Drug delivery is a rapidly growing area that is now taking advantage of nanotube technology. Systems being used currently for drug delivery include dendrimers, polymers, and liposomes, but carbon nanotubes present the opportunity to work with effective structures that have high drug loading capacities and good cell penetration qualities.
pH-triggered drug delivery systems are able to control the pharmacokinetics and the biodistribution of the drugs enclosed within the drug carrier and have a controlled release. Many “smart” pH-responsive drug delivery systems have not made it to clinical trials. [27] However, there still are many challenges with this treatment method. [10]
Developments in targeted drug delivery to tumors have provided the groundwork for the burgeoning field of targeted drug delivery to cardiac tissue. [5] Recent developments have shown that there are different endothelial surfaces in tumors, which has led to the concept of endothelial cell adhesion molecule-mediated targeted drug delivery to tumors.
However, the modalities can be combined; antibody-drug conjugates combine biologic and cytotoxic mechanisms into one targeted therapy. Another form of targeted therapy involves the use of nanoengineered enzymes to bind to a tumor cell such that the body's natural cell degradation process can digest the cell, effectively eliminating it from the ...
T-cell transfer therapy: a treatment that takes T-cells from the tumor and selects or changes them in the lab to better attack cancer cells, then reintroduces them into the patient. Monoclonal antibodies: designed to bind to specific targets on cancer cells, marking cancer cells so that they will be better seen and destroyed by the immune system.
Angela Zhang (born 1994) is an American scientist who in 2009, at the age of fourteen, began to research at Stanford University. [1] [2] By 2011, Zhang's research won the $100,000 Siemens Competition in Math, Science & Technology, and earned her widespread notability [3] [4] [5] for her research on cancer treatments with iron oxide gold nanoparticles.
Physical activity before cancer diagnosis is associated with a decreased risk of cancer progression and death, a new study, which focused mostly on breast and prostate cancer patients, found.
Nanocarriers are useful in the drug delivery process because they can deliver drugs to site-specific targets, allowing drugs to be delivered in certain organs or cells but not in others. Site-specificity is a major therapeutic benefit as it prevents drugs from being delivered to the wrong places.
