From: Ultra-rapid elimination of biofilms via the combustion of a nanoenergetic coating
Biofilm type | Method used for biofilm elimination | Log reduction in CFU count | Time taken |
---|---|---|---|
P. aeruginosa and S. aureus | Cleaning with detergents, followed by high-pressure wash and mechanical scrubbing [11] | < 3 | 20 min soak detergent + 1 min wash + <1 min scrub |
P. aeruginosa and K. pneumoniae | Treatment with multiple chemicals (chelating agents, hypochlorites etc.) [12] | 1–3 depending on chemical used | 1 hr |
Pseudomonas fluorescens | Combination of Enzymes (proteolytic + polysaccharide-degrading enzymes) [13] | 2-4 | 2 hrs |
P. aeruginosa, S. epidermidis, and S. aureus | Ultrasound [15] | 1.02 – 1.48 | 10 minutes |
E. coli and S. aureus | Chelating Agents (EDTA / EGTA) and Ultrasound [14] | ~ 2 | Unknown soak time; 10–60s sonication |
Pseudomonas aeruginosa | Biocides (Chemicals) + Electric Field [16] | 3 | 12 hours |
E. coli | High Pressure CO2 / N2 aerosols [17] | 1-2 | 90 s |
P. aeruginosa | Our Method (Rapid combustion of a sprayed on layer of nano-energetic materials) | > 5 | ~ 1 min spray; < 1 s burn |
