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.
A pH/magnetic field dual responsive drug loaded nanomicelle was developed for targeted magnetothermal synergistic chemotherapy of cancer. In this drug delivery system, after the drug reaches the target site and tumor cell uptake is complete, an external magnetic field is applied causing a magnetothermal effect, raising the tumor cells ...
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.
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]
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.
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 ...
An existing cancer drug has shown promise in halting Parkinson's disease progression in mouse models. More research is needed to confirm these findings. Could an FDA-approved cancer drug help stop ...
Bioprinting drug delivery is a method for producing drug delivery vehicles. It uses 3D printing of biomaterials.Such vehicles are biocompatible, tissue-specific hydrogels or implantable devices. 3D bioprinting prints cells and biological molecules to form tissues, organs, or biological materials in a scaffold-free manner that mimics living human tissue.
