TL;DR: In this paper, the thermal stability of magnetite nanoparticles was investigated by thermogravimetric analysis (TG/DTG/DTA) in air and nitrogen atmosphere, and it was found that magnetic NPs coated by polymer blend were characterized by lower thermal stability than protected only by alone modified chitosan (m-CS) or m-CS.

TL;DR: In this paper, three different novel chitosan derivatives for medical or biotechnological applications have been successfully obtained by chemical modification of reactive amino and hydroxyl groups in chitosa chain, which led to incorporation of different amount (one to three) of long-distanced amino and imine groups into each repeating unit.

TL;DR: New magnetic nanoparticles based on Fe3O4 and coated with chemically modified chitosan with surface rich of free amino groups distanced from the polymer chain are prepared and applied for bioligands immobilization.

TL;DR: In this article, superparamagnetic nanoparticles were surface modified with a mixture of two polymers for lipase immobilization and the results demonstrate that application of the support prepared with the use of polymeric quaternized ammonium salt (CS−PQ (1:1)) allows to obtain high activity recovery (higher than 80%) in comparison with other tested nanoparticles.

TL;DR: The results showed that the selected nanoparticles are a promising semi-quantitative tool for the identification of high affinity compounds to AR and might be of special importance in the Identification of novel agonists or antiandrogens.
