Cancer is one of the most serious health concerns in 21st century whose prevalence is beyond boundaries and
can affect any organ of human beings. The conventional chemotherapeutic treatment strategies lack specificity to tumours
and are associated with toxic effects on immune system and other organ systems. In the past decades, there has been a
continuous progress in the development of smart nanocarrier systems for target specific delivery of drugs against variety
of tumours including intracellular gene-specific targeting. These nanocarriers are able to recognize the tumour cells and
deliver the therapeutic agent in fixed proportions causing no or very less harm to healthy cells. Nanosystems have
modified physicochemical properties, improved bioavailability and long retention in blood which enhances their potency.
A huge number of nanocarrier based formulations have been developed and are in clinical trials. Nanocarrier systems
include polymeric micelles, liposomes, dendrimers, carbon nanotubes, gold nanoparticles, etc. Recent advancements in
nanocarrier systems include mesoporous silica nanoparticles (MSNs), metal organic frame works and quantum dots. In the
present review, various nanocarrier based drug delivery systems along with their applications in the management of
cancer have been described with special emphasis on MSNs.
