Research lines

The lines of research of our group in the field of dendrimers try to use these materials as a tool to confer directionality to some of the properties and applications of dendrimers in Biomedicine and Advanced Materials. This provides an additional property that may be essential in those cases in which anisotropy and self-organization are fundamentals.

In the field of Biomedicine our group has focused on the synthesis of three types of fundamental structures:

  • Dendrimers self-organizing into solid nano-structures for applications as drugs, transporters of drugs and in gene transfection.

  • Liposomes and vesicles based on liquid crystal dendrimers that respond to external stimuli for the controlled release of drugs.

  • Photochromic liquid crystal dendrimers for applications as biosensors.

 

The main objectives are:

  • Objective 1: Design and synthesize new biocompatible dendrimers for gene transfection (DNA and SiRNA).

  • Objective 2: To study the activity of nanoaggregates formed with three types of dendrimeric platforms, pseudodendrimers, Janus type dendrimers and linear dendritic structures, as smart transporters for the controlled release of active drugs against malaria, tuberculosis and hepatitis C.

  • Objetivo 3: To advance in the knowledge of the structure-activity relationship in these materials through the quantitative study of the interaction between drugs and dendrimers using the Isothermal Calorimetry (ITC) technique.
