An ESF – European Medical Research Councils (EMRC) Forward Look report
ESF focuses on science driven collaboration between the best European researchers in all disciplines.
We promote the identification and advancement of leading edge science in Europe in close co-operation
with our Member Organisations. We bring together leading scientists, scholars and funding agencies
to explore new directions in research and to plan and implement European level research collaboration
in a global context. Our main instruments include conferences, scientific foresights, collaboration
programmes and support to outstanding young researchers. ESF also manages COST, an
intergovernmental framework for European co-operation in the field of Scientific and Technical Research.
Integrative Biology is currently a hot topic in the Life Sciences. The potential applications of Integrative Biology will
contribute significantly to maximizing the value of knowledge generated in the biomedical field and the outcome
expected for the public health care system. In this context, the strategy developed by the European Medical
Research Councils (EMRC), one of the five Standing Committees at ESF, aims to:
• foster an interdisciplinary approach towards the Functional Genomics domain embracing all the –omics disci-
plines (including the DNA, RNA, protein and other macromolecules world) and their integration into Systems
Biology;
• focus on biomedical applications emerging from these and related domains, such as Nanomedicine and
Structural Medicine; Molecular Imaging, Genetic Epidemiology and Pharmacogenetics in order to advance the
promising field of Personalized Medicine also qualified as Individualized pharmacotherapy;
• develop translational research to overcome boundaries between basic research/science and clinical applica-
tions (e.g., application of cell and gene therapies in Tissue Engineering and Regenerative Medicine, identifica-
tion and validation of biomarkers and therapeutic/diagnostic tools that will allow the transfer of innovation
through a collaborative public-private process of research and development, etc.). In this respect, special atten-
tion will be paid to therapeutic domains identified as a burden for European citizens1:
– cardiovascular and respiratory diseases
– cancer
– allergic, immunological and infectious diseases
– neurodegenerative diseases including neurosciences and mental health
– diabetes, digestive and renal diseases
– rheumatic diseases, musculoskeletal disorders and skin diseases
– rare diseases for instance through its sponsorship of The European Rare Diseases Therapeutic Initiative
(ERDITI), and specific patient populations like children, the elderly and women.
• gather expertise and advance the methodology for the evaluation of the socio-economic value of research in
the above-mentioned fields.
In addition, further attention has been paid on the identification of related regulatory and ethical issues and to the
promotion of biomedical research to the European general public and political stakeholders. In this respect EMRC
is a permanent observer of the Comité directeur pour la Bioéthique at the European Council and is being involved
in further developments brought by the WHO and EMEA to its recommendation to build an open international reg-
istry for clinical trials.
• develop new partnering to support and leverage these activities, i.e. with European Agencies, intergovernmen-
tal organizations (EMBO), charities, pharmaceutical and biotechnological industries, etc.
Due to the progressive character of these scientific fields, the EMRC portfolio will provide flexibility to cover
newly emerging trends in science in a timely manner.

made of polymer nanoparticles is clearly visible. In order to indicate that the particles are in fact gas-filled, an imperfect capsule with a bump has been carefully selected.
These kinds of particles are the basis for Ultrasound Theranostics: Antibody based microbubble conjugates as targeted in vivo ultrasound contrast agents and advanced drug delivery systems.

Foreword
In early 2003, the European Science Foundation launched its Scientific Forward
Look on Nanomedicine. I am pleased to see the successful conclusion of this
foresight study, which has been the first such exercise focused on medical
applications of nanoscience and nanotechnology. The Forward Look involved
leading European experts and led to a definition of the current status of the field
and debates on strategic policy issues. The recently published Policy Briefing
summarised the recommendations made2.

The funding opportunities available for basic

2. CURRENT STATUS OF NANOMEDICINE RESEARCH AND FORWARD LOOK 23
All the technology based workshops held in Amsterdam from 1 to 5 March 2004 were independently invited to
conduct a SWOT analysis regarding the current status of European activities in the field. There was considerable
consensus across these groups and the results were summarised and presented at the Consensus Conference
held at Le Bischenberg. Below is a summary of the most significant points agreed.
