Significant Attention

Nanomaterials, such as magnetic nanoparticles have attracted significant attention of medical area due to their capacity to improve the performance of immunoassays. Therefore the aim of this work was to study the bovine serum albumin (BSA) conjugation in superparamagnetic (MNPs)/poly(methyl methacrylate) (PMMA) nanoparticles with further characterization and application in enzyme-linked immunosorbent (ELISA) assay. The successful conjugation of BSA in MNPs- PMMA nanoparticles was confirmed by several techniques, including light scattering, zeta potential, transmission electron microscopy (TEM) and Lowry protein quantification assay. The superparamagnetic properties were confirmed by vibrating sample magnetometer. BSA conjugated MNPs-PMMA nanoparticles presented higher interactions with antibody than free BSA. The BSA + MNPs-PMMA nanoparticles (magnetic ELISA assay) reduced the time and increased the sensibility of traditional ELISA assay, reinforcing the idea that the use these nanomaterials are an excellent alternative for the immunoassays field.

In this study, poplar and Masson pine trees were used as raw materials to examine the structural characteristics of lignin that had been isolated with a phase separation system. Following phase separation, the structure of lignocresol (LC) was characterized with Fourier transform infrared (FTIR) spectroscopy, high-performance gel permeation chromatography (GPC), proton nuclear magnetic resonance (1H-NMR) spectroscopy, and two-dimensional heteronuclear single quantum coherence nuclear magnetic resonance (2D HSQC NMR) spectroscopy. Phase separation made it possible to analyze the proportions and the differences between various structural units in the isolated lignin, as well as the types of linkages between them. In-situ and real-time monitoring of the adsorption and desorption properties of the LC membranes were conducted with a bovine serum albumin (BSA) assay and a quartz crystal microbalance (QCM-D). Our findings revealed that the LC membrane of Masson pine adsorbed more BSA than that of poplar, indicating Masson pine LC molecules were more hydrophobic due to a higher proportion of guaiacyl (G)-type lignin units.

Pure Water Flux

This study investigates the effects of different grafting time on the polysulfone grafted methyl methacrylate (PSf-g-MMA) membrane performance. PSf-g-MMA was successfully prepared via UV radiation method. Methyl methacrylate (MMA) and benzophenon (BP) were used as a monomer and initiator respectively. Membrane performances were measured based on permeation and rejection of bovine serum albumin (BSA). Degree of grafting was found to increase as grafting time increases and the optimum time was found at 100 minutes. The results revealed that the pure water flux and rejection were significantly improved with the addition of grafting time. The present of MMA also were found to improve fouling properties of the membrane.
