“…Regeneration of the purification media has been approached through the addition of acids, bases, or solvents to remove the absorbed pollutant, addition of more strongly binding species to cause exchange, and through the addition of an oxidant to remove the polluted coating and allow recoating of the media . Media used have included magnetic nanoparticles, taking advantage of the magnetic properties for solid phase extraction of the binding agent.…”

“…Other ways to increase the efficiency of pollutant removal of polydopamine coated media is to modify the coating. This includes modification with other absorbents (magnesium–aluminum layered double hydroxide nanoflakes, mesoporous silica nanoparticles, chitosan, polyethyleneimine, polyaspartate, chloro(dimethyl)octadecylsilane, a zirconium‐based metal–organic framework, and amidoxime polymer brushes) to increase removal of specific pollutants. The use of stabilizing polymers (polyethyleneimine and β‐cyclodextrin) was to make absorption from basic solution and regeneration with simple acid and base washes more effective .…”

Almost ten years ago, Lee et al. [13] formulated a universal adhesive coating based on observation of the strong attachment by mussels through their byssal threads to virtually all types of inorganic and organic surfaces. The amino acid compositions of the mussel foot proteins that generate the attachment are rich in catechol and amine groups. [13][14][15] These groups associate under marine conditions, forming strong covalent and noncovalent interactions with substrates. [13] This led to the idea that both catechol and amine groups were crucial in forming robust, wide spectrum adhesive nanolayers [16,17] and consequently dopamine was conceived as a powerful building block for spontaneous deposition of thin polymer films. The dopamine monomer is deposited onto unadulterated surfaces through self-assembly and oxidative cross-linking from mild pH aqueous solution in a rapid reaction. This results in a durable, nanoscale, conformal, and hydrophilic coating that can be readily modified to introduce specific surface chemistries for a particular application. [18][19][20][21][22] These bioinspired, polydopamine materials are chemically and structurally indistinguishable from eumelanins found in the human body, [23,24] providing excellent biocompatibility. Additionally, polydopamine has broad electromagnetic absorption and excellent photothermal energy conversion [25] as well as having ionic-electronic hybrid conductivity. [26] Along with the excellent coating performance, these properties provide a vast array of potential applications for polydopamine materials.In this article, we explain what is known about polydopamine and related catecholamine coatings; their formation, the adhesion mechanism, and their physicochemical properties and we also review the applications of these materials (Figure 1). Since 2011, there have been a number of reviews on this subject matter, including general reviews on the physicochemical properties of polydopamine coatings [11,20,[27][28][29] and their applications. [20,27,30] There are also a number of more specific reviews on the chemical synthesis and modulation of polycatecholamine coatings, [31] the biomedical applications of these coatings, [8,[32][33][34] their electronic properties, [26,35] the use of polydopamine to make films at fluid interfaces, [36] in hierarchically constructed particles, [33] and capsules, [30] exploitation of polycatecholamine coatings in membrane filtration, [37] polydopamine-derived carbon materials, [38] and the use of coordination chemistry in catechol-based materials. [39] Nonetheless, this area of research is growing so rapidly [25,27] that many recent Polydopamine and related polycatecholamines can be easily deposited onto almost any surface from mild, aqueous solution. This results in durable, nanoscale coatings that exhibit high biocompatibility and have useful chemical and electronic properties. Additionally, these materials can be readily chemically and physically modified, and consequently, they are used extensively for surface modification. This ...

“…Magnetic MOFs, a special type of MOFs, have a wide range of applications such as adsorbents and separation 5. Many metals such as zirconium-based magnetic MOFs6 and Fe 3 O 4 @SiO 2 @UiO-66 core–shell magnetic microspheres can be used as sorbents in solid-phase extraction 7. Another study shows that magnetic MOFs have been used as magnetic solid-phase extraction adsorbents in preconcentration of pyrazole/pyrrole pesticides in environmental water samples8 and also in chemical sensing9 and drug delivery 10.…”

Metal–organic frameworks (MOFs) are structures made up of inorganic nodes, which can be either single ions or clusters of ions and organic linkers. This study reports on a novel processing route for producing β-estradiol encapsulated in Zn-MOF nanocomposites by microwave-assisted coprecipitation as a facile and fast method. Zn-MOF nanocomposites were synthesized with the aid of Zn(OAc)2⋅2H2O and 2,6-pyridine dicarboxylic acid ammonium as an organic ligand. Furthermore, we studied encapsulated β-estradiol which is one of the most important classes of estrogenic compounds that are used in the treatment of prostate cancer and breast cancer. The effects of β-estradiol concentration and microwave irradiation on the morphology, particle size, distribution, and in vitro photoluminescence spectroscopy experiments of β-estradiol entrapped in Zn-MOF nanocomposites were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, ultraviolet–visible spectroscopy, Fourier transform infrared spectroscopy, and Brunauer–Emmett–Teller spectroscopy. These nanostructures can be a good option for thawing hydrophilic and hydrophobic drugs over time. Zn-MOF nanocomposites with high porosity, total pore volume (0.04665 cm3g−1), and nanostructures have provided the platform to load β-estradiol such as low soluble drugs. Maximum of drug release was about 82% at pH 8.9 after 8 h.

“…Magnetic solid-phase extraction (MSPE) is a new mode of SPE based on the magnetization of adsorbents which can be easily separated and purified during the synthesis and application process by introducing an extra magnetic field [22][23][24][25][26][27][28][29]. Magnetic core-shell MOF hybrids are rarely used in MSPE because controlling the heterogeneous growth of MOF crystals on the surface of magnetic nanoparticles remains a great challenge.…”

Core-shell metal-organic framework materials have attracted considerable attention mainly due to their enhanced or new physicochemical properties compared with their single-component counterparts. In this work, a core-shell heterostructure of CoFe2 O4 -Zeolitic Imidazolate Framework-8 (ZIF-8@CoFe2 O4 ) is successfully fabricated and used as an solid-phase extraction adsorbent to efficiently extract Congo Red and Basic Red 2 dyes from contaminated aqueous solution. Vibrating sample magnetometry indicates that the saturated magnetization of ZIF-8@CoFe2 O4 is 3.3 emu/g, which is large enough for magnetic separation. The obtained hybrid magnetic metal-organic framework based material ZIF-8@CoFe2 O4 can remove the investigated dyes very fast within 1 min of the contact time. The adsorbent ZIF-8@CoFe2 O4 also shows a good reusability. After regeneration, the adsorbent can still exhibit high removal efficiency (∼97%) toward Congo Red for five cycles of desorption-adsorption. This work reveals the great potential of core-shell ZIF-8@CoFe2 O4 sorbents for the fast separation and preconcentration of organic pollutants in aqueous solution before high-performance liquid chromatography analysis.
