Smart water-based ferrofluid with stable state transition property: Preparation and its application in anionic dye removal

Ferrofluids and bio-ferrofluids: looking back and stepping forward

“…[742][743][744][745][746][747][748] Ferrofluids are used, by exploiting highly sensitive detection and imaging techniques based on nonlinear properties of nanomagnets or various liquid-phase adsorption/magnetic separation processes, to extract toxic and harmful analytes from different matrices. 123,124,[749][750][751][752][753] A ferrofluid-based biosensor for histamine detection in red wines is a combination of magnetic competitive lateral flow immunoassay strips and an inductive sensor using recombinant protein functionalized 10 nm mean size superparamagnetic iron-oxide NPs for the magnetic quantification of the toxic component. 754 The ferrofluid aided inductive biosensor was validated against ultrahigh-performance liquid chromatography analyses and proved to be successful as a histamine point-of-use analytical technique.…”

Facile synthesis of high-efficiency magnetic graphitic carbon nitride adsorbents for the selective removal of hazardous anionic dyes in wastewater

“…As far as the current research is concerned, most of the composites are prepared in the form of binary composites such as Fe 3 O 4 /g-C 3 N 4 , 40 PEI/g-C 3 N 4 , 41 and PEI/Fe 3 O 4 . 42 Herein, we report for the first time a novel ternary composite material PEI-Fe 3 O 4 /g-C 3 N 4 with strong adsorption and separation ability for selective removal of anionic dyes in wastewater. Fe 3 O 4 magnetic nanoparticles and PEI were introduced into g-C 3 N 4 by co-precipitation and physical impregnation, respectively.…”

Boundary Layer Flow of Williamson Hybrid Ferrofluid over A Permeable Stretching Sheet with Thermal Radiation Effects

“…Saeed et al, [10] claimed velocity profile gradient decrease as ferrofluid and viscosity parameter increase. Ferrofluid is also used to create new smart fluid and solar application like [11][12][13][14].…”
