Abstract
Herein, we present a straightforward synthetic route for the design and synthesis of diverse heterobifunctional cyanine 5 dyes. We optimized the workup by harnessing the pH- and functional group-dependent solubility of the asymmetric cyanine 5 dyes. Therefore, purification through chromatography is deferred until the last synthesis step. Demonstrating successful large-scale synthesis, our modular approach prevents functional group degradation by introducing them in the last synthesis step. These modifiable heterobifunctional dyes offer significant utility in advancing biological studies.

Abstract
Fluorescence imaging is an invaluable tool to study biological processes and further progress depends on the development of advanced fluorogenic probes that reach intracellular targets and label them with high specificity. Excellent fluorogenic rhodamine dyes have been reported, but they often require long and low-yielding syntheses, and are spectrally limited to the visible range. Here we present a general strategy to transform polymethine compounds into fluorogenic dyes using an intramolecular ring-closure approach. We illustrate the generality of this method by creating both spontaneously blinking and no-wash, turn-on polymethine dyes with emissions across the visible and near-infrared spectrum. These probes are compatible with self-labelling proteins and small-molecule targeting ligands, and can be combined with rhodamine-based dyes for multicolour and fluorescence lifetime multiplexing imaging. This strategy provides access to bright, fluorogenic dyes that emit at wavelengths that are more red-shifted compared with those of existing rhodamine-based dyes.

Abstract
Multidrug-resistant bacteria pose a major threat to global health, even as newly introduced antibiotics continue to lose their therapeutic value. Against this background, deeper insights into bacterial interaction with antibiotic drugs are urgently required, whereas fluorescently labeled drug conjugates can serve as highly valuable tools. Herein, the preparation and biological evaluation of 13 new fluorescent antibiotic-Cy5 dye conjugates is described, in which the tuning of the polarity of the Cy5 dye proved to be a key element to achieve highly favorable properties for various fields of application.

Abstract
Fluorescence-based single-molecule techniques, mainly including fluorescence correlation spectroscopy (FCS) and single-molecule fluorescence resonance energy transfer (smFRET), are able to analyze the conformational dynamics and diversity of biological macromolecules. They have been applied to analysis of the dynamics of membrane proteins, such as membrane receptors and membrane transport proteins, due to their superior ability in resolving spatio-temporal heterogeneity and the demand of trace amounts of analytes. In this review, we first introduced the basic principle involved in FCS and smFRET. Then we summarized the labeling and immobilization strategies of membrane protein molecules, the confocal-based and TIRF-based instrumental configuration, and the data processing methods. The applications to membrane protein dynamics analysis are described in detail with the focus on how to select suitable fluorophores, labeling sites, experimental setup, and analysis methods. In the last part, the remaining challenges to be addressed and further development in this field are also briefly discussed.

Abstract
Multimodal imaging probes have attracted the interest of ongoing research, for example, for the surgical removal of tumors. Modular synthesis approaches allow the construction of hybrid probes consisting of a radiotracer, a fluorophore and a targeting unit. We present the synthesis of a new asymmetric bifunctional cyanine dye that can be used as a structural and functional linker for the construction of such hybrid probes. 68 Ga-DOTATATE, a well-characterized radiopeptide targeting the overexpressed somatostatin receptor subtype 2 (SSTR2) in neuroendocrine tumors, was labeled with our cyanine dye, thus providing additional information along with the data obtained from the radiotracer. We tested the SSTR2-targeting and imaging properties of the resulting probe 68 Ga-DOTA-ICC-TATE in vitro and in a tumor xenograft mouse model. Despite the close proximity between dye and pharmacophore, we observed a high binding affinity towards SSTR2 as well as elevated uptake in SSTR2-overexpressing tumors in the positron emission tomography (PET) scan and histological examination.

