文摘

Silicone containing amphiphilic co-networks are used as immobilisation matrix for ABTS (chromophor) and horseradish peroxidase. The good gas diffusion properties as well as the good immobilisation properties of the silicone containing APCNs, reffered to as silicone hydrogels, makes this type of sensors suitable for fast real-time gas detection. Detection of 1 ppm of gaseous peroxide (used as explosive or precursor) is feasible within seconds.
