“…The increased amount of enzyme could improve the efficiency of enzyme fixation; however, it seemed that excessive enzyme might lead to aggregation, and reduce the efficiency of enzyme fixation products. The result was similar to the report of Wanich Suksatan et al [ 49 ]. The optimum immobilization temperature of enzyme was 25 °C, which is commonly described as room temperature.…”

“…The immobilized materials showed a decrease in the pores between TiO 2 nanoparticles and an increase in agglomeration ( Figure 5 c,d), indicating the successful immobilization of dextranase on TiO 2 nanoparticles. Wanich Suksatan et al had similar results in the study of dextro-anhydrase immobilization in novel Ni/Zn-based nanostructures [ 49 ].…”

Dextranase is widely used in sugar production, drug synthesis, material preparation, and biotechnology, among other fields. The immobilization of dextranase using nanomaterials in order to make it reusable, is a hot research topic. In this study, the immobilization of purified dextranase was performed using different nanomaterials. The best results were obtained when dextranase was immobilized on titanium dioxide (TiO2), and a particle size of 30 nm was achieved. The optimum immobilization conditions were pH 7.0, temperature 25 °C, time 1 h, and immobilization agent TiO2. The immobilized materials were characterized using Fourier-transform infrared spectroscopy, X-ray diffractometry, and field emission gun scanning electron microscopy. The optimum temperature and pH of the immobilized dextranase were 30 °C and 7.5, respectively. The activity of the immobilized dextranase was >50% even after 7 times of reuse, and 58% of the enzyme was active even after 7 days of storage at 25 °C, indicating the reproducibility of the immobilized enzyme. The adsorption of dextranase by TiO2 nanoparticles exhibited secondary reaction kinetics. Compared with free dextranase, the hydrolysates of the immobilized dextranase were significantly different, and consisted mainly of isomaltotriose and isomaltotetraose. The highly polymerized isomaltotetraose levels could reach >78.69% of the product after 30 min of enzymatic digestion.

“…Comparing the effects of Cu/DPA-MOF and Cu/DPA-MOF/OP/CS hydrogel shows that the Cu/DPA-MOF/OP/CS hydrogel was relatively more effective than Cu/DPA-MOF. The reason can be attributed to the specific surface area, and as mentioned, a higher specific surface area causes more effectiveness and efficiency in nanoparticles ( Asiri et al, 2022 ; Suksatan et al, 2022 ; Zeraati et al, 2022 ).…”

Today, with the indiscriminate use of antibiotics, we face the resistance of some bacterial strains against some antibiotics. Therefore, it is essential to report and synthesize new compounds with antimicrobial properties. A novel copper/dipicolinic acid–metal–organic framework cross-linked oxidized pectin and chitosan (Cu/DPA-MOF/OP/CS) hydrogel polymer was synthesized under environmental conditions with the controllable process, which uses biodegradable polymer compounds such as pectin and chitosan in its structure. The efficient physicochemical features of the synthesized Cu/DPA-MOF/OP/CS hydrogel using SEM, FT-IR, TGA, BET, XRD, and EDS/mapping were identified and confirmed. The newly synthesized Cu/DPA-MOF/OP/CS hydrogel showed activity against Gram-positive and Gram-negative bacterial strains and fungal species, and significant antibacterial and antifungal properties were observed. In antibacterial activity, the MIC against Gram-positive species was in the range of 16–128 mg/mL, the MIC against Gram-negative species was in the range of 64–256 mg/mL, and the MIC against fungal species was in the range of 128–512 mg/mL. In antimicrobial evaluations, in addition to the MIC test, the MBC test, the MFC test, and the IZD test were performed, and the results were reported. The results were compared with commercial antibiotics in the market. Development of novel nanostructures based on hydrogel polymers with distinctive functionality can affect the performance of these nanostructures in different areas.

“…The photocatalytic degradation tests further confirmed the excellent performance of electron-hole pair separation in the visible band, and the degradation efficiency of 10 ppm of acetaminophen reached 94.6% in 210 min. Suksatan and colleagues synthesized nanometer nickel-zinc bimetallic MOFs (NiZn-MOFs Figure S1b) with uniform morphology with the ultrasonic method [48]. Fourier transform infrared spectroscopy, specific surface area, and thermogravimetric analysis showed that, compared with monometallic materials (Ni-MOF and Zn-MOF), the samples of NiZn-MOFs had a larger Brunauer-Emmet-Teller (BET) specific surface area and porosity and higher thermal stability.…”

The binary metal organic framework (MOF) is composed of two heterometallic ions bonded to an organic ligand. Compared with monometallic MOFs, bimetallic MOFs have greatly improved in terms of structure, porosity, active site, adsorption, selectivity, and stability, which has attracted wide attention. At present, many effective strategies have been designed for the synthesis of bimetallic MOF-based nanomaterials with specific morphology, structure, and function. The results show that bimetallic MOF-based nanocomposites could achieve multiple synergistic effects, which will greatly improve their research in the fields of adsorption, catalysis, energy storage, sensing, and so on. In this review, the main preparation methods of bimetallic MOFs-based materials are summarized, with emphasis on their applications in adsorption, catalysis, and detection of target pollutants in water environments, and perspectives on the future development of bimetallic MOFs-based nanomaterials in the field of water are presented.
