Thermal actuation of hydrogels from PNIPAm, alginate, and carbon nanofibres

Synthesis and Magneto-Thermal Actuation of Iron Oxide Core–PNIPAM Shell Nanoparticles

Superparamagnetic nanoparticles have been proposed for many applications in biotechnology and medicine. In this paper, it is demonstrated how the excellent colloidal stability and magnetic properties of monodisperse and individually densely grafted iron oxide nanoparticles can be used to manipulate reversibly the solubility of nanoparticles with a poly(N-isopropylacrylamide)nitrodopamine shell....

New biocompatible thermo-reversible hydrogels from PNiPAM-decorated amyloid fibrils.

New biocompatible temperature-responsive hydrogels have been obtained by using unprecedented low concentration of amyloid fibril-PNiPAM hybrids. The viscoelasticity of the hydrogels can be finely controlled by tuning the PNiPAM layers without changing the structure or concentration of the amyloid fibrils.

Advanced alginate-based hydrogels

The search for suitable three-dimensional (3D) scaffolds analogous to the natural extracellular matrices is a central task in the field of tissue engineering (TE). These scaffolds should deliver cells to the desired site in the patient’s body supporting the formation of new tissue [1]. Various hydrogels have recently been used to mimic the extracellular matrix of several tissues; however the ad...

Surface Oxidation of Carbon Nanofibres

Carbon nanofibres of the fishbone and parallel type were surface-oxidised by several methods. The untreated and oxidised fibres were studied with infrared spectroscopy, thermogravimetric analysis and XPS. Oxidation in a mixture of concentrated nitric and sulfuric acid turned out to be the most effective method for creating oxygen-containing surface groups. This treatment results not only in the...
