Embed tiny solar cells in your body to fight cancer

Illustration for article titled Embed tiny solar cells in your body to fight cancer

By bringing the field of photovoltaics into medicine, researchers hope to create a far more precise method of drug delivery for fighting cancer. That's right - this cancer cure involves tiny photovoltaic particles like the kind used in solar cells.

One of the major drawbacks of chemotherapy is that it damages far more of the body than just the malignant tumors it's used to fight. In order to target just the cancerous areas, and not hit everything on the way there, researchers from the University of Texas in El Paso created a tiny solar cell. They attached model drugs to each side of the cell, one of which was positively charged, the other negatively. Once the tiny solar devices are in the body, they're targeted with an infrared or laser light blast, causing it to release the drugs.

This would mean the medication would only be released at a specific juncture, and could be used to deliver the medical payload extremely specifically, and altering the intensity of light would control how much of the drug would be released.

At present, this work is just a proof of concept, and has a significant amount of work to go. We reported on a similar technique in November using fuzzy nanocubes.

As someone who is at high risk for cancer, I approve. I just hope wherever they do the procedure looks like the bridge of the Enterprise, and JJ Abrams performs it.
