Gold nanoparticles have, in some ways,
revolutionized the field of medicine because of its
wide spread applications in targeted drug
delivery, imaging, diagnosis and therapeutics
due to their extremely small size, high surface
area, stability, non-cytotoxicity and tunable
optical, physical and chemical properties.
Functionalized gold nanoparticles with various
biomolecules such as proteins, DNA, amino
acids and carboxylic acids have been used in
cancer therapy and provide excellent drug
delivery system. Targeted delivery and
programmed release of therapeutic drugs to the
specific site is achieved by using gold
nanoparticles because they can bear high drug
load and release it to the specific site through
various administration routes and can interact
with cancerous cell. Side effects of conventional
drugs have been minimized by conjugation with
gold nanoparticles and they increase the quality
life of patients.
