In this work, an ultrasensitive photoelectrochemical (PEC) assay was established for sensitive DNA detection based on a novel SnS2/Co3O4 sensitized structure as a photoactive matrix and benzo-4-chlorohexadienone (4-CD) precipitate as a signal quencher. Noticeably, the photoelectric conversion efficiency of the SnS2/Co3O4 sensitized structure was dramatically enhanced due to the effective sensitization of Co3O4 toward SnS2, thus attaining an intense photocurrent response, which was sixfold higher than that of pristine SnS2. Additionally, with the assistance of Nt.BstNBI enzyme-assisted target cycling process, a limited amount of target DNA (a fragment of p53 gene) could be converted into extensive output DNA, which could hybridize with capture DNA to yield abundant DNA duplex for loading mimetic enzyme manganese porphyrin (MnPP). Subsequently, 4-chloro-1-naphthol (4-CN) could be catalyzed to form 4-CD precipitate by MnPP on the modified electrode surface with the existence of H2O2. Then, the 4-CD precipitate severely hampered electron transfer, causing a prominently diminished photocurrent response for DNA determination. The elaborated PEC assay not only extended the application of SnS2 in the PEC biosensing field but also manifested a wide linear range of 100 aM to 1 nM with a low detection limit of 30 aM, exhibiting enormous potential for the detection of various biomarkers or other targets in bioanalysis and disease diagnosis fields.

“…How a quantized field behave in such background is therefore an important question. Analysis of quantum fields in a higher dimensional spacetime with a Kaluza-Klein-like extra dimension has been reported in [7][8][9][10][11][12]. Gravitational particle production in braneworld cosmology and its implications have been studied in [13].…”

Energy momentum tensor of a conformally coupled quantum scalar field in five dimensional warped cosmological spacetimes is studied. We look at situations where the four dimensional part represents a cosmological thick brane and the scale of the extra dimension is time dependent.Renormalization of the components of the energy momentum tensor is achieved using adiabatic regularization method. The resulting energy and pressure densities explicitly show the effects of warping and the dynamic extra dimension on the created matter. We discussed how the created matter may accumulate to form thick branes along the extra dimension.

In recent years, sulfur-containing nanomaterials and their derivatives/composites have attracted much attention because of their important role in the field of biosensor, biolabeling, drug delivery and diagnostic imaging technology, which inspires us to compile this review. To focus on the relationships between advanced biomaterials and biosensors, this review describes the applications of various types of sulfur-containing nanomaterials in biosensors. We bring two types of sulfur-containing nanomaterials including metallic sulfide nanomaterials and sulfur-containing quantum dots, to discuss and summarize the possibility and application as biosensors based on the sulfur-containing nanomaterials. Finally, future perspective and challenges of biosensors based on sulfur-containing nanomaterials are briefly rendered.
