The Science of Molecular Engineered Materials

The medical advances that Molecular Engineered Material such as the MET platform bring are only possible because of Nanomerics' scientific and technological advances in:

  • polymer synthesis

  • polymer analytical methodology

  • nanoparticle fabrication

  • nano-scale analytical processes

Chemical engineering to control material properties

Drug - Particle Molecular Dynamics 

Chemoinformatics tools guided engineering

Nanomerics proprietary Molecular Engineered Materials are based on world leading know-how and scientific leadership in polymer nanotechnology.

Tight control of the chemical modifications of natural polymers is key to being able to control polymer physical chemistry precisely. Advances in analytical methodology developed by Nanomerics are necessary in order to confidently measure the relevant parameters. 

Specifically, our expertise enables the fabrication of nano-scaled polymer aggregates which interact with drugs or biological molecules in a controlled fashion.

The biocompatible polymers are tailored to form containers that package the drug and carry it across epithelial barriers to the target site and thus overcome delivery problems.
