Scientists from the Nano Institute in Utah wrote “Biological evaluation of RGDfK-gold nanorod conjugates for prostate cancer treatment”, published in November 2011 for the Journal of Drug Targeting. In the article, the researchers used Spectra/Por® dialysis tubing to dialyze the gold nanorods.

The researchers demonstrate that surface modifications of the gold nanorods resulted in effective targeted treatment. At the time of writing, the authors of the paper submitted a patent concerning the application discussed in the article.

Abstract: Selective delivery of gold nanorods (GNRs) to sites of prostate tumor angiogenesis is potentially advantageous for localized photothermal therapy. Here, we report the cellular uptake and biodistribution of GNRs surface functionalized with the cyclic RGDfK peptide. Click here to read the article.


Standard Grade Regenerated Cellulose (RC) is a clear, flexible and sturdy dialysis membrane with a “looser” molecular selectivity. This economical membrane is ideal for a broad range of applications in which there is a significant size difference between the MW species being separated.
