NANOTECHNOLOGY IN MEDICINE
What Does Nanotechnology Mean?
Nanotechnology is the engineering of functional systems at the molecular scale.
It is the study of manipulating matter on an atomic and molecular scale.
NANOMEDICINE
Nanomedicine ranges from the medical applications of nanomaterials, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology.
Medical use of nanomaterials
Using gold nanoshells to help diagnose and treat cancer.
Using liposome's as vaccine adjuvants and as vehicles for drug transport.
Nanomedical approaches to drug delivery center on developing nanoscale particles.
Protein and peptide delivery
great promise for treatment of various diseases and disorders.
Targeted and/or controlled delivery of these biopharmaceuticals using nanomaterials is an emerging field called nanobio pharmaceutics.
conclusion
Developing nanotechnologies are being pursued for general cellular processes such as ubiquitous signaling pathways that may benefit numerous physiological systems, as well as being targeted toward the particular challenges of specific disorders such as cancer, diabetes mellitus and arteriosclerosis.
Ultimately, every patho physiological process has a molecular origin, and it is
from this basic fact that the tremendous potential of nanotechnology applications to medicine arises.
