How can I prevent attachment of nanoparticles to plastic surfaces ?

23 February 2023 1 9K Report

I am radiolabeling silica nanoparticles with a certain radioistope, however after purification I found that the activity was still in the eppendorfs, means that my particles get stuck to the tubes, although I am using low adhesion eppendorfs.

So what is the best way to prevent adhesion ? coating with hydrophilic polymers to polysterens ? and how to do so ?

even though I tried using low-adhesion eppendorfs, DNase, RNase free
