Abstract: A small area electrostatic aerosol collector combines electrostatic collection of aerosol particles and electrohydrodynamic spraying of fluid so that a sample collected electrostatically can have fluid applied thereto. The fluid may assist with disaggregation and/or desalinization of biological material collected onto a sample substrate. A controller associated with the collector may control an electrostatic charge device and a spraying device such that the charge device and spraying device may operate in alternating fashion, or the charge device and spraying device may operate simultaneously. Further, mechanical systems are provided, for the disaggregation of particulate clusters collected onto a sample substrate.
