(Fig. 2). When below and above of this
amount of gelatine was used in the biosensor constructiondecreases in the biosensor response were observed. These
observations resulted from formation of a porous surface
on the bioactive layer of the biosensor when 2.21 mg cm
gelatine was used and formation of a steric structure on the
bioactive layer of the biosensor when 8.84 mg cm
tine was used.
