This method demonstrates a novel test system for detecting influenza A virus using aptamer technology, highlighting its potential applications.
A method for immobilizing DNA aptamers on the surface of a porous polyethylene terephthalate substrate and gold nanoparticles has been developed, preserving the functionality of the recognition elements. The possibility of assembling a ternary complex composed of aptamer-functionalized porous polymeric substrate, influenza A virus, and aptamer-functionalized gold nanoparticles is shown. These results can be used to create aptamer-based test strips.
