Abstract
Skin and soft tissue infections caused by Pseudomonas aeruginosa are common acquired diseases in postpartum care. Many methods have been developed in recent years for detecting P. aeruginosa, but they are criticized for the drawbacks of labor-intensiveness, complicated operation and high cost. Here, a simple, sensitive and colorimetric assay for P. aeruginosa detection is described. The approach displays a green color for positive samples and colorless for target-free samples. The approach exhibits a wide detection range and a low limit of detection of 45 CFU/ml. Thus, the developed ligation-initiated multiple-signal amplification method may be used for on-site testing of pathogenic bacteria and assist in the early diagnosis of postpartum care skin infections.

Abstract
Even though it is very important, it is still rather difficult to detect minuscule levels of the bacterial pathogen in clinical practice, such as samples from dental implants. We construct here an efficient scaffold for label-free and sensitive Staphylococcus aureus (S. aureus) detection. The precise recognition of target bacteria by the detection scaffold leads to the self-assembly of Chain i and DNAzyme based cleavage of Chain iii. In detail, active DNAzyme conformation is formed based on the hybridization of Chain iii and Chain ii, and a nicking site is generated in Chain iii, making it possible to form a self-primer in Chain i. With the assistance of DNA polymerase, a single-strand DNA chain is added to the 3' terminal of Chain i, in which process the bacteria is released for the complex to bind with a next detection scaffold, forming a signal recycle. Following DNAzyme-based cleavage, the liberated sequences unroll MB and release G-rich sequences that can specifically bind with the fluorescent dye Thioflavin T (ThT), initiating ThT's fluorescence signal production. The approach demonstrates a wide detection range of 102 CFU/mL and 106 CFU/mL with a low limit of detection of 45 CFU/mL based on the developed detection scaffold, offering good prospects in the diagnosis of bacterial illnesses.

Abstract
Dopamine (DA) plays an essential role in dopaminergic neuronal behavior and disease. However, current detection methods for discriminating the secretion of DA are hampered by the limitations of the requirement for bulky instrumentation and non-intuitive signals. Herein, we have controllably and proportionately integrated molybdenum disulfide (MoS2) with titanium dioxide (TiO2) to prepare MoS2@TiO2 nanocomposites (MoS2@TiO2 NCs) via a facile synthesis method. MoS2@TiO2 NCs with a certain reactant mass ratio have shown a significant enhancement in peroxidase-like activity with superiority of the nanocomposite structure compared to single MoS2 or natural enzyme. The method for catalyzing the decomposition of H2O2 by MoS2@TiO2 NCs and competition for hydroxyl radicals (˙OH) between the chromogenic agent and DA enable a sensitive, specific, and colorimetric DA analysis with a low detection limit of 0.194 μM and a wide linear detection range (0.8 to 100 μM). Because of the favorable detection performance, we were encouraged to explore and finally realize the visual detection of cellular DA secretion that is stimulated in a High-K+ neurocyte environment. Collectively, this method will provide a promising strategy for basic research in neuroscience with its portable, sensitive, and naked-eye detectable performance.

Abstract
MXene is a rapidly emerging group of two-dimensional (2D) multifunctional nanomaterials, drawing huge attention from researchers of a broad scientific field. Reporting the synthesis of MXene was the following breakthrough in 2D materials following the discovery of graphene. MXene is considered the most recent developments of materials, including transition metal carbonitrides, nitrides, and carbides synthesized by etching or mechanical-based exfoliation of selective MAX phases. MXene has a plethora of prodigious properties such as unique interlayer spacing, high ion and electron transport, large surface area, excellent thermal and electrical conductivity, exceptional volumetric capacitance, thermal shock, and oxidation resistance, easily machinable and inherently hydrophilic, and biocompatibility. Owing to the abundance of tailorable surface function groups, these properties can be further enhanced by surface functionalization with covalent and non-covalent modifications via numerous surface functionalization methods. Therefore, MXene finds their way to a plethora of applications in numerous fields including catalysis, membrane separation, energy storage, sensing, and biomedicine. Here, the focus is on reviewing the structure, synthesis techniques, and functionalization methods of MXene. Furthermore, MXene-based detection platforms in different sensing applications are survived. Great attention is given to reviewing the applications of MXene in the detection of biomolecules, pathogenic bacteria and viruses, cancer biomarkers food contaminants and mycotoxins, and hazardous pollutants. Lastly, the future perspective of MXene-based biosensors as a next-generation diagnostics tool is discussed. Crucial visions are introduced for materials science and sensing communities to better route while investigating the potential of MXene for creating innovative detection mechanisms.

Abstract
Here we report a bacteria detection method based on a flow cytometric bead system and 16S rRNA-targeted oligonucleotide probes. Polymerase chain reaction (PCR) was first used to acquire bacterial DNA including bacteria-specific sequences. Half of the resulting target DNA was then captured by a capture probe immobilized on a magnetic microbead (MB) surface. The other half of the target DNA was hybridized with a fluorescence-labeled signal probe. In this manner, a sandwich DNA hybridization involving a MB-based capture probe, the target DNA, and a signal probe was realized. The MB carriers modified with reporter dye were analyzed one by one by flow cytometry through a capillary. Using PCR amplicons and this flow cytometric bead system, a detection limit of 180 cfu mL-1 was achieved, along with high selectivity that permitted the discrimination of different targets when challenged with control bacteria targets and multiplexing capabilities that enabled the simultaneous detection of two kinds of bacteria. Given these advantages, the developed method can be used for the highly sensitive and specific PCR amplicon analysis of DNA extracted from a fresh bacterial culture, as well as multiplex target analysis. Graphical abstract The flow cytometric bead system with 16S rRNA-targeted oligonucleotide probes for bacteria detection developed in this work. This system is highly specific and sensitive, with a detection limit of 180 cfu mL-1 bacteria.
