Synthesis and characterization of CdS nanoparticles using C-phycoerythrin from the marine cyanobacteria

Abstract: 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. [Copyright &y& Elsevier]
