Current Trends In Using Carbon Pastes and Some Future Prospects 

Before stepping into the realm of chemically and biologically modified carbon pastes with all their hitherto existing configurations and variants, it is useful to overview the latest advances with carbon pastes as such, which can be accomplished with the aid of a properly selected collection of newly appearing articles [90-100]. 

Such a brief summary can be started with a brand new review [90] that pursues the recent achievements with new carbon pastes made of alternate carbons and binders for example, graphite powder-based solgel electrodes. Another review article then reflects the still stronger position of solid-state analysis herein, in a new renaissance of solid-phase electrochemistry with electroactive carbon paste electrodes, CPEEs [91]. 

For everyone who has watched the field from the very beginning, it is a pleasure to see a couple of reports from Japanese authors [91, 92], concerning the successful revival of the already introduced dropping carbon electrode, DCE [1-3]. Reportedly, the new prototype was wholly functional for its primary purpose - polarographic oxidations in aqueous solutions - when a three-component mixture of graphite, dioctyl phthalate, and triiodomethane acted as the true DCE with a periodically renewable surface. 

Of continuing interest are the new forms of carbon for example, nanoparticles [93] and, in particular, graphene [94-97] whose momentary popularity is reminiscent of the boom of CNTs in the late 2000s. Similarly, also ILs, ILs, still attract considerable attention, and even now some authors come with completely new theoretical models [98]. Besides these main areas, other applications can be traced, such as the case of a new CP-array proposed as the scanning tip(s) for electrochemical microscopy [99].
