“…The result agreed well with that by the DPD method, suggesting the potential application of the new sensing system in drinking water quality monitoring [246]. Some other CDs were found to have the similar response toward the free chlorine, through the same PL quenching mechanism [247].…”

Carbon based dots (CDs) composed of sp 2 carbon structures and surface functional groups are a new kind of carbon nanomaterials, exhibiting unique luminescent properties due to the quantum confinement and edge effects. This chapter introduces CDs in detail from their synthetic strategies, morphological and structural characteristics, luminescent properties and mechanisms, and sensing applications. The synthesis methods are summarized as "top-down" and "bottomup" approaches. Luminescent properties discussed include photoluminescence, upconversion luminescence, chemiluminescence, electrochemiluminescence. Sensing applications mainly refer to the chemical and biological sensors based on the luminescent properties of CDs. This chapter provides an overview of the research field and gives future perspectives for developing the exciting materials.

“…It could attribute to the homogeneous surface structures and size of S-doped C-dots. 27 In our research, it is observed that the photoluminescence lifetime of the as-prepared S-doped Cdots is 11.26 ns ( Figure S3). 80 The fluorescence quantum yield for the as-prepared S-doped C-dots is determined by calibrating against quinine sulfate in 0.1 M H 2 SO 4 solution (Figure 2(e)).…”

“…Enzymelinked immuno sorbent assay (ELISA) and confocal laser scanning microscopy were further used to evaluate gene transfection and effects of cellular uptake inhibition, respectively. Compared with previous reports in which QDs were mostly investigated using their luminescent properties and applications in bioimaging [9,10,18], sodium alginate-derived CQDs in this study not only show low toxicity and excellent biocompatibility, but also act as both an effective gene vector and a fluorescent probe without additional modifications. Altogether, the findings will provide a new source for CQDs generation and solid evidence for the application of CQDs as an effective non-viral gene vector and bioimaging probe.…”

“…Photoluminescent carbon quantum dots (CQDs), as a newcomer from the carbon nonmaterials family, have been gathering considerable attention in the nanotechnology field due to their low http toxicity, excellent biocompatibility, strong fluorescence, stable photoluminescence and broad excitation spectra [10,18]. CQDs may therefore be a promising alternative to the traditional toxic heavy metal-based semiconductor QDs in a wide range of applications.…”
