Several physicochemical analytical methods were used to study aqueous solutions and hydrogels based on L-cysteine and silver nitrate. It was found that anions played a decisive role in forming the threedimensional gel-network in dilute silver-cysteine solutions. The ability to use silver-cysteine solutions and hydrogels to prepare bactericidal fibers and fabrics was examined. © 2011 Springer Science+Business Media, Inc.

Modern suturing materials are developed with a focus on the requirements of surgeons for the optimum mechanical characteristics; interchangeability; compatibility; safety; a lack of allergic, teratogenic, and cancerogenic action in vivo; and a lack of capillary action. Biologically active (BA) thread with a complex action that was prepared by impregnating polyamide or polyester thread-base with a modified composition based on the biopolymer chitosan and including the antibacterial preparation ciprofloxacin and the germanium-containing preparation Astragerm-C was selected for the studies. The goal was to study the effects of the selected modification method and the composition of the modifier on the functional properties of a new surgical suturing material. It was shown that the produced surgical suturing material had improved functional properties that comply with modern requirements.

A method for decomposing polyamide threads and polyester fabric treated with the germanium-containing preparations Panaxel and Astrogerm-C was developed. The method extracted Ge most completely in order to determine it by spectrophotometry for subsequent development of a standard method and inclusion of it in on-line monitoring of the raw material, intermediate solutions, and finished product from manufacturing of medical materials. Methods for mineralization of the raw material and polymeric matrix by wet ashing and thermal combustion were investigated. It was found that thermal treatment of biologically active preparations resulted in significant losses of Ge. Germanium could be extracted quantitatively by chemical mineralization only with preliminary oxidation or treatment by a mixture of strong oxidizing acids (nitric, sulfuric, perchloric). Methods for mineralization of the polymeric matrix were developed. It was shown that the presence in the polymeric matrix of antimony, which is used as a catalyst for polyester production, must be taken into account in determining Ge in polyester fibers. © 2011 Springer Science+Business Media, Inc.
