example 1
[0158]This example describes the inactivation of bacteria on a human hand from a brief spraying of a pathogen inactivating fluid and then rapid drying.
[0159] A stock solution of Escherichia coli K-12 strain (from Carolina Biological Supply, Burlington, NC) was obtained and diluted 10,000-fold in Nutrient Broth (from Carolina Biological Supply, Burlington, NC) to produce Diluted bacterial solution. In this example, 25 μL of the diluted solution was pipetted onto the pads of the index, middle, and ring fingers of a human hand. After pipetting, the solution was spread with the pipette tip and dried under a small air blower (Delta model BFB0712HH-A, Digi-Key Corporation, Thief River Falls, MN) for several minutes. Based on bacterial plate counts from the same batch of solutions, it was estimated that this 25 μL solution contained 70 to 100 bacteria, as described in Example 4 below. After drying, aqueous hydrogen peroxide solution (3.0% concentration) was sprayed for 1 second ...

[0161] This example describes the inactivation of bacteria on a human hand from a brief spraying of a pathogen inactivating fluid and then rapid drying.
[0162] A solution of E. coli K-12 strain was obtained and diluted 10,000-fold in nutrient broth to produce a diluted bacterial solution. All biological supplies were sourced from Carolina Biological Supply, Burlington, NC. In this example, 5 μL of this diluted solution was pipetted onto the pads of the index, middle, and ring fingers of a human hand. After pipetting, the solution was pipetted and dried under a small air blower for a few minutes, as described in Example 1. Based on bacterial plate counts from the same batch of solutions, it was estimated that this 5 μL solution contained 15 to 20 bacteria, as described in Example 4. After drying, aqueous hydrogen peroxide solution (3.0% concentration) was sprayed for 1 second onto the middle and ring finger pads of the index, middle and ring fingers previously treated with ...
example 3
[0164] This example describes a test to determine the amount of water deposited with an airflow-based atomized spray system and dried with a small air blower.
[0165] The amount of water deposited from the spray gun and the amount of drying that occurs within 5 seconds of exposure to the air stream from a small blower was evaluated on a 25mm diameter track etched polycarbonate film with 0.4um diameter holes (from Missouri Whatman Cyclopore, St. Louis, Model 7060-2504). The spray gun and small blower used in this example are described in Example 1. The initial weight of the film was measured using a precision balance (Sartorius model CPA64 from Bohemia, NY). After initial weighing, the membrane was placed on a polycarbonate support block and held by the weight of a polycarbonate plate comprising three holes penetrating 16.3 mm in diameter. The plate was placed such that one of the vias was concentric with the membrane. The film was then thinly coated with water for about 1 ...
