Título: “Ongoing Organic Synthetic Methodologies@FF.ULisboa”.
Prof. Dr. Carlos A. M. Afonso, University of Lisbon, Portugal.

Abstract: In line with our interest in catalyst reuse [1] and exploring new synthetic methodologies will be described ongoing research in this laboratory on the valorisation of natural resources [2], ionic liquids area [3] and novel catalyzed transformations such as: a) Brønsted acid-catalyzed dihydroxylation of olefins in aqueous medium [4]; b) Asymmetric Rh(II) carbenoid and metal-free C-H insertion of alpha-diazo-acetamides [5], c) Production and isolation of 5-hydroxymethylfurfural(HMF) from carbohydrates [6], d) HMF modification [7] and e) Enzymatic resolution of sec-alcohols [8].

Título: "Analytical Sciences for Diagnostics".
Prof. Anne Varenne, Université Paris Descartes, Paris, France.

Abstract: The design and development of diagnostics implies various expertises among which analytical sciences. First, the choice of selective ligands for ultra-trace target preconcentration/extraction from the matrix is a key point: this choice can be oriented by the physico-chemical characterization of potential ligands, for their further optimized use in diagnostics. Second, the diagnostic can be set up with analytical processes, from the sample pretreatment step to the detection step. In this context, electrokinetic methods represent an interesting tool for designing and developing diagnostics. In our group, we conceive diagnostics for biomedical and environmental applications. We will present here an overview of some projects highlighting this crucial impact of analytical sciences for diagnostics innovations.
