Abstract
Hybrid small-molecule/protein fluorescent probes are powerful tools for visualizing protein localization and function in living cells. These hybrid probes are constructed by diverse site-specific chemical protein labeling approaches through chemical reactions to exogenous peptide/small protein tags, enzymatic post-translational modifications, bioorthogonal reactions for genetically incorporated unnatural amino acids, and ligand-directed chemical reactions. The hybrid small-molecule/protein fluorescent probes are employed for imaging protein trafficking, conformational changes, and bioanalytes surrounding proteins. In addition, fluorescent hybrid probes facilitate visualization of protein dynamics at the single-molecule level and the defined structure with super-resolution imaging. In this review, we discuss development and the bioimaging applications of fluorescent probes based on small-molecule/protein hybrids.

Abstract
Probe choice in single-molecule microscopy requires deeper evaluations than those adopted for less sensitive fluorescence microscopy studies. Indeed, fluorophore characteristics can alter or hide subtle phenomena observable at the single-molecule level, wasting the potential of the sophisticated instrumentation and algorithms developed for advanced single-molecule applications. There are different reasons for this, linked, e.g., to fluorophore aspecific interactions, brightness, photostability, blinking, and emission and excitation spectra. In particular, these spectra and the excitation source are interdependent, and the latter affects the autofluorescence of sample substrate, medium, and/or biological specimen. Here, we review these and other critical points for fluorophore selection in single-molecule microscopy. We also describe the possible kinds of fluorophores and the microscopy techniques based on single-molecule fluorescence. We explain the importance and impact of the various issues in fluorophore choice, and discuss how this can become more effective and decisive for increasingly demanding experiments in single- and multiple-color applications.

Abstract
Human serum albumin (HSA) can bind with numerous drugs, leading to a significant influence on drug pharmacokinetics as well as undesirable drug-drug interactions due to competitive binding. Probing the HSA drug binding site thus offers great opportunities to reveal drug-HSA binding profiles. In the present study, a fluorescent probe (E)-4-(2-(5-(4-(diphenylamino)phenyl)thiophen-2-yl)vinyl)-1-propylpyridin-1-ium (TTPy) has been prepared, which exhibits enhancement of deep-red to near-infrared (NIR) fluorescence upon HSA binding. The competitive binding assay indicated that TTPy can target the HSA binding site of fenamates, a group of non-steroidal anti-inflammatory drugs (NSAIDs), with moderate binding affinity (1.95 × 106 M-1 at 303 K). More interestingly, TTPy enables fluorescent labeling of HSA upon visible light irradiation. This study provides promising ways for HSA drug binding site identification and photochemical protein labeling.

Abstract
Long-wavelength fluorescent proteins (LWFPs) and LWFP-based sensors are indispensable tools for bioimaging and biosensing applications. However, it remains challenging to develop LWFPs with outstanding brightness and/or sensitivities, largely due to the lack of simple and effective molecular design strategies. Herein, we rationalized the molecular origins of a multi-donor strategy that affords significant bathochromic shifts and large Stokes shifts with minimal structural changes in the resulting protein fluorophores. We analyzed three key factors that affect the spectral properties of these fluorophores, including the (1) substituent position, (2) electron-donating strength, and (3) number of electron-donating groups. We further demonstrated that this simple design strategy is generalizable to various fluorophore families. We expect that this work can provide rational guidelines for developing fluorescent proteins (and small-molecule fluorophores) with long emission wavelengths and large Stokes shifts.

Abstract
A FRET-based fluorescence turn-on probe is designed, which employs a sydnonimine as the linker to match specific fluorophore and quencher pairs and releases the fluorescence after the "click-and-release" reaction. Furthermore, we realized selective fluorescence labeling by exploiting the mutual orthogonality between sydnonimine-DIBAC and tetrazine-1,3-Cp cycloaddition pairs.

Abstract
The unique role of the zinc (II) cation prompted us to cut a cross-section of the large and complex topic of the stimuli-responsive coordination polymers (CPs). Due to its flexible coordination environment and geometries, easiness of coordination-decoordination equilibria, "optically innocent" ability to "clip" the ligands in emissive architectures, non-toxicity and sustainability, the zinc (II) cation is a good candidate for building supramolecular smart tools. The review summarizes the recent achievements of zinc-based CPs as stimuli-responsive materials able to provide a chromic response. An overview of the past five years has been organised, encompassing 1, 2 and 3D responsive zinc-based CPs; specifically zinc-based metallorganic frameworks and zinc-based nanosized polymeric probes. The most relevant examples were collected following a consequential and progressive approach, referring to the structure-responsiveness relationship, the sensing mechanisms, the analytes and/or parameters detected. Finally, applications of highly bioengineered Zn-CPs for advanced imaging technique have been discussed.

Abstract
Self-labelling protein tags with fluorogenic probes serve as great fluorescence imaging tools to understand key questions of protein dynamics and functions in living cells. In the present study, we report a SNAP-tag fluorogenic probe 4c mimicking the chromophore of the red fluorescent protein Kaede. The molecular rotor properties of 4c were utilized as a fluorogenic probe for SNAP-tag, such that conjugation with SNAPf protein leads to inhibition of twisted intramolecular charge transfer, triggering fluorogenecity. Upon conjugation with SNAPf, 4c exhibited approximately a 90-fold enhancement in fluorescence intensity with fast labelling kinetics (k2 = 15 000 M-1 s-1). Biochemical and spectroscopic studies confirmed that fluorescence requires formation of folded SNAPf·4c covalent conjugate between Cys 145 and 4c. Confocal microscopy and flow cytometry showed that 4c is capable of detecting SNAPf proteins or SNAPf fused with a protein of interest in living cells. This work provides a framework to develop the large family of FP chromophores into fluorogenic probes for self-labelling protein tags.

Abstract
Fluorescence imaging is a powerful technique for the real-time noninvasive monitoring of protein dynamics. Recently, fluorogen activating proteins (FAPs)/fluorogen probes for protein imaging were developed. Unlike the traditional fluorescent proteins (FPs), FAPs do not fluoresce unless bound to their specific small-molecule fluorogens. When using FAPs/fluorogen probes, a washing step is not required for the removal of free probes from the cells, thus allowing rapid and specific detection of proteins in living cells with high signal-to-noise ratio. Furthermore, with different fluorogens, living cell multi-color proteins labeling system was developed. In this review, we describe about the discovery of FAPs, the design strategy of FAP fluorogens, the application of the FAP technology and the advances of FAP technology in protein labeling systems.

Abstract
A 1,8-naphthalimide-derived fluorogenic probe was reported to label SNAP-tag fusion proteins in living cells. The probe can rapidly label a SNAP-tag and exhibit a fluorescence increase of 36-fold due to the additive effects of environment sensitivity of fluorophores and inhibition of photo-induced electron transfer from O6-benzylguanine to the fluorophore. The labeling of intracellular proteins has been successfully achieved without a wash-out procedure.
