A novel core-shell gold colloid-silk fibroin (SF) bioconjugate was prepared by the protein in situ redox technique at room temperature, in which the tyrosine (Tyr) residue of the SF, having strong electron donating properties, in situ reduced Au(III) ions to Au colloids showing a stable and highly monodispersed nature.

Noble metal nanocolloids are prepared from their precursors by in situ reduction of a silk fibroin solution at room temperature without any reducing agent. The mechanism, the effects of pH and the molar ratio of the reactants on the reduction reaction are studied by UV-Vis spectroscopy. The structure of the colloids is characterized by FT-IR, TEM and AFM. According to the TEM images, the gold-silk fibroin colloid is a nanostructured bioconjugate with novel core-shell, while the silver-silk fibroin colloid tends to be congregated as clusters having more than ten nanoparticles of silver-silk fibroin. The gold colloid is highly dispersed and stable while the silver colloid is less dispersed and stable than the gold colloid.

家蚕丝素蛋白质在不同pH条件下经均相和不均相配位反应制备了Cu（Ⅱ）-丝素配合物，用可见光谱、电子自旋共振波谱（ESR）、X射线衍射（XRD）研究了其配位结构和高次结构。在碱性条件下（pH=10.60），丝素肽链主链的4个氮原子螯合Cu（Ⅱ）生成具有近似平面四方Cu（N）4结构的配合物；而在酸性条件下（pH=4.30,5.88），主要是丝素肽链的侧（端）基羧酸根键合Cu（Ⅱ）生成Cu（Ⅱ）（-COO-）（H2O）3和Cu（Ⅱ）（-COO-）2型配合物。讨论和描述了不同条件下生成的Cu（Ⅱ）-丝素配合物的高次结构。

Two soluble phthalocyanines, cobalt(II)- and iron(III)-octacarboxyphthalocyanines have been examined as catalysts for the oxidation of methanethiol and hydrogen sulphide. Under similar conditions, the cobalt phthalocyanine exhibited higher catalytic activity than the iron compound. On the other hand it was found that when the two catalysts were employed together in equal molar quantities a synergistic effect was observed. For its practical application to the removal of odours caused by methanethiol and hydrogen sulphide, the two metallophthalocyanines were used to dye viscose fibre, pretreated with a cationic agent producing a novel air-purifying material. The dyed fabric was highly effective at eliminating odours caused by these two compounds.
