Abstract (EN): Oligonucleotides able to hybridize bacterial RNA via in situ hybridization may potentially act as new antimicrobials, replacing antibiotics, and as fast in vivo diagnostic probes, outperforming current clinical methodologies. Nonetheless, oligonucleotides are not able to efficiently permeate the multi-layered bacterial envelope to reach their target RNA in the cytosol. Cationic fusogenic liposomes are here suggested as vehicles to enable the internalization of oligonucleotides in bacteria. Here, we describe the formulation of DOTAP-DOPE liposomes, their complexation with small negatively charged oligonucleotides, and the evaluation of the intracellular delivery of the oligonucleotides in bacteria. This strategy uncovers the potential of performing FISH in vivo for real-time detection and treatment of infections. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
