Scholarcy highlights

  • Biomaterials are a key element of medical devices
  • Because of potential toxicity issues for nanomaterials in general when used as free particles, the current strategy is to favour their use in nanocomposite materials, as load in a biocompatible matrix
  • We have focused especially on hydrogel matrices, which are currently intensively investigated for biomedical applications
  • It was shown that mechanical and electrical properties of hydrogels could be greatly improved by embedding carbon nanotubes and that those nanocomposites could be used for biosensing, tissue engineering and drug delivery without the risk of CNT release into cells
  • The 3D porous structure of hydrogel widens the possible range of applications, offering more versatility, as shown by the recent development of injectable tissue scaffolds or drug delivery patches
  • As described in this work, CNT confinement inside hydrogels is a good way to limit their scattering inside the organism, representing a promising way of taking advantages of those carbon nanoparticles for biomedical applications
