocalization mode and aggregation-induced emission shift. The probes target mitochondria to form aggregates with deep-red emission, while they migrate into the nucleus to present in monomers with green fluorescence. In this manner, the probes enable dual-color and reversible detection of cell viability. Fluorescent probes for cell viability based on sensing the membrane integrity, caspase activity, and membrane symmetry are also presented. High-polarity and large-size fluorescent probes impermeable to the intact lipid bilayer selectively target apoptotic cells with a destructive plasma membrane. Fluorescent probes sensing caspases in a turn-on manner exclusively light up apoptotic cells with caspase expression. Membrane-impermeable probes with high affinity to phosphatidylserine (PS) specifically stain the plasma membrane of dead cells, since PS flip-flops to the outer leaflet of the membrane during cell death. In summary, this Account illustrates the basic principles, design strategies, characteristics, and advantages of the fluorescent probes for cell viability, and it highlights the dual-color and reversible probes, which can promote the development of fluorescent probes, apoptosis studies, drug discovery, and other relative areas.

Abstract
Mitophagy, as an evolutionarily conserved cellular process, plays a crucial role in preserving cellular metabolism and physiology. Various microenvironment alterations assigned to mitophagy including pH, polarity, and deregulated biomarkers are increasingly understood. However, mitophagy-specific viscosity dynamic in live cells remains a mystery and needs to be explored. Here, a water-soluble mitochondria-targetable molecular rotor, ethyl-4-[3,6-bis(1-methyl-4-vinylpyridium iodine)-9 H-carbazol-9-yl)] butanoate (BMVC), was exploited as a fluorescent viscosimeter for imaging viscosity variation during mitophagy. This probe contains two positively charged 1-methyl-4-vinylpyridium components as the rotors, whose rotation will be hindered with the increase of environmental viscosity, resulting in enhancement of fluorescence emission. The results demonstrated that this probe operates well in a mitochondrial microenvironment and displays an off-on fluorescence response to viscosity. By virtue of this probe, new discoveries such as the mitochondrial viscosity will increase during mitophagy are elaborated. The real-time visualization of the mitophagy process under nutrient starvation conditions was also proposed and actualized. We expect this probe would be a robust tool in the pathogenic mechanism research of mitochondrial diseases.

Abstract
Intracellular pH behaves as a vital parameter in the physiological and pathological processes. Novel small molecule probes for precise and dynamic monitoring of pH fluctuations in cellular physiological processes are still highly required. Herein, we present a hemicyanine-based probe (HcPH) detection of the pH changes during the intracellular process of mitochondria-associated autophagy. HcP-H exhibits highly reversible and ratiometric fluorescence detection of pH variation due to the deprotonation/protonation process, showing orange fluorescence (λem = 557 nm) in basic media (pH 8.0) and green fluorescence (λem = 530 nm) in acidic media (pH 6.2), respectively. Organelle localization experiment in HeLa cells demonstrates that this probe could selectively accumulate in mitochondria, showing almost overlap with that of Mito-Tracker Green FM. More importantly, Fluorescence imaging of HcP-H in HeLa cells subjected to the nutrient deprivation has demonstrated that this probe could monitor the intracellular pH changes in the mitochondria-associated process of mitophagy. It is clearly confirmed that HcP-H would serve as a promising fluorescent probe for tracing mitophagy in living cells.

Abstract
Ignored damage in adjacent normal tissue is fatal especially in some specific tumor therapy such as brain tumors, but it remains a great challenge to conquer due to random drug diffusion and tumor complexity. Herein, we show that hyperthermia in mitochondria, an interparticle plasmonic coupling effect activated nanoevent, selectively strikes tumor tissues without damaging adjacent normal tissues. Spherical gold nanoparticles with a mitochondria-targeting moiety, triphenyl phosphonium, preferentially accumulated inside tumor mitochondria and reached the threshold to activate interparticle plasmonic coupling effect among gold nanoparticles, realizing selective light-thermal conversion and mitochondrial dysfunction in tumor, whereas little hyperthermia and mitochondrial dysfunction were observed in adjacent normal tissues. In vivo study revealed that the temperature increment in tumor tissue with irradiation was nearly 4-fold that in adjacent normal tissue. This subcellular organelle-templated accumulation strategy provides a therapeutic model for highly selective tumor therapy with negligible local side effects.

