Abstract
Luminescence imaging is a powerful and versatile technique for investigating cell physiology and pathology in living systems, making significant contributions to life science research and clinical diagnosis. In recent years, luminescent transition metal complexes have gained significant attention for diagnostic and therapeutic applications due to their unique photophysical and photochemical properties. In this Review, we provide a comprehensive overview of the recent development of luminescent transition metal complexes for bioimaging and biosensing applications, with a focus on transition metal centers with a d6, d8, and d10 electronic configuration. We elucidate the structure-property relationships of luminescent transition metal complexes, exploring how their structural characteristics can be manipulated to control their biological behavior such as cellular uptake, localization, biocompatibility, pharmacokinetics, and biodistribution. Furthermore, we introduce the various design strategies that leverage the interesting photophysical properties of luminescent transition metal complexes for a wide variety of biological applications, including autofluorescence-free imaging, multimodal imaging, organelle imaging, biological sensing, microenvironment monitoring, bioorthogonal labeling, bacterial imaging, and cell viability assessment. Finally, we provide insights into the challenges and perspectives of luminescent transition metal complexes for bioimaging and biosensing applications, as well as their use in disease diagnosis and treatment evaluation.

Abstract
During the past decade, there was a fast development of cell-based biomimetic systems, which are commonly derived from cell membranes, cell vesicles, or living cells. Such systems have unique and inherent bioinspired features originating from their parent biological systems. In particular, they are capable of (i) prolonging blood circulation time, (ii) avoiding immune response, (iii) targeting desired sites, (iv) providing antigens in cancer immunotherapy, and (v) loading and delivering therapeutic or imaging agents. Thus, these biomimetic systems are promising as prevention, detection, diagnosis, and therapeutic modalities. Though promising, these cell-based biomimetic systems are still far from wide application. One of the important reasons is the inevitable difficulty in their further efficient and precise functionalization. Bioorthogonal chemistry results in fast, specific, and high-yielding ligation under mild biological conditions without interactions with surrounding biomolecules or disturbance of the whole biosystem. Moreover, bioorthogonal chemical groups can be introduced into cells, especially into cell membranes, through cellular biosynthesis and metabolic incorporation. Hence, a specific and reliable approach for cell membrane functionalization based on bioorthogonal chemistry has been opportunely put forward and rapidly developed. In this Account, we summarize our recent research on the development of biomimetic systems by integrating bioorthogonal chemistry with biomimetic approaches. First, an exogenously supplied unnatural biosynthetic precursor (e.g., an amino acid or lipid) bearing a bioorthogonal group (e.g., azide or tetrazine) is fed to living cells and metabolically incorporated into targeted biomolecules via cellular biosynthesis regardless of the cell phenotype. After that, different functional molecules can be anchored to the cell membranes through bioorthogonal chemical reactions by using previously inserted "artificial chemical groups". Therefore, this safe, direct, and long-term engineering strategy endows the natural cell-based biomimetic systems with additional chemical or biological performances such as labeling, targeting, imaging, and therapeutic capabilities, providing a powerful tool for the construction of biomimetic systems. Interestingly, we have successfully fabricated various biomimetic systems and applied them in (1) living virus labeling, (2) targeting delivery and enrichment of drugs/imaging agents, and (3) disease theranostics. This Account may contribute to the further development of biomimetic systems and facilitate their biological and biomedical applications in the future. With this Account we also hope to attract more cooperative interests from different fields such as chemistry, materials science, biology, pharmacy, and medicine in promoting lab-to-clinic translation of cell-based biomimetic systems combined with these two cutting-edge techniques.

Abstract
![]()
Uncovering
the mechanisms of virus infection and assembly is crucial
for preventing the spread of viruses and treating viral disease. The
technique of single-virus tracking (SVT), also known as single-virus
tracing, allows one to follow individual viruses at different parts
of their life cycle and thereby provides dynamic insights into fundamental
processes of viruses occurring in live cells. SVT is typically based
on fluorescence imaging and reveals insights into previously unreported
infection mechanisms. In this review article, we provide the readers
a broad overview of the SVT technique. We first summarize recent advances
in SVT, from the choice of fluorescent labels and labeling strategies
to imaging implementation and analytical methodologies. We then describe
representative applications in detail to elucidate how SVT serves
as a valuable tool in virological research. Finally, we present our
perspectives regarding the future possibilities and challenges of
SVT.

