“…Conducting polymers (CPs) have been progressively reported in the literature as promising candidates in a wide range of applications such as electrochemical actuators, organic vapor sensors, flexible light emitting diodes, organic photovoltaic cells, biologic sensors and batteries (1)(2)(3)(4)(5)(6)(7)(8)(9). In all of applications involving CPs, the charge storage capacity represents a critical parameter that must be optimized in order to develop more efficient devices.…”

We report the electrochemical synthesis and characterization of hybrid structures composed by hollow nanotubes of polypyrrole and core-shell composites of multi-walled carbon nanotubes (MWCNTs) coated by polypyrrole (PPy). The synthesis of these systems is critically dependent on relative concentration of carbon nanotubes (introduced as a template for polymerization) and affects the level of conductivity of media, the diameter and relative roughness of synthesized nanotubes. The competition induced by polymerization on the surface of different templates (aggregates of methyl orange and MWCNT) allows that smooth structures can be obtained, minimizing the synthesis of granules of polypyrrole, in a process that affects the morphology, thermal and electrical properties of synthesized materials. As a result, the impedance of mixed composite is lower than the other obtained for each system (MWCNT and hollow nanotubes of PPy), in an indication that synergistic interaction is favored during the synthesis.

“…Peak at 1413 cm À1 corresponds to CeN vibration, that at 1047 cm À1 corresponds to CeH vibration and that at 1579 cm À1 corresponds to G band. Remaining peaks are due to ring deformation associated with polarons (radical cation) and bi-polarons (di-cation) [31], Fig. 2(A) (b) shows the Raman spectra of NC.…”

“…They are formed by randomly dispersion of CNTs with insulating polymeric matrices such as granular Teflon 119 , chistosan 120 , polystyrene 121 , polysulfone 122 and epoxy [123][124] or by their incorporation into a silicate gel matrix [125][126] ; or with conductive polymers such as polypyrrole 127 and polyaniline 128 which can be fabricated by chemical or electrochemical polymerization. 43,125,[129][130] Irrespective of the nature and the way in which the composite is built up, these matrices are important for providing robustness to the CNT platform and at the same time for facilitating the analyte trapping which can result quite advantageous for some applications in the (bio)chemical sensing field.…”

Within this new field of nanobiotechnology, the area of (bio)sensors is the most developed and the one which has the highest potential for short-term applications. In this context, (bio) sensors based on electrochemical principles stand out due to their marked advantages in terms of simplicity, robustness, low cost, miniaturization capability and integration to devices.These sensors are becoming very attractive for rapid and simple diagnostic, in fields such as biotechnology, clinical and environmental research.Historically, carbon has been a widely used and practical electrode material due to its desirable properties for electrochemical applications. Available in a variety of structures, carbon electrodes provide, in general, good electrical conductivity, high thermal and mechanical stability, a wide operable potential window with slow oxidation kinetics and, in many cases, electrocatalytical activity. On top of that, they are recognized as versatile and easy handling materials, and also praised by their rich surface chemistry which has been exploited to influence surface reactivity. Thus, The third and last part of the study is focused on exploiting the semiconductor character of carbon nanotubes for sensor technology by using a field effect transistor XXIX configuration (FET). The CNT-FET device has been optimized for operating in liquid environment by performing passivation protocols. This, together with the use of bifunctional pyrene linkers for the immobilization of the aptamers, has allowed sensitive electronic detection of protein/aptamer interaction. Additionally, we were also able to follow up protein adsorption and protei...
