We have developed an effective approach to stretching DNA molecules with the flow of fluid generated by spin coating. Well-stretched A DNA molecules were observed using atomic force microscopy. Substrate properties sensitively affected the stretching behavior of DNA. Our experimental findings revealed that a mica surface treated with crystal violet, a cationic dye molecule, is suitable to the s...

Several techniques have been used to quantify the cytotoxicity produced by Mycobacterium tuberculosis bacilli on cell monolayers; however, they are semi-quantitative or time consuming. Herein, a method based on crystal violet (CV) uptake by THP-1 cell monolayers is described. This colorimetric method quantifies the cytotoxic effect as a function of the number of remaining cells after the infect...

STATEMENT OF THE PROBLEM Oral candidiasis is the most common opportunistic infection affecting the human oral cavity. Photodynamic therapy, as one of its proposed treatment modalities, needs a distinct dye for achieving the best effect. PURPOSE The purpose of this study was to evaluate photosensitization effects of four distinct dyes on standard suspension of Candida albicans (C. albicans) an...

The economic viability of adsorbing crystal violet (CV) using pepper seed spent (PSS) as a biosorbent in an aqueous solution has been studied. A parametrical investigation was conducted considering parameters like initial concentration dye, time contact, pH value, and temperature variation. analysis experimental data obtained carried out by evaluating with the isotherms Freundlich, Sips, Tempki...

In the present study, silica aerogel- egg shell was synthesized for dye removal of colored wastewater. The nano composite structure was characterized by Fourier transform infrared spectra FTIR and scanning electron microscope SEM.The ability of nano composite absorption was assessed for removal basic violet 16BV16 dye from aqueous solutions and was compared with two other adsorbents such as egg...

Natural materials are widely used in the field of environmental remediation and appreciated for their surface physical chemical properties. Clay constitutes a typical example. In this work, we report evaluation sorbent photocatalytic potentials local clay two irrigated rice waters degradation crystal violet. The structural, textural compositional properties were investigated by Fourier Transfor...
