Pulling on super paramagnetic beads with micro cantilevers: single molecule mechanical assay application
(IOP Publishing, 2015)
This paper demonstrates that it is possible to trap and release a super paramagnetic micro bead by fixing three super paramagnetic micro beads in a triangular array at the sensitive end of a micro cantilever, and by simply ...
Isolation of adipose derived mesenchymal stem cells by using anti-CD105 VHH-magnetic beads
(Pontificia Universidad Catolica de Valparaiso, 2023)
Background: Human adipose tissue-derived stem cells (ASCs) are widely used in regenerative medicine and tissue engineering. Magnetic-activated cell sorting (MACS) with monoclonal antibodies (mAbs) that bind surface markers ...
Different approaches for the detection of thrombin by an electrochemical aptamer-based assay coupled to magnetic beads
(Elsevier Advanced Technology, 2008-06)
Different assay formats based on the coupling of magnetic beads with electrochemical transduction were compared here for the detection of thrombin by using a thrombin specific aptamer. By using the thrombin-binding aptamer, ...
Synthesis, characterization and applications of maghemite beads functionalized with rabbit antibodies
(2018-06-28)
Magnetic nanoparticles (NPs) have attracted great attention owing to their applications in the biomedical field. In the present work, maghemite (γFe2O3) NPs of 6.5 nm were prepared using a sonochemical method and used to ...
Dipolar interactions among magnetic dipoles of iron oxide particles dispersed in mili-size hydrogel beads
(Elsevier Science, 2020-11-01)
The recently published Mean Field Interacting Superparamagnet Model (MFISP model), whichintroduces the effective demagnetizing factor , is tested in specimens having a random-likespatial distribution of magnetic nanoparticles, ...
Immobilization of marine toxins on carboxylic acid modified surfaces

Tillandsia Aeranthos flower-like magnetic nanostructures confined into polyvinyl alcohol beads
(John Wiley & Sons Inc, 2020-11)
Magnetic beads composed by polyvinyl alcohol and iron oxides were developed and fully characterized. The materials were not only cross-linked by a physical treatment but also the magnetic nanoparticles (MNPs) are acting ...
A disposable voltammetric immunosensor based on magnetic beads for early diagnosis of soybean rust
(ElsevierLausanne, 2012)
Electrochemical sensing using magnetic molecularly imprinted polymer particles previously captured by a magneto-sensor
(2018-05-01)
The determination of 1-chloro-2,4-dinitrobenzene (CDNB) was used as a proof-of-concept to a simple analytical practical configuration applying magnetic molecularly imprinted particles (mag-MIPs). Mag-MIPs were captured ...
Biotransformation of cladribine by a magnetic immobilizated biocatalyst of Lactobacillus animalis
(Springer, 2020-07)
A stable biocatalyst with magnetic properties based on immobilized Lactobacillus animalis ATCC 35,046 to obtain 2-chloroadenine-2′-deoxyriboside, known as cladribine, is reported for the first time. This nucleoside analogue ...
