Abstract
Phenol biosensor strips were microfabricated by screen-printing of tyrosinase containing carbon inks. The ability of the enzyme to tolerate the 2-hour firing process (at 110°C) is attributed to its organic phase activity. The resulting strips offer unmediated detection of phenolic compounds down to the 1×10−7M level. Direct assays of untreated drinking-and groundwater samples indicate great promise for field screening of phenolic compounds.Keywords
