“…14,15 While the photonic and optoelectronic properties of 2D materials are being intensively investigated, 16,17 their implementation to biosensing and biomedical applications is limited thus far, although some reports have emerged recently. 18,19 Given that these materials exhibit a weak interlayer bonding through the van der Waals interaction, solvents and mild agitation through sonication allows layer separation into monolayer or few-layer nanomembranes from the bulk crystal. 20 To advance the utility of these materials for biosensing and biomedical applications, the biocompatibility of 2D graphene and MoS 2 with both mouse embryonic fibroblasts (STO) and human esophageal fibroblasts (HEF) cell lines was explored, for photodetector applications with potential for retinal prostheses.…”

An inkjet printed, biocompatible, heterostructure photodetector is described that was constructed using inks of photo-active molybdenum disulfide (MoS 2 ) and electrically conducting graphene which facilitated charge collection of the photocarriers. The importance of such devices stems from their potential utility in age-related-macular degeneration, which is a condition where the photosensitive retinal tissue degrades with aging, eventually compromising vision. The absence of effective therapeutic remedies for patients with this disorder has motivated the development of such devices to restore some degree of visual function. Inkjet printed, flexible prosthetic devices offer design simplicity where additive manufacturing can enable large format, low-cost arrays. The biocompatible inkjet printed two-dimensional heterojunction devices were photoresponsive to broadband incoming radiation in the visible regime, and the photocurrent I ph scaled proportionally with the incident light intensity, exhibiting a photoresponsivity R~0.30 A/W. This is 10 3 times higher compared to prior reports, and detectivity D was calculated to be~3.6 × 10 10 Jones. Straindependent measurements were also conducted with bending, indicating the feasibility of such devices printed on flexible substrates. Drop cast and printed CT-MoS 2 inks were characterized using techniques, such as Raman spectroscopy, photoluminescence measurements and scanning electron microscopy. Both mouse embryonic fibroblast and human esophageal fibroblast were used for the biocompatibility analysis for inks drop cast on two types of flexible substrates, polyethylene terephthalate and polyimide. The biocompatibility of inks formed using two-dimensional graphene and MoS 2 on polyimide substrates was extremely high, in excess of 98% for mouse embryonic fibroblast.

Fluorographene is an excellent precursor for the synthesis of graphene derivatives. Relative to pure graphene, fluorographene possesses higher reactivity and, in comparison with graphene oxide, is also homogenous in composition, which enables the preparation of well-defined materials. Recently, it has been shown that several graphene derivatives can be synthesized from fluorographene, thus yielding various products such as graphene acid or alkylated graphene. This study focuses on the hydrogenation of fluorographene by using various hydrogenation reactions, including the use complex hydrides and solvated electrons in different media. In addition, a comparison of these reactions shows that fluorinated graphite has significantly lower reactivity than fluorographene. The conversion rates of these reactions are higher when fluorographene is used relative to fluorographite. These reactions can be used to tune the hydrogen/fluorine composition on a graphene backbone.

Graphitic carbon nitride (g-C 3 N 4 ) has attracted considerable attention due to its special structure and properties, such as its good chemical and thermal stability under ambient conditions, low cost and non-toxicity, and facile synthesis. Recently, g-C 3 N 4 -based sensors have been demonstrated to be of high interests in the areas of sensing due to the unique optical, electronic and catalytic properties of g-C 3 N 4 . This review focuses on the most salient advances in luminescent sensors based on g-C 3 N 4 , chemiluminescence, cataluminescence and electrochemiluminescence methods are discussed. This review provides valuable information for researchers of related areas and thus may inspire the development of more practical and effective approaches for designing two-dimensional (2D) nanomaterial-assisted luminescent sensors.
