Nanogels

Polymer gels are among the most attractive and versatile soft ma terials.  They are present in many everyday products including food and pharmaceutical industry.   Polymer gels typically con- tain large amounts of liquid confined within a flexible network of polymer chains or colloidal particles. Among the different types of gels, all with different properties and applications, microgels are sub-micrometer sized cross-linked polymer particles that can carry or incorporate macromolecules in their network structure. This property, coupled with their “soft” character and the ability to introduce stimuli-responsive characteristics, means that they have many attractive applications, including  drug delivery.

The project “Interactions and collective properties of nanogel/microgel-based soft-matter systems of nanotechnological interest”  (FIS2016-80087-C2-1-P) is a coordinated research project that involves the universities of Jaén and Granada, and is funded by the “Ministerio de Economía y Competitividad” of the Spanish Goverment  (see abstract of the project).
