TAT-modified self-assembled cationic peptide nanoparticles as an efficient antibacterial agent

The increasing emergence of drug resistant pathogenic bacteria poses a great challenge to clinical therapy and a threat to public health. Cationic peptides have received great attention for their unique antibacterial mechanism and ability to combat drug-resistant bacteria. In this study, we designed a TAT-modified cationic peptide PA-28 which self-assembled into nanoparticles of about 150 nm. These nanoparticles showed strong antimicrobial...
