Popis:	Benzoxazine oligomers synthesized by a Mannich type reaction of bisphenol A, tetraethylenepentamine and formaldehyde were electrochemically crosslinked in presence of both an Os-complex modified poly(methacrylate) polymer and glucose oxidase. The crosslinking led to the formation of a biocatalytically active layer on an electrode surface exhibiting a swelling process after immersion in an electrolyte solution containing glucose most likely due to the local decrease of the pH value upon glucose oxidation. Optimization of the poly(benzoxazine) to Os-complex modified poly(methacrylate) ratio was performed leading to a reagentless glucose biosensor with improved stability.
