NEW DRUG DELIVERY SYSTEM, "NANO SPONGES".
Date: 4-Jun-2010
A new form of drug administration has shown to be more effective then direct injections.
Eva Harth, assistant professor of chemistry at Vanderbilt, has invented this new method that could change the fight against cancer and other non curable diseases in
our favor, she calls them "Nano Sponges".
Nano sponges like the name implies are molecules that are filled with medication, and that medication is slowly released overtime as the sponge starts to decompose. It works in a way like a microscopic time release pill.
These little sponges are also coated with a special chemical called a "linker" that can only attach itself to the spot that the linker was designed to link to. So this way, they can use a Nano Sponge to hold a cancer medication, and then attach a linker that will only attach to cancer cells.
The effect of it is that the sponge files through the blood stream, finds the tumor, attaches itself to the tumor and does not release until its entire stock of medication has been injected directly on to the tumor and nowhere else.
Normal drugs require the medicine to circulate around the entire body while the sponge would allow it to only disperse at the spots that it's needed because.
Another valuable asset this method has is that certain medicines have a negative effect with water making them difficult or at times impossible to dissolve in the water, so in order to inject it; they must use another chemical that reduces this problem but makes the drug less potent. Nano Sponges do not have this problem because they do not need water in them to hold the medicine.
Another bonus is that unlike other systems that are similar, this new method allows for cost of production by keeping the cross linker chemicals as simple as possible and thus easy to replicate for mass consumption.
Combining this with new forms of vaccinations allows us to deliver new kinds of weapons in a more direct way, so the next step is to try them out and see how effective it is, and if it can stop and prevent tumors from spreading, and even reduce their size.
This new method has shown a tremendous increase of effectiveness in animal studies so it appears that will be entering human studies fairly soon.
