Strategic Focus

Student training. Performing primary and applied research on organic, inorganic, and hybrid materials, such as:

Biodegradable and/or biocompatible polymers to prepare nanomaterials for the transportation and controlled delivery of drugs or enzymes.

Synthetic polymers to produce membranes for fuel and solar cells.

Inorganic materials to be used in the preparation of cathodes or anodes of rechargeable batteries for use in electric transportation. 

Research Areas and Topics

  • Porous and non-porous nanomaterials.         
  • Synthesis, characterization, and application of biodegradable polymers.   
  • Synthesis, characterization, and modification of synthetic polymers.    
  • Characterization of materials.     
  • Immobilization of enzymes, peptides, and related.

Notable Projects

  • Preparation and characterization of Gusperimus carrier nanoparticles with potential application in the process of islet cells implantation for the treatment of type 1 diabetes mellitus.
  • Study on the effects of nanotransported polyphenols and cannabinoids as a therapeutic application in an in vitro and in vivo oxidative stress model of Alzheimer and Parkinson disease.
  • Preparation of composite membranes from functionalized mesoporous silica nanoparticles and sulfonated poly (ether ether sulfone) with potential application in methanol fuel cells.
  • Preparation of solid antimicrobial biomaterials through immobilization of KR-12 peptide and analogs in siliceous materials and assessment of their behavior in fibrin gel for dressings.

Main Research Results

  • Polymeric nanoparticles where various active principles showing no cytotoxic effects, good encapsulation efficiency, and controlled delivery have been encapsulated.
  • Polymeric membranes of ion exchange to be used in fuel cells, with low water retention, low methanol permeability, and proper phase separation with presence of channels inside the membrane.
  • Electrodes to be used as cathodes and anodes.
  • Hybrid materials to be used as support for enzymes, peptides, and others.
