“…The smaller and uniform the reaction cavity is, the smaller the dimension and narrower the size distribution of the resulting NPs. Different types of polymer-based agents have been investigated for preparation of metal and non-metal particles [26][27][28][29][30][31]. Metal NPs, semiconductors, inorganic oxides, and quantum dots synthesis were also investigated, especially in the confined space of surfactants, inorganic templates, and polymeric stabilizing agents [32][33][34][35].…”

This chapter summarizes the basic information about elementary characteristics and technology of preparation of noble metal nanoparticles. The introduction gives some basic information on the history of development in this area, especially in terms of dimensionality of metal nanostructures and their possible applications.The first subsection is devoted to the preparation and characterization of "u, "g, Pt, and Pd nanoparticles NPs , which were synthesized by direct metal sputtering in liquid propane-, , ,-triole glycerol . This method provides an interesting alternative to time-consuming, wetbased chemical synthesis techniques. Moreover, the suggested technique allows targeted variation of metal nanoparticle size, which is demonstrated in detail in case of "uNPs by variation of capturing media temperature. Nanoparticle size and shape were studied by transmission electron microscopy and dynamic light scattering. Optical properties of nanoparticle solution were determined by measuring its UV-Vis spectra. Concentration of metal nanoparticles in prepared solutions was determined by atomic absorption spectroscopy. "ntibacterial properties were tested against two common pollutants Escherichia coli, a Gram-negative bacteria, and Staphylococcus epidermidis, a Gram-positive bacteria . In the presence of "g nanoparticles, the growth of E. coli and S. epidermidis was completely inhibited after h. "ny growth inhibition of E. coli was observed neither in the presence of smaller -nm, "uNP -nor bigger -nm, "uNP -"uNPs during the whole examination period. "uNP -, but not "uNP -, was able to inhibit the growth of. S epidermidis. We also observed significant difference in biological activities of Pt and PdNPs. More specifically, PdNPs exhibited considerable inhibitory potential against both E. coli and S. epidermidis, which was in contrast to ineffective PtNPs. Our results indicate that "g, Pd, and partially "uNPs have high potential to combat both Gram-positive and Gram-negative bacterial strains.The second subsection describes the effort to anchor metal nanoparticles onto polyethyleneterephthalate PET carrier. Two different procedures of grafting of polymeric carrier, activated by plasma treatment, with "u and "gNPs are described. In the first procedure, the PET foil was grafted with biphenyl-, -dithiol "PD and subsequently with "u and "gNPs. In the second one, the PET foil was grafted with "u and "gNPs previously coated by the same "PD. X-ray photoelectron spectrosco-© 2015 The Author(s). Licensee InTech.

“…Hydrogels have a wide range of applications in controlled drug delivery systems, tissue engineering, artificial organs in biotechnology, the recognition of certain bio-molecules and so on [15,16]. These materials can absorb large amounts of water and swell due to the existence of the hydrophilic groups (-OH, -COOH, -NH 2 , -CONH 2 , and -SO 3 H) in their structures [16,17].…”

“…Additionally, they are inherently environmentally benign and are chemically modifiable [1][2][3]. As hydrogels are regarded as smart materials due to their ability to sense pH [4], temperature [5], electrical and magnetic fields [6][7][8], etc. in their milieu, recently new and versatile tasks have been assigned to their micron and nano sized particles [7,8].…”
