- synthesis of metallic NPs, using biopolymers such as chitosan can eliminate the need to use capping agents [56][86][99]. Catalysis: Selecting proper catalytic reactions can enhance the overall efficiency of the process by decreasing the activation energy and increasing product selectivity. These advantages
- stable in NaCl solution. However, they are aggregated in the presence of NaNO3 or NaH2PO4 [141]. Laudenslager et al. used CTS and carboxymethyl chitosan (CMC) as stabilizing agent for production of Pt, Au and Ag NPs. These two biopolymers gave similar size distributions, while CMC showed higher

- structure formation of inorganic components in an aqueous environment. Accordingly, composites made of inorganic solids (i.e., calcium phosphate or carbonate) and biopolymers are formed. Furthermore, the resulting combination of inorganic and bioorganic components yields biominerals with unique
Biopolymer colloids for controlling and templating inorganic synthesis

- Laura C. Preiss Katharina Landfester Rafael Munoz-Espi Max Planck Institute for Polymer Research, Ackermannweg 10, 55128 Mainz, Germany 10.3762/bjnano.5.222 Abstract Biopolymers and biopolymer colloids can act as controlling agents and templates not only in many processes in nature, but also in a
- wide range of synthetic approaches. Inorganic materials can be either synthesized ex situ and later incorporated into a biopolymer structuring matrix or grown in situ in the presence of biopolymers. In this review, we focus mainly on the latter case and distinguish between the following possibilities
- : (i) biopolymers as controlling agents of nucleation and growth of inorganic materials; (ii) biopolymers as supports, either as molecular supports or as carrier particles acting as cores of core–shell structures; and (iii) so-called “soft templates”, which include on one hand stabilized droplets

Exploring the complex mechanical properties of xanthan scaffolds by AFM-based force spectroscopy
Beilstein J. Nanotechnol. 2014, 5, 365–373, doi:10.3762/bjnano.5.42
- ; Introduction In general, a scaffold is composed of small units including sheet-like, cylinder-like, tube-like, sphere-like and sponge-like structures. Scaffold structures formed by various biopolymers have attracted more and more attention due to their potential applications in tissue engineering [1], such as

- prepared by evaporative casting. All composite films displayed sensitivity to water vapour, but MWNT films were more sensitive than SWNT films. Keywords: biopolymers; carbon nanotubes; carrageenan; composite materials; conductivity; mechanical; rheology; Introduction Carbon nanotubes (CNTs) have
- their high surface energy and van der Waals interactions [3][5][6][7]. To overcome this issue, a diverse range of molecules have been used to aid the dispersion of CNTs in aqueous media, such as surfactants, polymers and biopolymers [8][9][10][11][12][13][14][15][16]. Well known examples of surfactants
- and polymers include, sodium dodecyl sulfonate, Triton X-100 and polystyrene sulfonate [17][18][19][20][21][22][23][24]. In addition, it has been established that biopolymers such as gellan gum, xanthan gum, gum arabic and iota-carrageenan are effective for the dispersion of CNTs in aqueous solutions
