Electrochemically Induced Formation of Surface-Attached Temperature-Responsive Hydrogels. Amperometric Glucose Sensors with Tunable Sensor Characteristics

Autor: Katja Pohl, Wolfgang Schuhmann, Johanna Bünsow, Diethelm Johannsmann, Anne Enzenberg

Publikováno v: Electroanalysis. 22:978-984

Employing thermally responsive hydrogels, the design of an amperometric glucose sensor is proposed. The properties of the biosensor can be modulated upon changing the temperature. Homo- and copolymers of N-isopropylacrylamide (NIPAm) and oligo(ethyle

Electrochemically Induced RAFT Polymerization of Thermoresponsive Hydrogel Films: Impact on Film Thickness and Surface Morphology

Autor: Diethelm Johannsmann, Johanna Bünsow, Martin Mänz, Philipp Vana

Publikováno v: Macromolecular Chemistry and Physics. 211:761-767

Thin hydrogel films of the thermoresponsive polymer poly(N-isopropylacrylamide) (pNIPAm) were prepared by electrochemically triggered reversible addition-fragmentation chain transfer (RAFT) polymerization. Two different RAFT agents were employed, whi

Preparation of Hydrogel-Silica Composite Films by Electrochemically Triggered Deposition

Autor: Diethelm Johannsmann, Johanna Bünsow, Judith Petri

Publikováno v: Macromolecular Symposia. :250-256

The electrochemical formation of hybrid films containing both a polymer and porous silica was performed in two different ways. In both cases, the deposition of the inorganic oxide was triggered by an electrochemical pH modulation in front of an elect

Production of Polyacrylic Acid Homo- and Copolymer Films by Electrochemically Induced Free-Radical Polymerization: Preparation and Swelling Behavior

Autor: Diethelm Johannsmann, Johanna Bünsow

Publikováno v: Radical Polymerization: Kinetics and Mechanism, Volume 248

Films of polyacrylic acid hydrogels were produced on a conducting substrate by means of electrochemically initiated polymerization (EIP). An electrochemical quartz crystal microbalance was used to monitor film growth in situ. Homopolymer and copolyme

Electrochemically produced responsive hydrogel films: influence of added salt on thickness and morphology

Autor: Johanna Bünsow, Diethelm Johannsmann

Publikováno v: Journal of colloid and interface science. 326(1)

We report on electrochemically prepared hydrogel layers of poly-N-isopropylacrylamide (pNIPAm) and on the influence that the supporting electrolyte has on their thickness and morphology. Ions that are destabilizing in the Hofmeister sense increase th
