Dear Colleagues and Students,
You are cordially invited to UNAM Nanocolloquium seminars focusing on advancements in the field of nanoscience and nanotechnology. The seminars bring us the most recent developments in these exciting fields.
The 5th talk of this term will be presented by Assoc. Prof. João F. Mano*
Title: Nano-multilayered polymeric assembled systems in hierarchical devices for biomedical applications
Date: March 04, 2016 (Friday)
Place: UNAM Conference Room
ABSTRACT – Nanostructured multilayered films have been often fabricated using the layer-by-layer technology, where sequential layers of macromolecules are well stabilized by electrostatic interactions or other weak forces. Using adequate templates, non-flat coatings can be fabricated with tuned compositions along the build-up assembly. This enables the production of very well controlled multifunctional and structural devices using mild processing conditions that could be useful in biomedicine, including in tissue engineering or in drug delivery. In such applications, where there is a direct interaction between the implant with tissues and cells, the biomaterials must exhibit adequate surface characteristics, both at the chemical and topographic points of view. Examples of structures having nano-stratified multilayered organizations as building-blocks are presented, based on the use of natural or biomimetic macromolecules. Functional and bio-instructive multilayers may be produced by introducing special chemical groups or bioactive agents in the assembly. Such elements may be then hierarchically organised into 3-dimensional systems for cell colonisation (e.g. capsules or scaffolds) with tuned structural and geometrical control.
