They can be designed to specifically target cancer biomarkers, allowing for highly sensitive and accurate detection of cancer cells or molecules associated with cancer. Gene therapy: Nanocarriers, such as lipid nanoparticles or polymer nanoparticles, can deliver therapeutic genes to cancer cells. This approach aims to modify the genetic makeup ...
Nanoparticles of natural polymers such as chitosan are commonly used adjuvants in modern vaccine formulations. [63] Ceria nanoparticles appear very promising for both enhancing vaccine responses and mitigating inflammation, as their adjuvanticity can be adjusted by modifying parameters such as size, crystallinity, surface state, and stoichiometry.
Polymer-drug conjugates are drug molecules held in polymer molecules, which act as the delivery system for the drug. Polymer drugs have passed multidrug resistance (MDR) testing and hence may become a viable treatment for endocrine-related cancers. A cocktail of pendant drugs could be delivered by water-soluble polymer platforms.
It can be directed to the location of cancer cells with sustained release behavior. Studies have also been done on gold nanoparticle responses to local near-infrared (NIR) light as a stimuli for drug release. In one study, gold nanoparticles functionalized with double-stranded DNA encapsulated with drug molecules, were irradiated with NIR light.
Polymeric nanoparticles may also contain beneficial controlled release mechanisms. Polymer Branch. Nanoparticles made from natural polymers that are biodegradable have the abilities to target specific organs and tissues in the body, to carry DNA for gene therapy, and to deliver larger molecules such as proteins, peptides, and even genes.

Medical research for cancer begins much like research for any disease. In organized studies of new treatments for cancer, the pre-clinical development of drugs, devices, and techniques begins in laboratories, either with isolated cells or in small animals, most commonly rats or mice. In other cases, the proposed treatment for cancer is already ...
When the blood vessels form so rapidly, large fenestrae result that are 100 to 600 nanometers in size, which allows enhanced nanoparticle entry. Further, the poor lymphatic drainage means that the large influx of nanoparticles are rarely leaving, thus, the tumor retains more nanoparticles for successful treatment to take place. [8]
In prostate cancer, the androgen receptor (AR) plays a critical role in progression of the cancer. Lipid nanoparticles (LNPs) are being considered for delivering siRNA to silence AR. The most effective LNP to be found in vivo contains an ionizable cationic lipid 2,2-dilinoleyl-4-(2-dimethylaminoethyl)-[1,3]-dioxolane (DLin-KC2-DMA). [4]
