The effect of adding finely divided hydroxyapatite (HAp) powder to glass-polyalkenoate cements has been studied. Two different glasses were used in cement formation, an oxide and a fluoride glass. Cements were prepared at a powder:liquid ratio of 2:1, higher ratios being unattainable because of the

β¦ Synopsis
The direct incorporation of proteins and other macromolecules into conductive, electroactive polymers provides a simple means by which a range of new materials can be produced. In this work we have demonstrated that the use of electrocatalysts, such as Tiron, and molecular carriers, such as surfactants or colloids, can facilitate such direct incorporation processes. In order to characterise the polymer after protein incorporation, amino acid analysis and an enzyme-linked immunosorbent assay were employed.
