GOLD NANOSHELLS: A REVIEW ON ITS PREPARATION CHARACTERISATION AND APPLICATIONS
Mr. Jadhav Nikhilesh*, Mrs. Karpe Manisha, Dr. Kadam Vilasrao
ABSTRACT Gold nanoshells are spherical particles with diameters typically ranging in size from 10 to 200 nm. They are composed of a dielectric core covered by a thin gold shell. As novel nanostructures, they possess a remarkable set of optical, chemical and physical properties, which make them ideal candidates for enhancing cancer detection, cancer treatment, cellular imaging and medical biosensing. Gold nanoshells are unique in that they combine many ideal features in a single particle. As a direct result of nanoscale resonance phenomena, gold nanoshells have very large optical absorption and scattering cross - sections, which render them highly suitable as contrast agents for imaging. Keywords: Gold nanoshells, Self assembeled monolayers (SAMs) , surface plasmon resonance (SPR), Alkanethiol funtionization. [Download Article] [Download Certifiate] |
