Int J Mol Sci 2023; 24:ijms24076713. [PMID: 37047685 PMCID: PMC10095318 DOI: 10.3390/ijms24076713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 03/31/2023] [Accepted: 04/01/2023] [Indexed: 04/14/2023] Open
Abstract
To vectorize drug delivery from electrospun-produced scaffolds, we introduce a thin outer drug retention layer produced by electrospinning from activated carbon nanoparticles (ACNs)-enriched polycaprolacton (PCL) suspension. Homogeneous or coaxial fibers filled with ACNs were produced by electrospinning from different PCL-based suspensions. Stable ACN suspensions were selected by sorting through solvents, stabilizers and auxiliary components. The ACN-enriched scaffolds produced were characterized for fiber diameter, porosity, pore size and mechanical properties. The scaffold structure was analyzed by scanning electron microscopy and X-ray photoelectron spectroscopy. It was found that ACNs were mainly coated with a polymer layer for both homogeneous and coaxial fibers. Drug binding and release from the scaffolds were tested using tritium-labeled sirolimus. We showed that the kinetics of sirolimus binding/release by ACN-enriched scaffolds was determined by the fiber composition and differed from that obtained with a free ACN. ACN-enriched scaffolds with coaxial and homogeneous fibers had a biocompatibility close to scaffold-free AC, as was shown by the cultivation of human gingival fibroblasts and umbilical vein cells on scaffolds. The data obtained demonstrated that ACN-enriched scaffolds had good physico-chemical properties and biocompatibility and, thus, could be used as a retaining layer for vectored drug delivery.

Abstract
In this study, porous electrospinning polyacrylonitrile nanofiber (PPAN) surface functionalization with amine groups is studied for methyl orange (MO) dye removal from aqueous solution. A series of adsorption experiments were carried out to investigate the influence of initial solution pH value, contact time, initial solution concentration, and adsorption temperature on the adsorption performance. The experimental results showed that the removal of MO on these PPAN-PEI and PPAN-TEPA nanofibrous mats was a pH-dependent process with the maximum adsorption capacity at the initial solution pH of 3, and that the PPAN-PEI and PPAN-TEPA nanofibrous mats could be regenerated successfully after 4 recycling processes. The adsorption equilibrium data were all fitted well to the Langmuir isotherm equation, with maximum adsorption capacity of 1414.52 mg g−1 and 1221.09 mg g−1 for PPAN-PEI and PPAN-TEPA, respectively. The kinetic study indicated that the adsorption of MO could be well fitted by the pseudo-second-order equation and Weber–Morris model. Thermodynamic parameters such as free energy, enthalpy, and entropy of adsorption of the MO were also evaluated, and the results showed that the adsorption was a spontaneous exothermic adsorption process. Amino functionalized porous polyacrylonitrile electrospun nanofibers were fabricated, which have good adsorption performance for MO in an acidic environment.![]()

JOURNAL OF HAZARDOUS MATERIALS 2022; 426:128074. [PMID: 34954431 DOI: 10.1016/j.jhazmat.2021.128074] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 11/23/2021] [Accepted: 12/09/2021] [Indexed: 06/14/2023]
Abstract
The coexistence of pathogenic microorganisms and refractory organic chemicals in water nurtures certain biological and chemical risks to human beings and the water environment as a whole. For an environmentally friendly utilization of water cleaning and recycling technologies, a bifunctional cationic cyclodextrin material (GD-DTAC) with adsorption and bactericidal function was designed. By a simple crosslinking method, GD-DTAC was prepared with graphene supported citric acid-β-cyclodextrin polymer (GD) and dimethyldodecyl[3-(trimethoxysilyl)propyl]ammonium chloride (DTAC). Following the introduction of rich quaternary ammonium groups by DTAC, GD-DTAC realized a double regulation of surface positive charge and wettability. The maximum adsorption capacities of Roxarsone (ROX), Methyl Orange (MO) and Bisphenol A (BPA) were 153.59 mg/g, 445.60 mg/g and 237.90 mg/g, respectively. Antibacterial activity tests showed the efficiency of DTAC not only for enhanced adhesion resistance, but it also realized the sterilization function. This work displays the potential of the prepared bifunctional materials for the removal of pollutants from wastewater as well as the suppression of micro-pollutants. The successful preparation of GD-DTAC provided a basis for the bifunctional material, which showed a great potential in adsorption and antibiosis.

Abstract
The unique functions of nanofibers (NFs) are based on their nanoscale cross-section, high specific surface area, and high molecular orientation, and/or their confined polymer chains inside the fibers. The introduction of ion-exchange (IEX) groups on the surface and/or inside the NFs provides de novo ion-exchangers. In particular, the combination of large surface areas and ionizable groups in the IEX-NFs improves their performance through indices such as extremely rapid ion-exchange kinetics and high ion-exchange capacities. In reality, the membranes based on ion-exchange NFs exhibit superior properties such as high catalytic efficiency, high ion-exchange and adsorption capacities, and high ionic conductivities. The present review highlights the fundamental aspects of IEX-NFs (i.e., their unique size-dependent properties), scalable production methods, and the recent advancements in their applications in catalysis, separation/adsorption processes, and fuel cells, as well as the future perspectives and endeavors of NF-based IEMs.
