Miniaturized thin-film biosensors using covalently immobilized glucose oxidase☆
Gerald Urban,Gerhard Jobst,Franz Kohl,Artur Jachimowicz,F. Olcaytug,O. Tilado,P. Goiser,Gerhard Nauer,Fritz Pittner,T. Schalkhammer,E. Mann-Buxbaum +10 more
TL;DR: In this article, a miniaturized glucose sensor by means of thin-film technology is reported, which can be placed on glass or flexible polymer substrates by using a double working electrode array for reproducibility tests or differential measurements to suppress interferences.

Stabilisation and determination of the biological activity of L-asparaginase in poly(D,L-lactide-co-glycolide) nanospheres.
TL;DR: The biological activity of L-asparaginase during preparation and storage can be improved by combining appropriate additives but concurrently the release profile is influenced by coencapsulation of the stabilisers resulting in increased first bursts.

Electrochemical glucose sensors on permselective non-conducting substituted pyrrole polymers
TL;DR: In this paper, a four-electrode electrochemical cell with an outer diameter of 2.5 mm possessing two identical working electrodes is produced by using glass sheets or Upilex foils as electrode carriers.

New microminiaturized glucose sensors using covalent immobilization techniques
E. Mann-Buxbaum,Fritz Pittner,T. Schalkhammer,Artur Jachimowicz,G. Jobst,F. Olcaytug,Gerald Urban +6 more
TL;DR: In this article, a 3-electrode miniaturized electrochemical cell with an outer diameter of 200 μm was produced by means of standard wet and dry etching procedures, which consists of a 100 nm thick titanium or Palladium sandwich layer on glass substrates isolated by a 3 μm silicon nitride film.

Metal Nano-Cluster Biosensors
TL;DR: In this paper, the authors presented the first biosensor which clearly showed a narrow reflection minima system in the red or infra-red and therefore far away from the limit exhibited by spherical gold colloids at around 600 nm.
