“…In view of the complementary properties of NiMn LDH with poor electrical conductivity and N-CNTs with good electron transfer rate, the NiMn LDH/N-CNT nanocomposite was successfully prepared through Ni–N/Mn–N bonds and electrostatic force between the negatively charged N-CNTs and positively charged NiMn LDH (Figure. d). , Second, the CV technique was employed to verify the synergistic effect of NiMn LDH and N-CNTs, and the results are displayed in Figure e. Compared to the bare GCE (curve i), NiMn LDH (curve ii) and N-CNTs (curve iii) showed two trends due to different conductivity.…”

Early secretory antigenic target-6 (ESAT-6) is regarded as the most immunogenic protein produced by Mycobacterium tuberculosis, whose detection is of great clinical significance for tuberculosis diagnosis. However, the detection of the ESAT-6 antigen has been hampered by the expensive cost and complex experimental procedures, resulting in low sensitivity. Herein, we developed a titanium carbide (Ti 3 C 2 T x )-based aptasensor for ESAT-6 detection utilizing a triple-signal amplification strategy. First, acetylene black (AB) was immobilized on Ti 3 C 2 T x through a cross-linking reaction to form the Ti 3 C 2 T x -AB-PAn nanocomposite. Meanwhile, AB served as a conductive bridge, and Ti 3 C 2 T x can synergistically promote the electron transfer of PAn. Ti 3 C 2 T x -AB-PAn exhibited outstanding conductivity, high electrochemical signals, and abundant sites for the loading of ESAT-6 binding aptamer II (EBA II) to form a novel signal tag. Second, N-CNTs were adsorbed on NiMn layered double hydride (NiMn LDH) nanoflowers to obtain NiMn LDH/N-CNTs, exhibiting excellent conductivity and preeminent stability to be used as electrode modification materials. Third, the biotinylated EBA (EBA I) was immobilized onto a streptavidin-coated sensing interface, forming an amplification platform for further signal enhancement. More importantly, as a result of the synergistic effect of the triple-signal amplification platform, the aptasensor exhibited a wide detection linear range from 10 fg mL −1 to 100 ng mL −1 and a detection limit of 4.07 fg mL −1 for ESAT-6. We envision that our aptasensor provides a way for the detection of ESAT-6 to assist in the diagnosis of tuberculosis.

Among the recent developments in metal-organic frameworks (MOFs), porous layered coordination polymers (CPs) have garnered attention due to their modular nature and tunable structures. These factors enable a number of properties and applications, including gas and guest sorption, storage and separation of gases and small molecules, catalysis, luminescence, sensing, magnetism, and energy storage and conversion. Among MOFs, two-dimensional (2D) compounds are also known as 2D CPs or 2D MOFs. Since the discovery of graphene in 2004, 2D materials have also been widely studied. Several 2D MOFs are suitable for exfoliation as ultrathin nanosheets similar to graphene and other 2D materials, making these layered structures useful and unique for various technological applications. Furthermore, these layered structures have fascinating topological networks and entanglements. This review provides an overview of different aspects of 2D MOF layered architectures such as topology, interpenetration, structural transformations, properties, and applications.
