This paper presents the results of absorption spectra, fluorescence properties and the effect of solvents on UV-Vis spectra of dye quaternized 4-acetylamino-N-2-aminomethylpyridine-1,8-naphthalimide. The fluorescency of the dye was evaluated and its Stokes shift value was 6140 cm-1 in DMF. The solvatochromism behavior of the novel compound is investigated by studying its spectra in pure organic...

Carbon dots and their derivatives with fascinating photoluminescent properties have recently attracted tremendous scientific attention. This work describes the preparation of novel fluorescent bentonite clay (B), modified carbon dots...

Monomeric fluorescent proteins of different colors are widely used to study behavior and targeting of proteins in living cells. Fluorescent proteins that irreversibly change their spectral properties in response to light irradiation of a specific wavelength, or photoactivate, have become increasingly popular to image intracellular dynamics and superresolution protein localization. Until recentl...

Some new Schiff-base compounds based on pyrrole were synthesized by the reaction of 2-amino-1-methyl-4,5-diphenyl-1H-pyrrole-3-carbonitrile (1)with aromatic aldehydes (2a-2e) in ethanol/acetic acid at room temperature. The structures of the Schiff bases were characterized by full spectral data. The fluorescence emission intensity of the Schiff bases has bee...

olecular motions significantly influence the emissive behavior and properties of organic fluorescent molecules. However, achieving controllable emission remains a major challenge for fluorophores. In case aggregation-induced luminogens...

This short review is aimed at emphasizing the most prominent recent works devoted to fluorescence modulation of organic fluorescent or fluorogenic molecules by electrochemistry. still expanding research field not only addresses smart uses known design new ones, but also investigates development instrumentation providing time- and space-resolved information molecular level. Important considerati...

background and purpose: salmonella is a group of enterobacterias that cause infectious diseases in human and animals. typhoid, bacteremia, enterocolitis and salmonellosis which are caused by this bacterium are considered major health concerns in developing countries, such as iran. quick, accurate, reliable and early diagnosis is vital to prevent salmonella outbreak. materials and methods: there...

Fluorescent hydrogels have recently become one of the most prominent materials for smart confidential information protection. But it is still quite challenging to develop a 3D anticounterfeiting platform with on-demand decryption and transmission capacities, which are great importance achieve high-level data protection security. Herein, robust aggregation-induced emissive polymeric thermo-trigg...

By using a genetically modified thermostable protein (KTQ5C), we have synthesized protein-stabilized goldnanoclusters (AuNC@KTQ5C) with advantageous properties, such as heat stable fluorescent emission and resistant peroxidase-like activity.

This report describes the detailed procedures for Western blot analysis using fluorescent antibodies. After electrophoresis and subsequent electroblotting, the fluorescent-labeled antibodies were visible upon ultraviolet illumination of the polyvinylidene fluoride (PVDF) membranes and could then be photographed to give an accurate record of the blots. Fluorescent labeling allows for photographi...
