AB  - Silver nanoparticles were synthesized in a chitosan biopolymer by an in situ green chemical procedure. using D-glucose as the reducing agent. The reaction intermediates (silver-chitosan complexes) as well as the obtained nanocomposites were investigated using transmission electron microscopy, UV-vis, FTIR and photoluminescence spectroscopy. The theoretical analysis of the UV-vis absorption of the Ag-chitosan complexes suggested that the significant contribution to the complex spectrum arises from clusters of silver containing 4-9 atoms. The absorption spectrum of the nanocomposite exhibited a strong surface plasmon resonance band at 406 nm. The photoluminescence behavior of the pure chitosan, the silver-chitosan complexes and the nanocomposites were discussed in terms of morphology and silver weight content. (C) 2010 Elsevier Ltd.

AB  - A synthetic procedure for the encapsulation of cadmium selenide (CdSe) nanoparticles in a sago starch matrix is introduced. The nanocomposite was investigated using structural, spectroscopic and thermal, methods. TEM micrographs of the nanocomposite showed spherical CdSe particles of 4-5 nm in size coated with a biopolymer layer. The absorption edges of both the aqueous solution and the thin film of the CdSe-starch nanocomposite were shifted toward lower wavelengths in comparison to the value of the bulk semiconductor. Infrared measurements revealed that the interaction of CdSe nanoparticles and starch chains takes place via OH groups. Although the onset of the temperature of decomposition of CdSe-starch nanocomposite is lower than that of the pure matrix, thermogravimetric analysis also showed that introduction of CdSe nanoparticles significantly reduced starch degradation rate leading to high residual mass at the end of the degradation process.
