A new low cost magnetic material: magnetic polyvinylbutyral microbeads

Characterization of chitosan magnetic nanoparticles for in situ delivery of tissue plasminogen activator

“…Chitosan-MNP coated with more chitosan apparently will therefore lead to a lower saturation magnetization (Nara, Torii, & Tasumi, 1996). Even though the saturation magnetization value of Fe 3 O 4 MNP decreases after chitosan coating, it is higher than that when Fe 3 O 4 MNP was modified with oleic 2θ (degree) acid or encapsulated within a polymer matrix (Tanyolac & Ozdural, 2000). Thermogravimetric and differential thermal analysis results are shown in Fig.…”

Magnetic nano- and microparticles for metal removal and environmental applications: a review

“…Typical polymers used are polyacrylamide, polymethylmethacrylate, polyvinylalcohol, polyethylenglycol [27]. Polyacrylamide based polymers seems to give the better results for extractants adsorption [23].…”

Synthesis and characterization of magnetic β-cyclodextrin–chitosan nanoparticles as nano-adsorbents for removal of methyl blue

“…The ␤-cyclodextrin-chitosan (CDC) modified Fe 3 O 4 nanoparticles (CDCM) can make separation process simple and fast, because it can be easily collected by an external magnetic field without additional centrifugation or filtration [12][13][14][15]. Compared to the traditional micron-sized supports used in separation process, nano-sized adsorbents possess quite good performance due to high specific surface area and the absence of internal diffusion resistance, which improve adsorption capacity.…”
