Second harmonic generation (SHG) was used to study both the adsorption of malachite green (MG), a positively charged organic dye, onto liposomes of different lipid compositions, and the transport kinetics of MG across the liposome bilayer in real time. We found that the dye adsorption increased linearly with the fraction of negatively charged lipids in the bilayer. Similarly, the transport rate...

A facile method of solution combustion was used to synthesize a new solid solution Bi(2)Ce(2)O(7). The structure was determined from powder X-ray diffraction (PXRD) and found to crystallize in the space group Fm3m with cell parameter a = 5.46936(9) Å. The particle sizes varied from 5 to 6 nm. The degradation of cationic dye malachite green (MG) was investigated under solar radiation as the band...

The organic dyes directly pollute the soil, water, plants and all living systems in the environment. In the present investigation, adsorption of brilliant green dye on silica from aqueous solution was studied. The dye adsorption mechanism was studied on the basic surface of silica. The adsorption parameters were optimized to maximum adsorption. The adsorption mechanism of brilliant green on sil...

A molecule or a molecular system always consists of excited states of different spin multiplicities. With conventional optical excitations, only the (bright) states with the same spin multiplicity of the ground state could be directly reached. How to reveal the dynamics of excited (dark) states remains the grand challenge in the topical fields of photochemistry, photophysics, and photobiology. ...

In this work, two low-cost wastes, bivalve shell (BS) and Zea mays L. husk leaf (ZHL), were investigated to adsorb malachite green (MG) from aqueous solutions. The ZHL was treated with calcined BS to give the BS-ZHL, and its ability to adsorb MG was compared with untreated ZHL, calcined BS and Ca(OH)(2)-treated ZHL under several different conditions: pH (2-8), adsorbent dosage (0.25-2.5 g L(-1)...

RNAs mediate many different processes that are central to cellular function. The ability to quantify or image RNAs in live cells is very useful in elucidating such functions of RNA. RNA aptamer-fluorogen systems have been increasingly used in labeling RNAs in live cells. Here, we use the malachite green aptamer (MGA), an RNA aptamer that can specifically bind to malachite green (MG) dye and ind...

Resistant strains of Aspergillus nidulans were obtained by one-step selection on high concentrations of various inhibitors; each strain was mutant in a different gene conferring resistance to actidione (Act), p-fluorophenylalanine (p f ) , teoquil ( te) , iodoacetate (Iod) or malachite green (mg). Some mutant alleles have been firmly, others tentatively, located. For comparative purposes attemp...

Malachite green (MG), N-methylated diaminotriphenylmethane, is one of the most common dyes in textile industry and has also been used as an effective antifungal agent. However, due to its negative impact on the environment and carcinogenic effects to mammalian cells, there is a significant interest in developing microbial agents to degrade this type of recalcitrant molecules. Here, an Exiguobac...

in this research psedomonas fluorescens as a probiotic, sodium chloride, plant extract (terminalia catappa), malachite green and formalin as antifungal agents were used daily for 19 days on rainbow trout fertilized eggs in order to compare their survival with untreated fertilized eggs in control group. results showed that the percent of live eggs (eyed) after 19 days treatment with p. fluoresce...
