Photophysical deactivation behaviour of Rhodamine B using different graphite materials.

In the present work, an attempt has been made to elucidate the structural features of synthesized graphite materials, , expanded graphite (EG) and an expanded graphite/silver nanoparticles (EG/AgNPs) nanocomposite. In order to obtain knowledge about the functional groups present, the interlayer spacing between the carbon layers, topographical features, and the characterization of the materials were carried out using Fourier-transformer infrared spectroscopy, X-ray diffraction, Raman spectroscopy, field emission scanning electron microscopy-energy dispersive X-ray spectroscopy and atomic force microscope. Furthermore, the quenching efficiency of the synthesized graphite materials was also compared using Rhodamine B (Rhd B) as a fluorescent probe.

Exploring drying pattern of a sessile droplet of genomic DNA in the presence of hematite nanoparticles.

For the first time, drying pattern of a sessile droplet of genomic DNA, in the presence of hematite nanoparticles was sighted by polarizing optical microscopy (POM) in this research article. POM results indicated that only at an appreciably high concentration of hematite nanoparticles dried pattern of deoxyribonucleic acid from calf thymus (CT-DNA) was altered. Iron hybridized cetylpyridinium chloride was utilized for the preparation of iron oxide nanoparticles through hydrothermal method.

Experimental validation of DNA interactions with nanoparticles derived from metal coupled amphiphiles.

In the present report, a facile strategy for the synthesis of copper nanoparticles utilizing copper@cetylpyridinium chloride as the metal precursor in combination with vitamin C, was been developed. Synthesized nanoparticles (NPs) were well characterized through UV-Vis spectroscopy, dynamic light scattering (DLS), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, energy dispersive X-ray (EDX) spectroscopy, and powder X-ray diffraction (XRD). The as-obtained NPs were used for binding with deoxyribonucleic acid from calf thymus (CT-DNA).
