Nanotechnology and Biomedicine(4)

Yamamoto discusses the new contributions of nanotechnology in com- parison to existing methods to release, target, and control drug delivery inside the human body. Self-assembly and self-organization of matter offer new pathways for achieving desired properties and functions. Exploiting nanoparticle sizes and nanosized gaps between structures represent other ways of obtaining new properties and physical access inside tissues and cells. Quantum dots are used for visualization in drug delivery because of their fluorescence and ability to trace very small biological structures. The secondary effects of the new techniques include raising safety concerns such as toxicity that must be addressed before the techniques are used in medical practice.
