Nanotechnology and Medicine

Abstract

Diseases and ill-health are caused by damage
at the molecular and cellular level, which
gradually multiplies affecting the system as a
whole. The medicine/drug consumed to cure a
particular ailment has to survive a long journey
through the stomach and reach the intestine intact
and then come into circulation crossing the
intestinal wall. Once in blood, it gets filtered
through the liver and travels through the body
resisting acids of digestive juices, jump membrane
barriers and then act on specified area of damage
in the system. The challenges in the existing
medicinal systems are for protein-based
pharmaceuticals which are broken down when
taken orally, killer diseases are growing more
resistive to drugs, surgical tools are large and
crude much suited to tear and injure rather than
heal and cure [1]
