Abstract
In this study, a quantitative analysis of nitrate in aqueous solution was performed through the combination of an oxazine170 perchlorate⁻ethyl cellulose (O17-EC) membrane with aluminum-containing compounds. Aluminum of Devarda's alloy (DA) or a clay hydrotalcite (HT) was employed for the reduction of nitrate to produce ammonia, and the produced ammonia was detected by the O17-EC membrane. The method of combining the O17-EC membrane with aluminum compounds has showed a broad detection range of nitrate. That is, the DA was combined with the O17-EC membrane and showed the linear nitrate detection ranges of 1⁻10 mM and 10⁻100 mM, while the O17-EC membrane immobilized with the clay HT showed a linear detection range of 0.1⁻1 mM nitrate. The visual color transition of the nitrate-sensing membranes at different nitrate concentrations was clearly observed under sunlight or irradiation of a light-emitting diode (LED) at an excitation wavelength of 470 nm (LED470).

Abstract
In this study, the oxazine 170 perchlorate (O17)-ethylcellulose (EC) membrane was successfully exploited for the fabrication of creatine- and creatinine-sensing membranes. The sensing membrane exhibited a double layer of O17-EC membrane and a layer of enzyme(s) entrapped in the EC and polyurethane hydrogel (PU) matrix. The sensing principle of the membranes was based on the hydrolytic catalysis of urea, creatine, and creatinine by the enzymes. The reaction end product, ammonia, reacted with O17-EC membrane, resulting in the change in fluorescence intensities at two emission wavelengths (λem = 565 and 625 nm). Data collected from the ratio of fluorescence intensities at λem = 565 and 625 nm were proportional to the concentrations of creatine or creatinine. Creatine- and creatinine-sensing membranes were very sensitive to creatine and creatinine at the concentration range of 0.1–1.0 mM, with a limit of detection (LOD) of 0.015 and 0.0325 mM, respectively. Furthermore, these sensing membranes showed good features in terms of response time, reversibility, and long-term stability. The interference study demonstrated that some components such as amino acids and salts had some negative effects on the analytical performance of the membranes. Thus, the simple and sensitive ratiometric fluorescent sensors provide a simple and comprehensive method for the determination of creatine and creatinine concentrations in urine.

Abstract
Although seminaphtorhodafluor (SNARF) dyes are already widely used to measure pH in cells and at biofilms, their synthesis has low yield and results in an unspecific position of a carboxy-group. The separation of 5'- and 6'-carboxy-SNARF reveals a pKa difference of 0.15, calling into question pH measurements with the (commercially available) mixture. Here we replace the bulky external dicarboxyphenyl ring with a propionate group and evaluate the spectral properties of the new derivative. Proceeding to the ethyl-iodoacetamide, covalent linkage to cysteine protein sites is achieved efficiently as shown with a cyanobacterial phytochrome, extending the scarce application of SNARF in bio-labelling in the current literature. Application in fluorescence lifetime imaging is demonstrated both with the lifetime-based and ratiometric-yield method.

Abstract
Ratiometric fluorescent sensors were constructed from RNA aptamers by generating modular ribonucleopeptide complexes. Fluorescent ribonucleopeptides containing fluorophore seminaphthorhodafluor tethered to their peptide subunit revealed a dual emission property, which permitted a ratiometric fluorescent measurement of a substrate-binding event. The strategy successfully afforded ratiometric fluorescent sensors for biologically active small ligands, tetracycline, dopamine and streptomycin.

Abstract
Biosensors allow the direct detection of molecular analytes, by associating a biological receptor with a transducer able to convert the analyte-receptor recognition event into a measurable signal. We review recent work aimed at developing synthetic fluorescent molecular sensors for a variety of analytes, based on peptidic receptors labeled with environmentally sensitive fluorophores. Fluorescent indicators based on synthetic peptides are highly interesting alternatives to protein-based sensors, since they can be synthesized chemically, are stable, and can be easily modified in a site-specific manner for fluorophore coupling and for immobilization on solid supports.

Abstract
Fluorescent biosensors to detect the bona fide events of biologically important molecules in living cells are increasingly demanded in the field of molecular cell biology. Recent advances in the development of fluorescent biosensors have made an outstanding contribution to elucidating not only the roles of individual biomolecules, but also the dynamic intracellular relationships between these molecules. However, rational design strategies of fluorescent biosensors are not as mature as they look. An insatiable request for the establishment of a more universal and versatile strategy continues to provide an attractive alternative, so-called modular strategy, which permits facile preparation of biosensors with tailored characteristics by a simple combination of a receptor and a signal transducer. This review describes an overview of the progress in design strategies of fluorescent biosensors, such as auto-fluorescent protein-based biosensors, protein-based biosensors covalently modified with synthetic fluorophores, and signaling aptamers, and highlights the insight into how a given receptor is converted to a fluorescent biosensor. Furthermore, we will demonstrate a significance of the modular strategy for the sensor design.

Abstract
The creation of novel bioanalytical tools for the detection and monitoring of a range of important target substances and biological events in vivo and in vitro is a great challenge in chemical biology and biotechnology. Protein-based fluorescent biosensors--integrated devices that convert a molecular-recognition event to a fluorescent signal--have recently emerged as a powerful tool. As the recognition units various proteins that can specifically recognize and bind a variety of molecules of biological significance with high affinity are employed. For the transducer, fluorescent proteins, such as green fluorescent protein (GFP) or synthetic fluorophores, are mostly adopted. Recent progress in protein engineering and organic synthesis allows us to manipulate proteins genetically and/or chemically, and a library of such protein scaffolds has been significantly expanded by genome projects. In this review, we briefly describe the recent progress of protein-based fluorescent biosensors on the basis of their platform and construction strategy, which are primarily divided into the genetically encoded fluorescent biosensors and chemically constructed biosensors.

Abstract
Semisynthetic fluorescent biosensors consisting of a protein framework and a synthetic fluorophore are powerful analytical tools for specific detection of biologically relevant molecules. We report herein a novel method that allows for the construction of turn-on fluorescent semisynthetic biosensors in a one-step manner. The strategy is based on the ligand-directed tosyl (LDT) chemistry, a new type of affinity-guided protein labeling scheme which can site-specifically introduce synthetic probes to the surface of proteins with concomitant release of the affinity ligands. Novel quenched ligand-directed tosylate (Q-LDT) reagents were designed by connecting an organic dye to a conjugate of a protein ligand and a fluorescence quencher through a tosyl linker. The Q-LDT-mediated labeling directly converts a natural protein to a fluorescently labeled protein that remains noncovalently complexed with the cleaved ligand-tethered quencher. The fluorescence of this labeled protein is initially quenched and only in the presence of specific analytes is the fluorescence enhanced (turned on) due to the expulsion of the ligand-quencher fragment. Using a single labeling step, this approach was successfully applied to carbonic anhydrase II (CAII) and a Src homology 2 (SH2) domain to generate turn-on fluorescent biosensors toward CAII inhibitors and phosphotyrosine peptides, respectively. Detailed investigations revealed that the obtained biosensors exhibit their natural ligand selectivity. The high target-specificity of the LDT chemistry also allowed us to prepare the SH2 domain-based biosensor not only in a purified form but also in a bacterial cell lysate. These results demonstrate the utility of the Q-LDT-based approach to expand the applications of semisynthetic biosensors.
