Researchers watch in real time as fat-encased drug nanoparticles invade skin cells

19.10. 2017 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Some anti-cancer drugs are encapsulated to allow gradual release, spreading their effect over a longer time. For example, one formulation of the chemotherapy doxorubicin (the FDA-approved drug Doxil) encloses molecules of the drug in fatty nano-spheres called liposomes, which allows the drug to circulate longer in the blood. However, the use of liposome "capsules" often comes with side-effects. Unfortunately, liposomes often end up in skin cells, resulting in rash and even lesions. These side effects can be "dose-limiting," meaning that the amount of medicine that can be used is limited by the severity of side-effects. If researchers could decrease the side-effects of liposome use, doctors could use higher doses of these drugs, perhaps leading to better cancer control.

New microcapsules to enhance the efficiency of genome-editing

06.10. 2017 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Researchers from Tomsk Polytechnic University jointly with their colleagues from St. Petersburg, Hamburg and London have found that polymer and hybrid silica-coated microcapsules are more efficient in genome-editing when applying CRISPR-Cas9. In the future, this joint development will significantly simplify and increase the efficiency of genome editing, which can treat previously irremediable inherited diseases such as Alzheimer's, hemophilia and many others.
