Background: Fluorescence-based sensing is considered highly sensitive and fluorescent probes with improved properties are always preferred. Fluorescent carbon dots (CDs) are newly emerging quasi-spherical nanoparticles of less than 10 nm in size and belong to the carbon nanomaterial’s family. CDs have great potential as fluorescent probes and currently are under open discussion by the researchers due to their striking p Read More

Background: Chemosensor compounds are useful for sensitive, selective detection of cations and anions with fluorophore groups in an attempt to develop sufficient selectivity of the sensors. Although familiar fluorescent sensors utilize inter-molecular interactions with the cations and anions, an extraordinary endeavor was executed in the preparation of fluorescent-based sensor compounds. 4,4-difluoro-4- bora-3a,4a-diaza-s-ind Read More

Background: The optical properties of nanomaterials have evolved enormously with the introduction of nanotechnology. The property of materials to absorb and/or emit specific wavelength has turned them into one of the most favourite candidates to be effectively utilized in different sensing applications e.g, organic light emission diodes (OLEDs) sensors, gas sensors, biosensors, and fluorescent sensors. These materials have Read More

Background: The selection of capping agent depends on the method of synthesis, nature of nanoparticles (NPs), and type of the compounds to be analyzed. Therefore, different types of capping agents such as surfactants, drugs, amino acids, fatty acids, and polymers are used to increase stability of NPs, avoid aggregation, keep NPs away from one another, thereby achieving desired morphology as well as the size of NPs. I Read More

Aim: Selective and sensitive visual detection of Cu2+in aqueous solution at PPB level using an easily synthesized compound. Background: The search for a chemosensor that can detect Cu2+ is very long owing to the fact that an optimum level of Cu2+ is required for human health and the recommended amount of Cu2+ in drinking water is set to be 1-2 mgL-1. Thus, it is very important to detect Cu2+ even at a very low co Read More

Background: The traditional methods for the detection and quantification of Cu2+ and Fe3+ heavy metal ions are usually troublesome in terms of high-cost, non-portable, time-consuming, specialized personnel and complicated tools, so their applications in practical analyses is limited. Therefore, the development of cheap, fast and simple-use techniques/instruments with high sensitivity/selectivity for the detection of he Read More

Background: Derivatization of analytes is a quite convenient practice from an analytical perspective. Its vast prevalence is accounted by the availability of distinct reagents, primarily pragmatic for obtaining desired modifications in an analyte structure. Another reason for its handiness is typically to overcome limitations such as lack of sensitive methodology or instrumentation. The past decades have witnessed various ne Read More

Background: Glucosinolates (GLS) are important secondary metabolites in Cruciferae vegetables and herbs. Currently, the assays of total GLS determination are cumbersome (requiring acidic or enzymatic hydrolysis and addition of staining reagents), time-consuming, and indirect. High concentrations of inorganic salts are inevitably incorporated into the GLS products during separation. There is a need for a quantitative Read More
