Abstract

DNA aptamers specifically recognizing microbial cells and viruses have a range of analytical and therapeutic applications. This article describes recent advances in the development of aptamers targeting specific pathogens (e.g., live bacteria, whole viral particles, and virally-infected mammalian cells). Specific aptamers against pathogens have been used as affinity reagents to develop sandwich assays, to label and to image cells, to bind with cells for flow-cytometry analysis, and to act as probes for development of whole-cell biosensors. Future applications of aptamers to pathogens will benefit from recent advances in improved selection and new aptamers containing modified nucleotides, particularly slow off-rate modified aptamers (SOMAmers).
