Aerosol exposure biotesting for package integrity testing
… hour incubation period. Pouch contamination via microbial ingress was significant (P < .05) for test organism motility (motile) and concentration (10<sup>6</sup> cells/mL).

Determination of the Leak Size Critical to Package Sterility Maintenance
… relationship between loss of sterility due to microbial ingress in test cells and the initiation of liquid flow were found (p < 0.05). Microbial ingress was not found in test cells with microtube IDs of 2 m. Leak sizes critical to the sterility maintenance were found to be different based on …

Epithelial Cell Adhesion and Proliferation on Titanium(V) Biofunctionalized with Nanoceramic Thin Film
… sealing, making the crestal bone vulnerable to microbial invasion. Purpose: To evaluate the effects of atomic layer deposition (ALD) of ZrO2-TiO2 nanoceramic thin film coating, with and without ultraviolet C (UVC) irradiation, on titanium(V) surface hydrophilicity, and adhesion and proliferation …

Predicting Package Defects: Quantification of Critical Leak Size
… leak size is the size micro-defect that allows microbial penetration into the package. The critical leak size of air-filled defects was found to be 7 μm at all pressures tested. This size is considerably important to food packagers because this is when sterility of the package is lost. Previous …