Abstract
Oncolytic virotherapy is one of promising tumor therapy modalities. However, its therapeutic efficacy is still limited due to the immunogenicity and poor tumor-targeting capability. In this report, an engineered oncolytic vaccinia virus (OVV) was constructed by site-specifically introducing azide groups to the envelope of OVV during the in situ assembling process of virions. Subsequently, dibenzocyclooctynes (DBCO) derivate T7 peptide and DBCO derivate self-peptide were simultaneously conjugated to the azide-modified OVV (azide-OVV) via copper-free click chemistry. The infectivity of peptide-conjugated virus was well kept. Meanwhile, both of the targeting capacity to transferrin receptor (TfR)-overexpressed tumor cells and the in vivo blood circulation time increased. Therefore, the growth of TfR-positive tumor could be significantly inhibited after intravenously injecting the engineered OVV, while no noticeable side effects. This construction strategy can be popularized to other enveloped oncolytic virus (OV), thus a universal engineering platform can be provided for OV cancer therapy. Graphical Abstract An engineered oncolytic vaccinia virus (OVV) was constructed by bioconjugating DBCO derivate T7 peptide and DBCO derivate self-peptide with azide-modified OVV via copper-free click chemistry. As a result, the tumor inhibit effect was significantly enhanced attributed to the prolonged in vivo circulation time and improved targeting recognition capability.

Abstract
Entry is the first and critical step of viral infection, while the entry mechanisms of many viruses are still unclear due to the lack of efficient technology. In this report, by taking advantage of the single-virion fluorescence tracking technique and simultaneous dual-labeling methods for viruses we developed, the entry pathway of vaccinia virus from tiantan strain (VACV-TT) was studied in real-time. By combining with the technologies of virology and cell biology, we found that VACV-TT moved toward the Vero cell body along the filopodia induced by the virions interaction, and then, they were internalized through macropinocytosis, which was an actin-, ATP-dependent but clathrin-, caveolin-independent endocytosis. These results are of significant importance for VACV-TT-based vaccine vectors and oncolytic virus study.

Abstract
Quantum dots (QDs) have become one of the most promising luminescent materials for tracking viral infection in living cells. However, several issues regarding how QDs interact with the virus remain unresolved. Herein, the effects of Glutathione (GSH) capped CdTe QDs on virus were investigated by using pseudorabies virus (PRV) as a model. One-step growth curve and fluorescence colocalization analyses indicate that CdTe QDs inhibit PRV multiplication in the early stage of virus replication cycle by suppressing the invasion, but have no significant effect on the PRV penetration. Fluorescence spectrum analysis indicates that the size of QDs is reduced gradually after the addition of PRV within 30 min. Release of Cd2+ was detected during the interaction of QDs and PRV, resulting in a decreased number of viruses which can infect cells. Further Raman spectra and Circular Dichroism (CD) spectroscopy analyses reveal that the structure of viral surface proteins is altered by CdTe QDs adsorbed on the virus surface, leading to the inhibition of virus replication. This study facilitates an in-depth understanding of the pathogenic mechanism of viruses and provides a basis for QDs-labeled virus research.

Abstract
We have developed a new dual-color fluorescent biosensor for protein detection based on terminal protection of small-molecule-linked DNA and the enzymolysis of exonuclease III (Exo III). The determination of streptavidin (SA) was realized via fluorescence signals of the green color from quantum dots (QDs) and the red from [Ru(phen)2(dppx)](2+). In the absence of SA, biotin-DNA was degradated by the Exo III, thus making the [Ru(phen)2(dppx)](2+) employed as a fluorescence quencher to the QDs. With the addition of SA, dual-color response appeared because of the specific binding between SA and biotin so that the biotin-dsDNA was protected and combined with [Ru(phen)2(dppx)](2+), leading to the QDs recovery and the generating of [Ru(phen)2(dppx)](2+) fluorescence. This sensor exhibited high sensitivity with a low detection limit (2.11ng/mL) and firstly introduced dual-color QDs-ruthenium complex dyads to protein assay.

Abstract
An alternative method for labeling fully replicative enveloped viruses was developed, in which both the biosynthesis and metabolic incorporation of phospholipids in host cells were simultaneously utilized to introduce an azide group to the envelope of the vaccinia virus by taking advantage of the host-derived lipid membrane formation mechanism. Such an azide group could be subsequently used to fluorescently label the envelope of the virus via a bioorthogonal reaction. Furthermore, simultaneous dual-labeling of the virus through the virus replication was realized skillfully by coupling this envelope labeling strategy with "replication-intercalation labeling" of viral nucleic acid. For the first time, it is by natural propagation of the virus in its host cells in the presence of fluorophores that simultaneous dual-labeling of living viruses can be mildly realized with high efficiency in facile and mild conditions.

Abstract
Real-time tracking of the dynamic process of virus invasion is crucial to understanding the infection mechanism. For successful tracking, efficient labeling methods are indispensable. In this paper, we report a mild and reliable method for labeling viruses, especially with regard to easily disabled enveloped viruses. The copper-free click chemistry has been used to label enveloped viruses with quantum dots (QDs) by linking virions modified with azide to the QDs derived with dibenzocyclooctynes (DBCO). Both vaccinia virus (VACV) and avian influenza A virus (H9N2) can be specifically and rapidly labeled under mild conditions, with a labeling efficiency of more than 80%. The labeled virions were of intact infectivity, and their fluorescence was strong enough to realize single-virion tracking. Compared to previously reported methods, our method is less destructive, reliable, and universal, without specific requirements for the type and structure of viruses to be labeled, which has laid the foundation for long-term dynamic visualization of virus infection process.
