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

Project SOLAR2CLEAN (PTDC/EQU-EQU/1056/2020): Engineered solar light driven photocatalytic systems for wastewater purification
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:
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.
