Do bacteria secrete plasmids into extracellular surroundings as part of their natural biological processes?
Are there simple techniques to trigger the release of plasmids while NOT forcing the release of nucleoids?
Perhaps by using a fluorescently tagged peptide/aptamer that specifically binds to the gene of interest (accompanied by noticeable change in emission spectrum / intensity / shift upon successful...
