Carcinoma cell mitochondria preferentially accumulate and retain certain cationic dyes to a much greater extent than most normal cells. Thus, they can potentially serve as targets for highly selective photochemotherapy. We evaluated 10 rhodamine and cyanine dyes as carcinoma-specific mitochondrial photosensitizers in vitro. The most effective, N,N'-bis(2-ethyl-1,3-dioxolane)kryptocyanine (EDKC)...

Dye removal from industrial wastewater is an important environmental concern. So far, various physical and chemical treatment methods have been reviewed for the removal of dyes such as biological degradation, ion exchange, chemical precipitation, reverse osmosis, coagulation, flocculation, etc. However, these treatment processes have their limitations such as high cost, generation of toxic slud...

Magnetic NiFe2O4 nanoparticle (NFNPs) were synthesized by the microwave-assisted method using Tamarindus indica seeds as a green reducing agent’ for better readability. The identification of NFNPs was carried out X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) with energy dispersive analysis (EDX), transmission microscopy (TEM),...

We report a novel hybrid material Na2Mo4O13/α-MoO3 as highly efficient catalytic wet air oxidation (CWAO) catalyst, which showed the highest ever activity at room temperature and atmosphere pressure for the degradation of cationic red GTL. SEM and TEM analyses indicated that this hybrid catalyst has bamboo-shaped nanofiber morphology. In view of practical applications, the influence of some key...

Chemical properties of cationic biosorbents, the orange peel and the lemon peel, have been studied. ATR and Raman spectra indicated that the functional groups in the peels structure responsible for dye sorption are carboxyl groups (COOH and COOM, M=Na,K,Ca,Mg) and hydroxyl groups (OH). Increasing the mass of the peels in water suspensions a decrease in dissociation of both, the –COOH and –COOM ...

Peanut hull, an agricultural waste, proved to act as an efficient adsorbent for five anionic and cationic dyes. The process was found to be a pH dependent, suggesting the adsorption is controlled by interaction between the charged dye molecule and the surface charge on the adsorbent. The effect of variable parameters (contact time, pH, mass of adsorbent, dye concentration, agitation and activat...

spirometry has been used as a common diagnostic test in asthma. most of the patients with a mild asthma have a fev1 within normal range. hence, other diagnostic methods are usually used. the aim of this study was to evaluate whether eosinophil cationic protein (ecp) could be an accurate diagnostic marker of mild asthma. in this study diagnosis of asthma was made according to internationally acc...

this study examined the adsorption behavior of two cationic dyes used in textile industries (cibasic red 46 and ci basic blue 3) on tunisian clay used in pottery. the ability of pottery clay to remove thebasic dyes from aqueous solution was compared to that of the commercial powdered activated carbon (pac)and raw clay. physicochemical characteristics of these adsorbents were performed by boehm ...

The development of new strategies and photocatalytic materials for practical environmental solutions remains a great challenge, particularly due to the large energy demands associated with various remediation processes. In this paper, we report the fabrication of self-assembled ordered mesoporous TiO2 with highly crystalline anatase structures as well as high surface area, and characterize thei...

Solid waste (SW) from a biodiesel plant has been successfully used for the removal of the hazardous cationic water soluble dye methylene blue (MB) from an aqueous phase. Batch adsorption studies were carried out by monitoring the pH, amount of adsorbent, initial dye concentration and contact time. Attempts have also been made to monitor the adsorption process through Langmuir, Freundlich, Temki...