Abstract
Materials that have higher fluorescence emission in the solid state than molecules in solution have recently been paid more attention by the scientific community due to their potential applications in various fields. In this work, we newly synthesized benzoxazolyl-imidazole and benzothiazolyl-imidazole conjugates, which show aggregation-induced emission (AIE) features in their solid and aggregate states. It was found that oxygen and sulfur substitutions can dramatically influence the molecular structures and polarities of the dyes, leading to different degrees of the AIE phenomenon. The benzothiazolyl-imidazole molecule has lower polarity compared to that of benzoxazolyl-imidazole; therefore, the dye bearing a benzothiazolyl group shows higher emission intensity and dual emission in aqueous solution. Theoretical calculation results suggest that the benzothiazolyl-imidazole molecules might have electrostatic interactions between sulfur and nitrogen atoms, explaining the experimental observations of lower critical aggregation concentration and photophysical properties both in solution and in the solid state. The theoretical calculations agree with the experimental data, thus demonstrating a potent strategy to gain a deep understanding of the structure–property relationships to design solid-state fluorescent materials. The effect of heteroatoms on the structural and photophysical properties of donor-π-acceptor molecules, comprising imidazole and benzoxazolyl as well as imidazole and benzothiazolyl units, was investigated.![]()

Abstract
Here, we introduce isatoic anhydride as a sensitive and commodious fluorescent prelabel for detection of proteins in one-dimensional polyacrylamide gels. High reactivity of isatoic anhydride with nucleophiles in mild alkaline environments makes it an appropriate tag for labeling of biomolecules. In this study, we show that preelectrophoresis labeling of proteins with isatoic anhydride for few minutes at room temperature allows detection of 2-4 ng of standard proteins, BSA and lysozyme, per band. Proteins were successfully labeled in the presence of a wide range of common biological reagents and in crude cell extract. The labeled proteins have the same electrophoretic migration in comparison to unlabeled proteins; however the application of saturation labeling method results in slight band broadening. Compatibility of the method with downstream processes was assessed by tryptic digestion of labeled proteins and study of peptide mixture using gel electrophoresis which revealed partial digestion of labeled proteins due to lysine modification. The present procedure is sensitive, rapid, and inexpensive and is a promising alternative for current protein staining procedures, where downstream processes are not desired.

Abstract
Liver is responsible for the balance of blood glucose level. In this study, cholic acid and N-(2-hydroxy)-propyl-3-trimethylammonium chloride modified chitosan (HTCC-CA) was used as a liver-targeted vehicle for insulin delivery. A novel approach was developed to effectively load insulin by mixing insulin and HTCC-CA in 50% ethanol and water mixed solvent at pH 2 and then dialysis against pH 7.4 phosphate buffer subsequently against water. The insulin-loaded HTCC-CA nanoparticles have an average diameter of 86 nm and insulin loading efficiency of 98.7%. Due to random distribution of the hydrophobic cholic acid groups in HTCC-CA, some of the cholic acid groups located on the nanoparticle surface. Compared with free insulin, the nanoparticles increased in vitro cellular uptake of insulin to 466%, and the nanoparticles accumulated in liver for more time after subcutaneous injection into mice. The therapy for diabetic rats displayed that the nanoparticles increased the pharmacological bioavailability of insulin to 475% relative to free insulin, and the nanoparticles could maintain the hypoglycemic effect for more than 24 h. This study demonstrates that the nanoparticles with cholic acid groups on their surface possess liver-targeted property and biocompatible insulin-loaded HTCC-CA nanoparticles can effectively enhance the hypoglycemic effect of insulin.

Abstract
An aptamer-based competitive binding assay for one-step (i.e. no requirement of pre-treatment) quantitation of target molecules of interest has been developed. This method has been successfully employed for the fast and sensitive detection of the surface antigen of the hepatitis B virus (HBsAg). The key features of our method include its low intrinsic background noise, low costs, high resolution, and high sensitivity, enabling the detection of as low as 1.25 mIU mL(-1), approximately 40-fold better than that of the most widely used Abbott Architect assay for HBsAg detection, without the tedious extraction and/or washing procedures. Moreover, this assay has better recovery and accuracy than that of conventional competitive binding assay or others for HBsAg quantitation.

Abstract
A novel pH-sensitive near-IR (NIR) fluorescent dye was synthesised and utilised in the preparation of fluorescent polystyrene microspheres. Their photochemical properties, as well as the pH-dependent optical properties were investigated and showed high sensitivity to changes of pH in the range of 3.3–8.1. The fluorescence became stronger with the increase in pH. Importantly, the microspheres were able to work in aqueous media, which is highly valuable for use in biological applications.
