“…For the nanoparticle synthesis in the second method, polysaccharides such as native starch (Rodriguez et al 2008), soluble starch (Chairam et al 2009;Li et al 2007;Ma et al 2009;Radhakrishnan et al 2007;Vigneshwaran et al 2006;Wei et al 2004), and CMC Liu et al 2011a;Yu et al 2009;Zheng et al 2009a) have been shown to be good stabilizers. Polysaccharides can form complexes with divalent metal ions due to their high number of coordinating functional groups (hydroxyl and glucoside groups) (Taubert and Wegner 2002) and present dynamic supramolecular associations facilitated by inter-and intramolecular hydrogen bonding, which can act as templates for metal nanoparticle growth (Raveendran et al 2003).…”

Starch as a biopolymer directly extracted from nature has received much attention in recent years due to its strong advantages such as low cost, wide availability, renewability, and total compostability without toxic residues. Starch-based materials always display properties that are less satisfactory than those of traditional polymer materials, which can be ascribed to the inherent characteristics of starch. To make such materials to be truly competitive and to widen its applications, the development of starch-based nano-biocomposites could be a promising solution. This chapter provides the fundamental knowledge related to starch-based nano-biocomposites as well as the most recent developments in this area. Various types of nanofillers that have been used with plasticized starch are discussed such as montmorillonite, cellulose nanowhiskers, and starch nanoparticles. The preparation strategies for starch-based nano-biocomposites with these types of nanofillers and the corresponding dispersion state and related properties are also largely discussed.

“…The hydroxyl groups of the starch act as the coordination site for the release of the metal ions and hence control the chemical reaction rate of M 2+ and Se 2-to produce MSe. These hydroxyl groups also act as passivating centres for stabilisation and solubility of the as-synthesized nanoparticles in water, while the free aldehyde group on one end of a starch polymer could also act as conjugation site for further functionalization which makes it easier for its biological applications (Raveendran et al, 2003;, Mishra et al, 2009;Rodriguez et al, 2008).…”

“…Recently, biopolymers, such as chitosan [4][5][6][7], alginate [8][9][10][11] and starch [12][13][14][15][16][17][18][19][20][21][22][23][24] have been introduced as capping agents and/ or matrices for semiconductor, metal and semiconductorsemiconductor core-shell nanoparticles. Because macromolecular chains of these biopolymers possess a large number of hydroxyl groups, they can complex well with metal ions, which further enables a good control of size, shape and dispersion of the nanoparticles formed.…”
