ABSTRACT We report the controlled release of an antimicrobial peptide using enzyme-activatable prodrugs to treat and detect Candida albicans Porphyromonas gingivalis . Our motivation lies in prevalence these microorganisms subgingival area where frequency fungal colonization increases with periodontal disease. This work is based on that both therapeutic induces a color change nanoparticle reporter. was then built into zwitterionic prodrug quenches its activity until activation by protease inherent pathogens interest: SAP9 or RgpB for C. P. , respectively. first confirmed intact has negligible toxicity fungal, bacterial, mammalian cells absent trigger. Next, impact assessed via disk diffusion viability assays showed minimum inhibitory concentration 3.1 – 16 µg/mL, which comparable alone (absent integration prodrug). Finally, design exploited colorimetric detection proteases. When were cleaved, plasmonic nanoparticles aggregated causing limit 10 nM gold 3 silver nanoparticles. approach value as convenient selective sensing protease-induced treatment mechanism bioinspired peptides.
