Abstract
Abstract: The development of novel colloidal formulations that can regulate the pharmacological and biological properties of medications has been made possible by the developments of nanotechnology. Biodegradable nanoparticles were exploited as drug delivery methods because of their high bioavailability, improved encapsulation, controlled release, and less toxic characteristics. Over the past few decades, a variety of synthetic polymers have been investigated for application in nanomedicine, particularly in drug delivery systems. Drug delivery polymers need to be environmentally friendly, biodegradable, and biocompatible. As they have the ability to provide targeted delivery to a specified site, polymeric nanoparticles have the potential to increase the effectiveness of cancer therapies significantly. It is possible to modify the physical and chemical characteristics of polymers to provide delivery across the many biological barriers needed to reach different cell subsets. The use of biodegradable polymers as nanocarriers is particularly appealing since these materials can be developed to show triggered functionality at certain locations or activated by an external source in addition to degrading under physiological circumstances. Biodegradable polymers can be developed as easy drug-delivery systems that specifically target the tumour microenvironment. This is because these nanomedicines can directly target cancer cells, as well as blood vessels that supply the nutrition and oxygen required for tumour growth and immune cells that support anti-cancer immunotherapy. With the advancements in nanotechnology-based drug delivery systems for pharmaceutical applications, it is exciting to examine and highlight the significance of polymeric nanocarrier systems for drug delivery in chemotherapy.
