Fig 3. Mass of particles associated with adult female Aedes aegypti legs or whole bodies (without legs) after a 48-h exposure to nanoparticles via contact with a treated surface.

Mosquitoes were collected in groups of ten and legs were removed. Legs or bodies (without legs) were then homogenized in phosphate buffered saline for 2 h, before RhodamineB content was measured for each treatment group. Standard curves were used to calculate the initial mass of particles associated with mosquitoes. CPH:SA (C:S) particles were observed in association legs than with bodies with legs removed. The opposite trend was observed for CPTEG:CPH (C:C) particles. BD = below detectability.
