The influence of surface morphological treatments of ITO on the performances of inkjet printed, enzyme-based biosensors
No full textThe utilization of semiconducting and conducting polymers for the fabrication of computer-assisted printable-on-demand electrodes (the so-called “biopolytronics” concept) is a very interesting field of investigation for the realization of third generation bioelectronic devices such as biosensors, biofuel cells,.... In this line, we studied in the last years fully inkjet printed glucose oxidase (GOD)-based electrode, realized over ITO substrates [L. Setti, A. Fraleoni-Morgera, B. Ballarin, A. Filippini, D. Frascaro, C. Piana, Biosens. Bioel., 2005, 20, 2019; L. Setti, C. Piana, S. Bonazzi, B. Ballarin, D. Frascaro, A. Fraleoni-Morgera, S. Giuliani, Anal. Lett., 2004, 37, 1559]. For enhancing the performances of these devices a deeper understanding of the phenomena of electronic transfer between inorganic electrodes such as ITO, and organic materials able to conduct electrical currents, such as for example PEDOT:PSS, is needed.
In this view, we realized surface modifications of ITO at a nano-scale, and we investigated the effect of such a treatment over the performances of inkjet printed GOD-based electrodes. In particular, investigations over the ITO surface morphology (AFM, white light interferometer, SEM, etc) and electrical characteristics (sheet resistance) have been carried on, and related to the performances of devices fabricated and tested. Together with an overview of the technologies used for the realization of biological and electronic inks, as well as for printing enzyme-based electrodes, are reported
NOTA BENE: a metà 2003 ho cambiato cognome, aggiungendo il cognome "Morgera" a quello "Fraleoni". Il mio attuale e corretto cognome è quindi Fraleoni Morgera, ma fino a metà 2003 i miei articoli e contributi a congressi sono pubblicati con il solo cognome "Fraleoni". Ho inserito il mio attuale cognome "Fraleoni Morgera" in questo articolo poiché altrimenti il sistema non mi lascia inserire la pubblicazione. Per cortesia leggete il mio nome in questo articolo come “Fraleoni A”, e considerate che in caso di controlli sui motori di ricerca per trovare tutti i miei lavori indicizzati dovete ricercare il cognome "Fraleoni" come autore, e non "Fraleoni Morgera". Quest’ultima ricerca riporterebbe solo 24 delle mie 31 effettive pubblicazioni. PLEASE NOTE: around the middle of 2003 I changed my family name, adding the surname “Morgera” to “Fraleoni”. My current and correct family name is the “Fraleoni Morgera”, but until half of 2003 my scientific production was signed only as “Fraleoni”. I inserted my current family name “Fraleoni Morgera” in this contribution because otherwise the system does not allow me to insert any further publication data. Please read my author name only as “Fraleoni A”, and consider this fact in case of checks using the main search engines, where if you want to find all of my indexed works you must search for “Fraleoni” as author, instead of “Fraleoni Morgera”. This latter search would recover only 24 publications out of my actual 31 ones.

No full textFast Fabrication of Large-Area, Nanostructured Arrays from Polymers or Carbon Nanotubes by Wet-Processing
No full textA novel, fast, and low-cost method for fabricating large-area arrays of organic-material-based filamentary nanostructures is presented. The technique, auxiliary solvent-based sublimation-aided nanostructuring (ASB-SANS), only takes minutes and exploits a templating matrix easily removable by sublimation. Proof-of-concept patterns fabricated out of poly(methylmethacrylate) (PMMA) and carbon nanotubes (CNTs) are demonstrated
Overview of Small Scale Electric Energy Storage Systems suitable for dedicated coupling with Renewable Micro Sources
No full textRenewable Micro Sources (RENMSs) will strongly contribute to the accelerating electrification trend currently ongoing. Furthermore, the upcoming mass electrification of automotive, with the related pulverized, but numerically important, electricity storage potential, suggests to start considering how to guarantee a stable and sustainable grid power. In this frame, it is interesting to consider the possibility to couple to each RENMS a dedicated Small Scale Electrical Energy Storage System (SS-EESS), so to be able to dispatch out of the RENMS a grid-compliant RENMS-produced power. An overview of SS-EESSs is hence hereby given, under the points of view of their current main technical features and their prospected costs. It is found that mechanical-based systems like Small Scale Compressed Energy Storage and Flywheels are interesting options for RENMS/SS-EESS dedicated coupling, although fast technological progress in the field of SS-EESSs and the emergence of a clear trend towards joining more energy storage principles (like batteries-supercapacitors assemblies) will
likely change the landscape of this field in the next years. In this view, further studies over dedicated coupling of SS-EESSs and RENMSs could help to avoid difficulties in dealing with
exploding electricity storage problems in the next years
