“…45 Silver has high affinity for nitrogen, lower for oxygen and much lower for carbon. 26 Nitrogen atoms have free electron doublets that are able to react with silver cations, because they have lone electron pairs in orbitals. Oxygen is able to attract the silver via electrostatic interactions, but the attraction is weaker 50 than in the case of nitrogen.…”

“…7 The presence of chitosan should then positively inuence binding of silver onto the dressing, since chitosan is able to chelate metals and silver has higher attraction to nitrogen than to oxygen. 6,26 In another words, one modication step should advantageously inuence the next one. Silver in the form of AgCl precipitate was chosen purposely because of the sufficient antibacterial activity and lower toxicity than Ag + ions.…”

The treatment of wounds often deals with bacterial infections thus complicates healing. Our aim was to prepare cellulose wound dressings with antibacterial properties. Cellulose dressing was exposed to argon plasma discharge, impregnated with chitosan and then silver chloride particles were precipitated in situ on the dressing´s surface. The effect of plasma treatment on both the chitosan impregnation and silver chloride precipitation was studied, together with the antibacterial properties of the prepared dressings. 10 The materials were characterized by optical microscopy, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), goniometry, absorption atomic spectroscopy (AAS) and zeta potential measurement. The antibacterial potency of the dressings was assessed using environmental bacterial strains of Escherichia coli and Staphylococcus epidermidis. Plasma treatment had a positive effect on both chitosan impregnation and the silver chloride precipitation. The antibacterial tests performed on 15 these wound dressings exhibited growth prevention of the two representative strains of Gram-positive and Gram-negative bacteria. These results are of medical interest. 65

“…Functionalization by binding a series of functional groups onto the CNT sidewalls by means of chemical reactions or physical interactions is a common practice to enhance the solubility and increase the selectivity of CNTs [76] and the majority of IR and FT-IR applications have been aimed at characterizing such surface modifications [77]. Examples of this application include the use of FT-IR to confirm the functionalization of MWCNTs with aminobenzothiazole [78], tris(2-aminoethyl) amine [79], ethylenediamine [80], and chitosan [81], among others.…”

“…Therefore, Raman spectroscopy is one of the most promising techniques for characterization and impurity evaluation of CNTs (character of CNTs, due to the presence of acidic oxygen and diverse oxygen containing groups, can be ascertained by Boehm titration using different bases of various strengths (NaHCO 3 , Na 2 CO 3 , NaOH and NaOC 2 H 5 )(147). The modifications and functionalizations on the surface of CNTs can also be confirmed with some other spectroscopic procedures such as nuclear magnetic resonance (NMR)(148) and fourier transform infrared spectroscopy (FT-IR)(149). The surface modifications (oxidation and functionalization) of CNTs made them convenient for the solubilities in organic and aqueous solvents.…”

Sample preparation is the backbone of any analytical procedure; it involves extraction and pre-concentration of the desired analytes; often at trace levels. The present article describes the applications of nanomaterials (carbon based inorganic and polymeric materials) in miniaturized extraction such as solid phase micro-extraction, stir-bar sorptive extraction, liquid phase micro-extraction, and dispersive liquid phase micro-extraction in the analyses of aqueous samples. The nanoparticles used for micro-extractions are discussed on the basis of their chemical natures. The synthetic route and the preparation of nanomaterials are described along with the optimization strategies for microextraction. A comparison between the conventional materials and nanomaterials for micro-extraction is proposed.The key roles of the nanomaterials for the micro-extraction of different analytes such as drugs, pesticides, polycyclic aromatic hydrocarbons, proteins and peptides from aqueous samples are reported. The use of nanomaterials, combined with miniaturized micro-extraction techniques, proved to be highly promising for sample preparation of various matrices with analytes at trace levels.
