1. A portable, hand-held device for electrospinning or electrospraying toward a deposit surface a predetermined solution formulated for the device, the device comprising:
a durable portion; and
a consumable portion coupled to the durable portion, the consumable portion being detachable from and re-attachable to the durable portion;
wherein the consumable portion includes:
a housing,
a conducting rod disposed within the housing and arranged along an axial direction of the device,
an electrode,
a hollow nozzle configured to output the solution from a nozzle tip thereof, the hollow nozzle defining a first portion of a flow path of the solution to outside the device and the nozzle tip defining a second portion of the flow path, and
a consumable housing disposed within the housing of the consumable portion and configured to contain a predetermined maximum volume of the solution and output the solution to the hollow nozzle,
wherein the durable portion includes:
a drive mechanism configured to cause solution from the consumable housing to be output to the hollow nozzle, and
a user control interface configured to receive manual input from a user to control the drive mechanism and application of a high voltage to the electrode to create an electric field for application to the solution to electrospin or electrospray the solution from the hollow nozzle toward the deposit surface,
wherein circuitry is configured to provide the high voltage to the electrode, and
wherein the conducting rod is arranged radially outward of the consumable housing configured to contain the solution.
