Spatial distribution of bacteria, bacteriophages and nano-emulsion droplets is identified.
•
Bacteriophages are ‘shielded’ against external factors by nano-emulsion droplets, and hence become more stable.
•
Zeta potential measurements elucidate the mechanism of enhanced infectivity.
•
Nano-emulsions eliminate electrostatic repulsion between bacteria and bacteriophages.
•
Nano-droplets stimulate more effective bacteria/bacteriophage interaction which results in an enhanced killing effect.
