Drug delivery: The cost for discovering, developing and launching a new drug is being estimated to nearly $1.7 billion (www.phrma.org -2003). For many observers, however, the most promising route to achieve major advances in drug development is not through the design of new more efficient drugs but rather to come up with strategies to deliver them at specific tissue location in human or animals (for example, at a tumor site). The LBN’s main task is to develop new powerful and inexpensive nanomachines “inspired by Nature” that will deliver drug at defined tissue locations and thus greatly optimize the benefits of current therapies while minimizing their toxic effects.
