In the present work, we report the synthesis of the novel esters of indomethacin (IDMC) and an ester of reduced IDMC. For this purpose, IDMC is covalently bound by using a spacer chain to the pyrrole (Py) in the 3-position. The innovative pyrrole-indomethacin (3-Py-IDMC) derivates show no cytotoxic effects in primary calvarial osteoblasts. The designed IDMC(More)
Polypyrrole-polysaccharide thin films were electropolymerized from starting solutions containing pyrrole and a polysaccharide, namely, heparin, chondroitin-4-sulphate or hyaluronic acid. The synthesized samples showed good chemical and physicochemical properties determined by the synthesis parameters such as the current density and time. For instance, the(More)
Novel composite polypyrrole/chondroitin-4-sulphate films with cation-exchange properties were synthesized by the electrochemical polymerization of pyrrole in the presence of chondroitin-4-sulphate (CSA) sodium salt, acting as dopant anion at neutral pH. The negatively charged biomolecule was found to be permanently entrapped in the polypyrrole (PPy)(More)
Cellulose-based hydrogels, obtained by tuned, low-cost synthetic routes, are proposed as convenient gel electrolyte membranes. Hydrogels have been prepared from different types of cellulose by optimized solubilization and crosslinking steps. The obtained gel membranes have been characterized by infrared spectroscopy, scanning electron microscopy,(More)
