Background: Nanocarriers have been a part of drug delivery for some decades
now. Due to the enormous advantages offered by them, they are replacing the conventionally
Objective: The objective of the current review is to focus wider applications of these
nanocarriers in drug delivery, diagnosis, imaging, and targeting as well. It also focuses on
the different types of nanocarriers, method of preparation, characterization and most advanced
uses or application in medicine.
Methods: Literature has been reviewed intensely. Data from various sources like NCBI
PubMed and other valued journals have been reviewed thoroughly. Various research investigations
related to nanocarriers systems have been compiled.
Results: Selection of the nanocarriers type as well as their composition depends upon the
disease and the application for which it is to be used. Nanocarriers have been investigated
for various diseases such as cancer drug delivery, cardiovascular drug delivery, insulin
delivery, antimalarial drug delivery, central nervous system drug delivery, ophthalmic,
pulmonary and brain delivery, etc.
Conclusion: Nanotherapy has led to the advancement in the delivery of chemotherapeutic
drugs in cancer because of their characteristic enhanced permeation and retention in the
tumor tissue. Also, its applications in various other aspects of therapeutics have been extraordinary
and much more is yet to be explored.
