“…Amorphous carbon (a-C) and, especially, its high sp 3 bonded carbon form, known as tetrahedral amorphous carbon (ta-C), is a promising electrode material owing to its several unique electrochemical properties, such as chemical inertness and resulting wide potential window as well as low background current. Thus, ta-C has been used in many electroanalytical applications ranging from detection of biomolecules [1][2][3][4] to trace analysis of heavy metals [5]. The basic electrochemical properties and response of ta-C to several redox systems have also been investigated [6][7][8][9] and recently reviewed [10].…”

Connection between the physicochemical characteristics of amorphous carbon thin films and their electrochemical propertiesConnecting a material's surface chemistry with its electrocatalytic performance is one of the major questions in analytical electrochemistry. This is especially important in many sensor applications where analytes from complex media need to be measured. Unfortunately, today this connection is still largely missing except perhaps for the most simple ideal model systems. Here we present an approach that can be used to obtain insights about this missing connection and apply it to the case of carbon nanomaterials. In this paper we show that by combining advanced computational techniques augmented by machine learning methods with x-ray absorption spectroscopy (XAS) and electrochemical measurements, it is possible to obtain a deeper understanding of the correlation between local surface chemistry and electrochemical performance. As a test case we show how by computationally assessing the growth of amorphous carbon (a-C) thin films at the atomic level, we can create computational structural motifs that may in turn be used to deconvolute the XAS data from the real samples resulting in local chemical information. Then, by carrying out electrochemical measurements on the same samples from which x-ray spectra were measured and that were further characterized computationally, it is possible to gain insight into the interplay between the local surface chemistry and electrochemical performance. To demonstrate this methodology, we proceed as follows: after assessing the basic electrochemical properties of a-C films, we investigate the effect of short HNO3 treatment on the sensitivity of these electrodes towards an inner sphere redox probe (ISR) dopamine (DA) to gain knowledge about the influence of altered surface chemistry to observed electrochemical performance. These results pave the way towards a more general assessment of electrocatalysis in different systems and provide the first steps towards data driven tailoring of electrode surfaces to gain optimal performance in a given application.

“…1 However, most of the SERS substrates lack long-term stability due to the instability of metal nanostructures deposited on surfaces and/or due to the intrinsic nature of the substrates themselves. 1 In this context, diamond, [2][3][4][5] SiC [6][7][8][9] and diamond-like-carbon (DLC) [10][11][12][13] thin films owing to their excellent intrinsic nature (electronic and mechanical properties, chemical stability/inertness and biocompatibility) that includes the capability for bio-sensing can be promoted as excellent SERS substrates. Moreover, the well-established microelectronic device fabrication technologies can be easily applied to these thin films to fabricate real-time SERS based bio-sensing devices (for example metal-insulator-semiconductor type devices).…”

In the recent past surface enhanced Raman scattering (SERS) based bio-sensing has gained prominence owing to the simplicity and efficiency of the SERS technique. Dedicated and continuous research efforts have been made to develop SERS substrates that are not only stable, durable and reproducible but also facilitate real-time bio-sensing. In this context diamond, β-SiC and diamond-like-carbon (DLC) and other related thin films have been promoted as excellent candidates for bio-technological applications including real time bio-sensing. In this work, SERS activities of nanodiamond, nano-β-SiC, DLC, thermally annealed diamond thin film surfaces were examined. DLC and thermally annealed diamond thin films were found to show SERS activity without any metal nanostructures on their surfaces. The observed SERS activities of the considered surfaces are explained in terms of the electromagnetic enhancement mechanism and charge transfer resonance process.
