Description
Summary:In the background that the marine cyanobacteria offer great potentials as source of fine chemicals, pharmaceuticals, biofuels, etc., in the present study the pigment, C-phycoerythrin (C-PE) extracted from the marine cyanobacterium, Phormidium tenue NTDM05 was used to synthesize CdS nanoparticles. The CdS nanoparticles thus synthesized were characterized adopting UV–Visible spectrum, Fourier transform infra-red spectrum, EDAX and transmission electron microscopy. The size of the CdS nanoparticles was found to be about 5nm. Essentially, it was found that the pigment stabilized the CdS nanoparticles. The pigments labeled CdS nanoparticles could be applied as a biolabel. [Display omitted] ► Synthesis of CdS nanoparticles with natural pigment c-phycoerythrin. ► C-PE plays an important role in the formation of CdS nanoparticles and capping them. ► The spherical shaped 5 nm sized CdS nanoparticle have been synthesized. ► This may be the first report on the pigment based synthesis of CdS nanoparticles.
