Among the many scientific advances to come from the study of nanoscience, the
development of ligand-targeted nanoparticles to eliminate solid tumors is
predicted to have a major impact on human health. There are many reports
describing novel designs and testing of targeted nanoparticles to treat cancer.
While the principles of the technology are well demonstrated in controlled lab
experiments, there are still many hurdles to overcome for the science to mature
into truly efficacious targeted nanoparticles that join the arsenal of agents
currently used to treat cancer in humans. One of these hurdles is overcoming
unwanted biodistribution to the liver while maximizing delivery to the tumor.
This almost certainly requires advances in both nanoparticle stealth technology
and targeting. Currently, it continues to be a challenge to control the loading
of ligands onto polyethylene glycol (PEG) to achieve maximal targeting.
Nanoparticle cellular uptake and subcellular targeting of genes and siRNA also
remain a challenge. This review examines the types of ligands that have been most
often used to target nanoparticles to solid tumors. As the science matures over
the coming decade, careful control over ligand presentation on nanoparticles of
precise size, shape, and charge will likely play a major role in achieving
success.
