Modification of the chiral selectivity of D-glucose oxidase and L-lactate oxidase in a collagen matrix.

A chiral, biocompatible, conducting material comprising collagen I, silica gel and ferrocene was found to modify and invert, the chiral selectivity of D-glucose oxidase and L-lactate oxidase. This result may have implications as collagen matrices are widely used in drug delivery, biosensing and tissue engineering. Investigations were carried out using electrochemical methods, FTIR spectroscopy and circular dichroism.