Abstract
Exploring novel drug delivery systems with good stability and new structure to integrate pillararene and upconversion nanoparticles (UCNPs) into one system continues to be an important challenge. Herein, we report a novel preparation of a supramolecular upconversion nanosystem via the host-guest complexation based on carboxylate-based pillar[5]arene (WP5) and 15-carboxy-N,N,N-trialkylpentadecan-1-ammonium bromide (1)-functionalized UCNPs to produce WP5⊃1-UCNPs that can be loaded with the chemotherapeutic drug doxorubicin (DOX). Importantly, the WP5 on the surface of the drug-loaded nanosystem can be efficiently protonated under acidic conditions, resulting in the collapse of the nanosystem and drug release. Moreover, cellular uptake confirms that the nanosystem can enter human cervical cancer (HeLa) cells, resulting in drug accumulation in the cells. More importantly, cytotoxicity experiments demonstrated the excellent biocompatibility of WP5⊃1-UCNPs without loading DOX and that the nanosystem DOX-WP5⊃1-UCNPs exhibited an ability of killing HeLa cells effectively. We also investigated magnetic resonance imaging and upconversion luminescence imaging, which may be employed as visual imaging agents in cancer diagnosis and treatment. Thus, in the present work, we show a simple yet powerful strategy to combine UCNPs and pillar[5]arene to produce a unified nanosystem for dual-mode bioimaging-guided therapeutic applications.

Abstract
Organelles often feature parameters pertinent to functions and yet responsive to biochemical stress. The electropotential across the mitochondrial membrane (ΔΨm) is a crucial mediator of cell fates. Herein we report a bioorthogonal reaction enabled fluorescence-on probing of ΔΨm alterations featuring anionic fluorescein-triphenylphosphonium diad (F-TPP), which is released via intramitochondria Staudinger reaction triggered self-immolation of o-azidomethylbenzoylated F-TPP. Compared to classical cationic mitochondria-specific dyes, F-TPP is hydrophilic and negatively charged. Effectively discerning ΔΨm changes upon diverse stress inducers, the organelle-directed bioorthogonal imaging strategy offers unprecedented choices to probe mitochondrial biology with functional molecules that are otherwise inaccessible via physiological organelle-probe affinity.

Abstract
Two AIEgens are designed for tracking mitochondria and lysosomes with different emission colors using single wavelength excitation to visualize the mitophagy process.
Multiplexed cellular organelle imaging using single wavelength excitation is highly desirable for unravelling cellular functions but remains challenging. This requires the design of organelle specific fluorophores with distinct emission but similar absorption. Herein, we present two unique aggregation-induced emission (AIE) probes to track mitochondria and lysosomes simultaneously with emission colors that can be distinguished from that of the nucleus stain Hoechst 33342 upon single wavelength excitation. Compared to conventional organelle stains, the two AIE probes have larger Stokes shifts and higher photostability, which endow them with the capability to monitor bioprocesses, such as mitophagy with strong and sustained fluorescent signals. Moreover, both probes can also stain intracellular organelles in zebrafish larvae with good cell-penetrating capabilities, showing their great potential to monitor bioprocesses in vivo.

Abstract
The organelle-specific pH is crucial for cell homeostasis. Aberrant pH of lysosomes has been manifested in myriad diseases. To probe lysosome responses to cell stress, we herein report the detection of lysosomal pH changes with a dual colored probe (CM-ROX), featuring a coumarin domain with "always-on" blue fluorescence and a rhodamine-lactam domain activatable to lysosomal acidity to give red fluorescence. With sensitive ratiometric signals upon subtle pH changes, CM-ROX enables discernment of lysosomal pH changes in cells undergoing autophagy, cell death, and viral infection.
