PHENOLS AND HYDROXYLATED BIPHENYLS AS SUSTAINABLE COMPOUNDS FOR NANOTECHNOLOGIES.

We prepared a small collection of phenols and its C2-symmetry hydroxylated biphenyls to be applied for a novel nanotechnology-based approach in biosensor building and seed dressing. Biosensor technology provides easy-to-use and effective devices for medical, environmental and agro-food analyses. Amperometric biosensors are often coated with a polymeric permselective film, usually poly-Phenylendiamines (PD), to avoid electroactive interference by reducing agents, present in the target medium. We evaluated the permselectivity, stability and lifetime of polymers electrosynthesized from naturally occurring phenylpropanoids in monomeric and dimeric forms1. Among tested compounds, poly-magnolol and poly-isoeugenol can be regarded as effective and a healthier alternatives to poly-PD film in biosensor applications2.
