Research Interests

At the Laboratory of Microheterogeneous Systems of ITQB NOVA we study the structure and topology of lipid aggregates and the kinetics of bimolecular reactions in lipid mesophases. The lipid mesophases we are interested in are those that mimic biological structures such as the cell membranes or the stratum corneum lipid matrix.

In our kinetic studies the progression of reactant interaction in the micro-millisecond time scale is simulated by Monte-Carlo methods. The objective is to develop more realistic models for biological reactions occurring between membrane components. In the studies of the structure of lipid mesophases the purpose is to improve the present knowledge about lipid molecular interactions. The experimental structural data of lipid mesephases is compared with the predictions of the generally accepted lipid interaction theories, their drawbacks criticized and eventually corrected.

Sistemas Micro-heterogéneos (PT)

Um dos objectivos do trabalho do Laboratório de Sistemas Micro-heterogéneos é o estudo das propriedades químico-físicas de membranas lipídicas nomeadamente a obtenção de parâmetros necessários para simulações in silico. Outro objectivo é o estudo da cinética de reacções entre componentes de membranas biológicas.
