The noncovalent interaction between various polymethine dyes (45 compounds in total) and a spike protein (S), one of the main structural component SARS-CoV-2 coronavirus, is studied silico (molecular docking) to develop effective probes detect virus. energies spatial configurations complexes dye molecules with S are found. We showed that cationic neutral squarylium do not form stable S. Some an...

Several methods (e.g., UV/H2O2 oxidation, adsorption, flocculation-precipitation) are normally employed to remove dye from water. A new technique based on liquid/liquid extraction using reverse micelles is proposed whereby recovery of solvent and reuse of dye is possible. Experiments were conducted by mixing a known quantity of dye in aqueous phase and solvent-containing surfactants in a simple...

Contrast in confocal microscopy of phase-separated monolayers at the air-water interface can be generated by the selective adsorption of water-soluble fluorescent dyes to disordered monolayer phases. Optical sectioning minimizes the fluorescence signal from the subphase, whereas convolution of the measured point spread function with a simple box model of the interface provides quantitative asse...

Na-bentonite was prepared and tested as an adsorbent for a dye (Reactive Blue2) removal from aqueous solution. The effect of various experimental parameters was investigated using a batch adsorption technique. In this manner, initial dye concentration, pH of the initial dye solution, temperature and time contact effects upon dye adsorption on Na–bentonite having a structural formula of (Si7.86 ...

In this paper, the adsorption of Congo red dye from an aqueous solution using chitosan-coated pumice (CCP) has been studied. The abundant natural Irind mine (Republic Armenia) was successfully activated by acid activation method and modified with chitosan. adsorbent applied as a low-cost, environmentally-friendly for removal solution. samples were characterized Fourier-transform infrared spectr...

Occlusion of copolymer particles within inorganic crystalline hosts not only provides a model for understanding the crystallisation process, but also may offer a direct route for the preparation of novel nanocomposite materials with emergent properties. In the present paper, a series of new well-defined anionic diblock copolymer nanoparticles are synthesised by polymerisation-induced self-assem...
