Optical properties of water soluble CdSe quantum dots modified by a novel biopolymer based on sodium alginate.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 114 , 622-6, (2013) Water soluble CdSe quantum dots (QDs) were modified using a novel biopolymer based on the graft copolymerization of poly (acrylic acid) as a monomer onto sodium alginate as a backbone at room temperature. The obtained CdSe QDs were characterized by Fourier tr... |
