Layered double hydroxides (LDHs) have attracted considerable attention as promising materials for electrochemical and optical sensors owing to their excellent catalytic properties, facile synthesis strategies, highly tunable morphology, and versatile hosting ability. LDH-based electrochemical sensors are affordable alternatives to traditional precious-metal-based sensors, as LDHs can be synthesized from abundant inorganic precursors. LDH-modified probes can directly catalyze or host catalytic compounds that facilitate analyte redox reactions, detected as changes in the probe’s current, voltage, or resistance. The porous and lamellar structure of LDHs allows rapid analyte diffusion and abundant active sites for enhanced sensor sensitivity. LDHs can be composed of conductive materials such as reduced graphene oxide (rGO) or metal nanoparticles for improved catalytic activity and analyte selectivity. As optical sensors, LDHs provide a spacious, stable structure for synergistic guest–host interactions. LDHs can immobilize fluorophores, chemiluminescence reactants, and other spectroscopically active materials to reduce the aggregation and dissolution of the embedded sensor molecules, yielding enhanced optical responses and increased probe reusability. This review discusses standard LDH synthesis methods and overviews the different electrochemical and optical analysis techniques. Furthermore, the designs and modifications of exemplary LDHs and LDH composite materials are analyzed, focusing on the analytical performance of LDH-based sensors for key biomarkers and pollutants, including glucose, dopamine (DA), H2O2, metal ions, nitrogen-based toxins, and other organic compounds.

“…1b, the absorption peak at 3107 cm −1 is attributed to the stretching vibration of the unsaturated C–H on the benzene ring; 37 the strong peaks at 1609 and 1538 cm −1 correspond to the vibration of the CC skeleton in the benzene ring; 38 the peaks at 3003 and 2908 cm −1 correspond to the antisymmetric and symmetric stretching modes of the CH 3 group, 39 respectively; and the absorption peak at 1282 cm −1 is attributed to the stretching vibration of the O–S bond. 40–42 In addition, EDS data show that Bi (or Sb), Br, and S are uniformly distributed in the crystal (Fig. 2b and c) and that the atomic ratios are Bi : Br : S = 1 : 5.74 : 1.14 and Sb : Br : S = 1 : 5.44 : 1.23 (Fig.…”

Layered rare-earth hydroxides (LREH, RE = Y, Eu) were employed as a host material to construct hybrid systems together with an Nsubstituted naphthalene diimide sulfonate (NDI-SO 3 ). The initial emission spectrum of NDI-SO 3 in the presence of LYH displayed a green emission (513 nm) arising from the NDI-SO 3 excimer-type state. After 30 min, the excimer-type state disappeared and a J-type aggregate was formed. Doping LYH with Ce 3+ ions led to the formation of a UV-emitting material (LYH:Ce). The incorporation of NDI-SO 3 in a LYH:Ce colloidal dispersion generated the same aggregate species of NDI-SO 3 as LYH, and by varying the concentration of Ce 3+ in LYH:Ce, suppression of the formation of emitting NDI-SO 3 species was observed. Quenching followed by recovery of the fluorescence of Ce was observed upon the addition of NDI-SO 3 . NDI-SO 3 in the presence of LEuH displayed only the emission of the monomeric form of the dye, and no aggregation was detected. NDI-SO 3 /LEuH were used as a donor/acceptor pair system, where quenching of NDI-SO 3 and the concomitant increase of Eu 3+ emission indicated efficient energy transfer between NDI and LREH. The intriguing aggregation and energy transfer between a photoactive inorganic host and organic guest offers a promising approach to achieve materials with tunable luminescence. This study encourages further studies on the preparation of new organic−inorganic hybrids, particularly toward an understanding of host−guest interactions at the interface of LREH particles. Furthermore, understanding the role of NDI aggregation on energy transfer processes at nanomaterial interfaces will advance future applications in optoelectronics, energy, and sensing.
