Please ignore the signal release. Does anyone know if it’s possible for polymer to wrap around a virus?

Yes, we can concentrate viruses and other objects of interest onto beads using antibody conjugated beads (such as these ones from New England Biolabs - I have no affiliation to any company linked in this post, but do occasionally use their products). This is a process called immuno-precipitation and has been around for a very long time.

This is also the principle behind lateral flow assays, where an antigen (it can be a virus, they are available for e.g. influenza and SARS-CoV-2) is suspended and placed onto the strip, where it crosses an antibody panel and binds to it. This then travels with the liquid front to a second antibody that detects the first and causes a signal of some sort to be released.
