Engineering Homochiral MOFs in TiO2 Nanotubes as Enantioselective Photoelectrochemical Electrode for Chiral Recognition

“…Metal–organic frameworks (MOFs), a new three-dimensional (3D) extension material with a microporous structure composed of metal ions and organic ligands, have attracted much attention in recent years. − The advantageous properties of MOFs, such as a large specific area, plenty of functional groups, well-defined pore size, and tunable chemical compositions, make them attractive for a wide range of applications such as gas storage, catalysis, drug delivery, chemical sensing, and molecule separation. , Recently, some MOFs such as MOF-5 and ZnO@ZIF-8 nanorods exhibited good performances in photoelectric chemistry. With the development of monochiral MOFs, the application of monochiral MOFs and their functionalized hybrids for the separation of enantiomers and monitoring the related recognition mechanism has become an important research direction of chiral recognition.…”

Laccase-Conjugated Nanostructured ZnFe2O4/rGO-Modified Electrode-Based Interfaces for Electrochemical Impedance Monitoring of Adrenaline: A Promising Biosensor for Management of Neurodegenerative Disorders

“…Among these applications, electrochemical sensing is one of the most promising and challenging applications, as it requires nanomaterial-based biosensors that have outstanding sensitivity, selectivity, stability, and repeatability. , ZF nanoparticles exhibit robust electrocatalytic activity toward several analytes, namely, cholesterol, nitrite, hydrogen peroxide, glucose, and dopamine. , However, there are significant challenges that limit ZF nanoparticles from being fully utilized for electrochemical sensing, such as low conductivity, poor dispersion, and agglomeration tendency . To overcome these drawbacks, several strategies have been proposed to modify ZF nanomaterials with other functional materials, such as metal nanoparticles, polymers, carbon-based materials, carbon nanotubes, and graphene. , Among them, rGO is a particularly attractive candidate, as it possesses high conductivity, large surface area, abundant active sites, and excellent mechanical flexibility . The combination of ZF and rGO can form a synergic nanohybrid that can enhance the electrochemical sensing performance.…”
