Scientists who dedicate their research activity to biomaterials pass through the typical
dichotomy that often characterizes the basic research.
On one side is the wish of exploring new frontiers of chemistry, physics, biology,
medicine, pharmaceutics and all other disciplines to which biomaterials can be
applied. Constantly improving of scientific knowledge would feed the freedom of
attempting new strategies for producing materials with always tailored and improved
Nhóm nghiên cứu Cirimat (1) do Emmanuel Flahaut đứng đầu đã liên liên kết với nhiều phòng thí nghiệm Toulouse (2) và một đơn vị Inserm ở Bordeaux để nghiên cứu ảnh hưởng của các ống nano carbon đến sức khoẻ con người và môi trường.
Absorption of light (W or visible) by the ground state of a molecule (So) generates
electronically excited states, either directly (the singlet states) or after intersystem crossing
from the singlet manifold (the triplet states). Alternatively, triplet states may be generated by
energy transfer from another excited state (a sensitiser). In both multiplicities, very fast
internal conversion leads to the lowest states (S1 and TI respectively). These states, although
still quite short lived (typical lifetime 610-8 s for S1 and ...
Products of nanotechnology are expected to revolutionize
modern medicine, as evidenced by recent scientific advances
and global initiatives to support nanotechnology and nanomedicine
research. The field of drug delivery is a direct beneficiary
of these advancements. Due to their versatility in
targeting tissues, accessing deep molecular targets, and controlling
drug release, nanoparticles are helping address challenges
to face the delivery of modern, as well as conventional
With parallel breakthroughs occurring in molecular biology and nanoscience/technology, the newly
recognized research thrust on “nanomedicine” is expected to have a revolutionary impact on the
future of healthcare. To advance nanotechnology research for cancer prevention, diagnosis, and
treatment, the United States National Cancer Institute (NCI) established the Alliance for
Nanotechnology in Cancer in September 2004 and has pledged $144.3 million in the next five years

or insufficient. This is attributable, in large part, to differences in the types of interventions and, subsequently, in the mix of results. Looking closely within categories of design features, however, the following specific design features seemed to improve comprehension for low-health-literacy populations in one or a few studies: (1) presenting essential information by itself (i.e., information on hospital death rates without other distracting information, such as information on consumer satisfaction); (2) presenting essential information first (i.e.
