Size measurement |
 |
Measurement of droplet size distributions in emulsions provides stability data long before macroscopic instability can be assessed. |

The clear zones of the Petri dish show bacteria that were inactivated by an antimicrobial substance.
The zones' areas were linearly correlated to the concentration of antimicrobial substance. |

Counting |
 |
| |
The image above shows the number of "alive" Erythrocytes in five formulations.
Three of them contained various concentrations of antimicrobial substance. |
| |
The other two contained this substance enclosed in particles that were selectively targeting bacteria. |
