Layer by layer deposition strategy is well known and broadly applied [1-5]. The most popular approaches are alternating deposition of the oppositely charged organic polyelectrolytes [1, 2] or alternating deposition of polyelectrolyte and charged particles [3-5]. Only few experimets where LbL film was obtained by alternating deposition of the oppositely charged particles are known [6, 7]. According to our knowledge there are no reports on LbL conductive film composed with conductive and nonconductive particles mixture.
    The new LbL modified electrode was designed. ITO covered glass substrate was subsequently modified with the positively charged covalently bonded ionic liquid mesoporous silicate submicroparticles [8] and negatively charged sulfonated carbon nanoparticles.
    Electrochemical properties of the new modified electrode were investigated. It was found that new electrode shows accumulation properties towards ABTS. Nearly no accumulation was visible in the case of K4Fe(CN)6. One can conclude that ABTS adsorption is caused rather by the presence of carbon particles than electrostatic interactions.
    Electrochemicaly active surface development was shown with H2O2 electroreduction.
The electrode exhibits electrocatalytic properties towards NADH oxidation. New electrode has been also found as a promising support for enzyme immobilization. After laccase adsorption electrode exhibits mediatorless bioelectrocatalysis of dioxygen reduction.
