Time cut from days to hours – Cancer drug delivery

August 12th, 2008 | No Comments | Posted in Cancer

CWRU’s researchers that are focused on cancer research have gone a step further by developing a technique that is able to deliver anti-cancer drugs to it’s targets within hours. It is a huge advance since the current time needed to perform such an action is 2 days.

All of the research was done on a laboratory mice. If this model would be applied to humans, it would surely benefit the patients since the time is significantly reduced.

Clemens Burda, director of the Center for Nanomaterial research at Case Western Reserve University and Yu Cheng, a graduate student have published a paper in the Journal of the American Chemical Society discussing this subject.

The model actually uses gold nanoparticle vectors to deliver PDT drugs to the target. „Gold nanoparticle vectors aren’t usually used in PDT, but since the gold is nontoxic and inert, we used it.“ said Cheng.

PDT (Photodynamic therapy) uses drugs that are sensitive to light. When they get exposed to light, they energize and burn the cancer cells away. Of course, PDT patients have to stay away from bright lights for days.

This research was funded by the National Institute of Health, Biomedical Research Technology Transfer Center and the National Science Foundation.

How can nanotechnology improve drug delivery

August 7th, 2008 | No Comments | Posted in Nanomedicine News

99% of drug molecules that patients take don’t reach their final destination. Apart from missing their target, they don’t even leave the body – they just stay there. This is a big problem since many of these molecules (especially those used to treat cancer and such) are toxic. That’s why many researchers are working on improving the drug delivery process. Of course, nanotechnology (nanomedicine) is the way to go.

The research shown in the video is focused on developing a nanotech device which will be able to carry a certain drug to it’s target, be monitored throughout it’s journey and finally, get delivered without being destroyed by body’s natural defence lines. Stealth design is the answer…


The International NanoScience Community

August 6th, 2008 | No Comments | Posted in Other

The International NanoScience Community (http://www.nanopaprika.eu) is a website founded in November 2007. It is totally dedicated to the worldwide NanoScience community. You can share your stuff with the world here: photos, videos, art, thoughts, discussions — everything that’s got to do with nano.

András Paszternák is the creator and editor of The International NanoScience Community. András is a chemistry PhD student in Budapest, Hungary. The community started by focusing on the Hungarian audience, but then turned global. The community currently contains more than 950 members, researchers, students, industrial partners from Europe, India, USA and 50 other countries.

The community is fully equiped with various functions like chat, scientific forum, 26+ thematic groups (SPM, nanotoxicity, etc), photos, videos, e-shop, games and so on. Hence, it’s definitely a good website for members to discuss, share infomation and develop ideas.
