1. A portable ES device comprising:
a device barrel, wherein said device barrel is comprised of a first end and a second end;
a spinneret encapsulated by said device barrel, wherein said spinneret is located in proximity to said first end of said device barrel;
a conductive electrode located in proximity to said second end of said device barrel, wherein an electrostatic field is produced between said spinneret and said conductive electrode; and
a crossflow system comprised of a first perpendicular opening of said device barrel, where an air flow stream, directs electrospun material from said spinneret to a surface or substrate through a second perpendicular opening of said device barrel.
