Porous ZnS and ZnO nano-crystal films were fabricated via a three-step procedure. First, Zn(CH 3 COO) 2 /Silk Fibroin nanofiber mats were prepared by coaxial electrospinning. Second, Zn(CH 3 COO) 2 /Silk Fibroin mats were immersed in NaS solution to react with S 2À to obtain ZnS/Silk Fibroin nanofiber mats. Finally, ZnO porous films were prepared by calcination of ZnS/Silk Fibroin composite mat at 600°C in air atmosphere. When ZnS/Silk Fibroin mats were calcinated in nitrogen, ZnS/Carbon composite mats were obtained accordingly. The resulting porous films were fully characterized. The ZnO porous films were the aggregation of ZnO nano-crystal with hexagonal wurtzite structure. The seize of ZnO was estimated in the range of 10-20 nm. Both of the ZnS and ZnO nano-crystal films exhibited high photocatalytic activities for the photodegradation of Methylene blue and Rhodamine B. It was also found that ZnO porous films are better than ZnS/Carbon nanofiber mats. In addition, photocatalysis of a real wastewater sample from a printing and dyeing company was conducted. The ZnO porous films exhibited excellent performance to treat the real samples. Moreover, the porous ZnO nano-crystal photocatalyst could easily be recycled without notable loss of catalysis ability.

“…Biocompatible polymers used to modify MBs can be classified into the two categories: (i) natural macromolecules (such as glucan, chitosan, and amino acids); (ii) synthetic macromolecules (such as PEG, PVP, PS, PMMA, and PLA). At present, the research on organic polymer modified MBs mainly focuses on the two aspects: (i) the synthesis of polymer MBs with high content and uniform size; (ii) the development of polymer/MBs composite particles with a clear core‐shell structure . Notable efforts concerning these research directions are discussed in the following paragraphs.…”

As a result of their advantages for superparamagnetic properties, good biocompatibility, and high binding capacity, functionalized magnetic materials became widely popular over the past couple of decades, being applied on large scale in various processes of sample preparation for biomedicine. In this work, we perform an in‐depth review on the current progress in the field of magnetic bead separation, discussing in detail the physical basis of this process, various synthesis methods and surface modification strategies. We place special focus of attention as well on the latest applications of magnetic polymer microspheres in cell separation, protein purification, immobilized enzyme, nucleic acid separation, and extraction of bioactive compounds with low molecular weight. Existing problems are highlighted and possible trends of magnetic separation techniques for biomedicine in the future are proposed.

A solid-phase extraction adsorbent based on an aptamer-functionalized magnetic conjugated organic framework (COF) was developed for selective extraction of traces of hydroxylated polychlorinated biphenyls. This material has advantages such as superparamagnetism of the magnetic core, high surface area and porous structure of the COF, and high specific affinity of the aptamer. In combination with HPLC-MS, the aptamer-functionalized magnetic COF was used for the capture of hydroxy-2',3',4',5,5'-pentachlorobiphenyl in human serum. The method provided a linear range of 0.01-40 ng mL with a good correlation coefficient (R =0.9973). The limit of detection was as low as 2.1 pg mL . Furthermore, the material showed good reusability and could be applied in at least ten extraction cycles with recoveries greater than 90 %.
