What We Do

Provide a technical solution for the most varied challenges in product development, through the development of customized microcapsules and microscaffolds, creating value to industrial partners and leading to breakthroughs at the scientific and technological level.

  • Disruption at the level of chemical processes for the development of customized active functional microparticles
  • Investigation of innovative material-based approaches in microencapsulation
  • Public and private R&D funding
  • Contribution to an R&D ecosystem:
    • interdisciplinar and international collaborations
    • training talented students (M.Sc. and Ph.D.) and postdocs

A Technology Platform consists on a basic technology that is modified each time to address new challenges.

The Technology Platform on Microencapsulation and Immobilization deals with customized functional microparticles (microscaffolds) or microcapsules, either with hybrid composition, or with hybrid performance. Their custom-tailored morphology, porosity and organic functionality enable the entrapment and/or grafting of a variety of chemical species.

The microcapsules exhibit a controlled release of a specific chemical at a target moment, or condition. The “loaded” matrices (microscaffolds) can be used not only for an application where a slow release of the entrapped compound is needed, but also for an application in which the compound loss is unwanted, i.e. an anchored active chemical is desired.

… different morphologies for varied applications …

Core-shell microcapsule (MC)

Multinucleated microcapsule (MC)


Mesoporous continuous matrix entrapping the active compound


Meso and macroporous matrix to entrap active compounds

… hybrid composition … entrapment of a variety of chemical species ...



Polymerization-Induced Phase Separation within Microspherical Domains

Biocide entrapment within microscaffolds for new anti-fouling coatings

Functional microcapsules for ecological and high performing polyurethane one component foams

Microscaffolds loaded with essential oils for slow perfume release

Encapsulated isocyanate for one component adhesives

On-going Projects

Project ECOBOND: Development of new autoreactive and ecological monocomponent adhesives

Project NANOPOLI: Development of flame resistant nanocomposite

Project ELASTOMREG: Vulcanized thermoplastic elastomer with self-healing properties


Our aim is to create the knowledge base needed to support the ever expanding range of applications. The Platform focuses on deepening the understanding of multiphasic systems (emulsions) stability, reaction engineering, processing and material properties and deals with the implementation of new methods and methodologies to support the development of microcapsules/microscaffolds with customized properties, able to address the industry needs in product development.

Collaborating with us is a cost-effective way for companies to meet their on-going research needs, while, at the same time, addressing challenges that extend beyond their individual research and innovation portfolios. By letting us know your product and process specifications, we will identify the most appropriate core-shell system, particle morphology and fabrication strategy. You just need to email us at ana.marques@tecnico.ulisboa.pt, in order to evaluate the feasibility of the work.

University and companies can jointly work on research topics of common interest, both within and across value chain segments. Private funding, as well as public national and international funding schemes may be employed.

This gives companies the opportunity to accelerate innovation and increase sustainable competitiveness and Universities the opportunity to apply basic and fundamental knowledge to contribute to the economy growth.

Some of the areas where we can play a role:

  • Chemical retention or isolation, enabling the use of incompatible ingredients in the same formulation, e.g. one component foam systems, autoreactive monocomponent adhesives, etc.
  • Self-healing of polymers
  • Chemical retention or isolation of phase change materials (PCMs), of corrosion inhibitors…
  • Flame retardants encapsulation
  • Surface treatments with compatibilizers and multifunctional compounds
  • CO2 capture
  • Chemical immobilization and controlled, or slow release of active species, such as ecological inks with long lasting biocidal properties, slow release of perfumes and essencial oils, etc.
  • etc.

The innovative materials developed in the framework of this Technology Platform address new product development projects that foster a sustainable and cleaner environment, economic growth, people safety and the creation of innovation and knowledge-driven jobs. Research activities are carried out in close contact with industrial partners and technology is transferred accordingly.
