Atmospheric air plasma induces increased cell aggregation during the formation of Escherichia coli biofilms (2018)
Journal Article
Kwandou, G., Mai-Prochnow, A., Prescott, S. W., Spicer, P. T., & Cullen, P. (in press). Atmospheric air plasma induces increased cell aggregation during the formation of Escherichia coli biofilms. Plasma Processes and Polymers, https://doi.org/10.1002/ppap.201700212

Atmospheric air plasma has previously been shown to be a novel and effective method for biofilm eradication. Here we study the effects of plasma on both microbial inactivation and induced structural modification for forming biofilms. New structures a...

Sampling effects on the quantification of sodium content in infant formula using laser induced breakdown spectroscopy (LIBS) (2018)
Journal Article
Cama-Moncunill, X., Markiewicz-Keszycka, M., Cama-Moncunill, R., Dixit, Y., Casado-Gavalda, M. P., Cullen, P., & Sullivan, C. (2018). Sampling effects on the quantification of sodium content in infant formula using laser induced breakdown spectroscopy (LIBS). International Dairy Journal, 85, https://doi.org/10.1016/j.idairyj.2018.04.014

Laser-induced breakdown spectroscopy (LIBS) was employed to predict the sodium content of infant formula (IF) over the range 0.5–4 mg Na g−1. Calibration models were built using partial least squares regression (PLS), correlating the LIBS spectral da...

Impact of plasma jet geometry on residence times of radical species (2018)
Journal Article
Lalor, J., Scally, L., Cullen, P. J., & Milosavljevi?, V. (2018). Impact of plasma jet geometry on residence times of radical species. Journal of Vacuum Science and Technology A, 36(3), Article 3e+108. https://doi.org/10.1116/1.5022294

Numerous electrode geometries and power supplies, both commercial and in-house, have been employed for the generation of low-temperature atmospheric plasma jets. In this work, the development and operation of a 12 jet nonthermal atmospheric plasma sy... Read More about Impact of plasma jet geometry on residence times of radical species.

Cold atmospheric plasma induces ATP-dependent endocytosis of nanoparticles and synergistic U373MG cancer cell death (2018)
Journal Article
He, Z., Liu, K., Manaloto, E., Casey, A., Cribaro, G. P., Byrne, H. J., …Curtin, J. F. (2018). Cold atmospheric plasma induces ATP-dependent endocytosis of nanoparticles and synergistic U373MG cancer cell death. Scientific Reports, 8(5298), Article 5298. https://doi.org/10.1038/s41598-018-23262-0

Gold nanoparticles (AuNP) have potential as both diagnostic and therapeutic vehicles. However, selective targeting and uptake in cancer cells remains challenging. Cold atmospheric plasma (CAP) can be combined with AuNP to achieve synergistic anti-can...

Characterising the impact of post-treatment storage on chemistry and antimicrobial properties of plasma treated water derived from microwave and DBD sources (2017)
Journal Article
Niquet, R., Boehm, D., Schnabel, U., Cullen, P., Bourke, P., & Ehlbeck, J. (in press). Characterising the impact of post-treatment storage on chemistry and antimicrobial properties of plasma treated water derived from microwave and DBD sources. Plasma Processes and Polymers, https://doi.org/10.1002/ppap.201700127

The biological effects of atmospheric cold plasma generated reactive species are mediated through and at a liquid interface. The diversity of antimicrobial efficacy or intensity of effects may differ with respect to the plasma device or set up, and i...

Efficacy and mechanistic insights into endocrine disruptor degradation using atmospheric air plasma (2017)
Journal Article
Sarangapani, C., Danaher, M., Tiwari, B., Lu, P., Bourke, P., & Cullen, P. (2017). Efficacy and mechanistic insights into endocrine disruptor degradation using atmospheric air plasma. Chemical Engineering Journal, 326, 700-714. https://doi.org/10.1016/j.cej.2017.05.178

Endocrine disruptors are a class of contaminants found in water and process effluents at low concentrations. They are of concern due to their high estrogenic potency. Their presence in the environment has led to the search for effective techniques fo...
