Project Description:

Our research group focus in the synthesis and study of stimuli-responsive organic molecules called lipid dendrimers that by self-assembly in nanoparticles for drug-delivery applications. We are interested in understanding how lipid dendrimers can form these nanoparticles in order to develop a new alternative for therapeutic agents for neurological applications. Our group apply concepts of organic chemistry (synthesis and characterization), analytical chemistry, nanotechnology, supramolecular chemistry among other interdisciplinary areas. We are currently working in lipid dendrimer derivatives used for the encapsulation and delivery of drugs that induce neuroplasticity to treat brain strokes.
