N‐Heterocyclic Carbene–Graphene Nanotransistor Based on Covalent Bond for Ultrastable Biosensors

Kyung Ho Kim,
Sung Eun Seo,
Seon Joo Park
et al.

Abstract: Fatal pathogenic organisms have been detected by various point‐of‐care tests (PoCTs) in clinical samples. PoCTs based on portable electrical devices are able to detect organisms in simple and rapid method. Although electrical PoCT devices show ultra sensitivity when detecting pathogens in standard samples, their industrialization has been limited due to low reproducibility, sensitivity, and specificity, resulting from nonspecific binding issues by media. In this research, a perpendicular N‐heterocyclic carbene… Show more

“…The electron irradiation experiments were performed for a series of NHC monolayers containing the imidazolium (IM) moiety to link molecules with the gold substrate, which, with only a few exceptions, is currently the most common strategy for NHC SAM formation. , , In the analyzed series of molecules the IM moiety was linked with different numbers ( n ) of benzene rings: IM Me ( n = 0), BIM Me /BIM iPr ( n = 1), and NIM Me ( n = 2). Importantly, in most of the systems analyzed here (IM Me , BIM Me , and NIM Me ) short methyl (Me) side groups of nitrogen heteroatoms were used.…”
