Abstract
Cancer is one of the leading causes of death worldwide, affecting the entire
world irrespective of demographic and economic variations. In the last few decades,
development concerning cancer diagnosis and treatment has witnessed significant
advancement but still lags far behind in terms of targeted delivery to the targeted site
without much adverse effect. Changes in the structure and pathophysiology of cancer
tissue, like leaky vasculature, pH, temperature, over-expression of certain receptors,
etc., are being utilized for the development of different approaches of targeted drug
delivery to such tissues avoiding the adverse effects associated with cancer
chemotherapy. The utilization of enhanced permeability retention (EPR) and surface
modification of the nano-sized formulation with different ligands, such as proteins,
aptamers, antibodies, etc., are some common ways used for the above.
The current chapter includes the different nano-carriers used for targeted drug delivery
of medicaments to the affected site along with their surface modification which has
shown their significance in the management of cancer.
