Programmable 3D rigid clathrate hydrogels based on self-assembly of tetrahedral DNA and linker PCR products†
Abstract
A clathrate tetrahedral DNA gel was assembled by combining tetrahedral DNA and rigid linker PCR products to achieve visible detection of Salmonella spp. This method overcame the shortcomings of AuNPs in coloration and enriched the use of tetrahedral DNA for the visible detection of virtually any target concerned with pathogens.
