Lacease biosensors from bio-coatings deposited by corona plasma SPP for rutin determination

Plasma Polymerization is a well known technique for deposition of thin, solid films including biologically active compounds such as enzymes. Such bio-coating can be used in the construction of biosensors by forming the bioreceptor layer. The purpose of this work was to study the analytical performance parameters of biosensors fabricated using SPP (Soft Plasma Polymerization) for deposition of the bioreceptor layer. Experiments showed that application of SPP to fabricate the bioreceptor layer allows construction of biosensors with a linearity of response at lower concentration levels of Rutin in comparison to biosensors fabricated by conventional wet chemistry methods and, thus, higher sensitivity.
