Toxicity of polyelectrolyte-functionalized titania nanoparticles in zebrafish (Danio rerio) embryos (2020)
Journal Article
Arabeyyat, Z. H., Al-Awady, M. J., Greenway, G. M., Paunov, V. N., & Rotchell, J. M. (2020). Toxicity of polyelectrolyte-functionalized titania nanoparticles in zebrafish (Danio rerio) embryos. SN Applied Sciences, 2(7), Article 1312. https://doi.org/10.1007/s42452-020-3137-x

We investigated the effects of short-term exposure of bare TiO2NPs and polyelectrolyte-coated TiO2NPs in the 5–25nm size range, at relatively high concentrations (of 500 and 1000mg/L) under light or dark conditions, in D. rerio embryos. The biologica... Read More about Toxicity of polyelectrolyte-functionalized titania nanoparticles in zebrafish (Danio rerio) embryos.

Amplified antimicrobial action of chlorhexidine encapsulated in PDAC-functionalized acrylate copolymer nanogel carriers (2018)
Journal Article
Al-Awady, M. J., Weldrick, P. J., Hardman, M. J., Greenway, G. M., & Paunov, V. N. (2018). Amplified antimicrobial action of chlorhexidine encapsulated in PDAC-functionalized acrylate copolymer nanogel carriers. Materials Chemistry Frontiers, 2(11), 2032-2044. https://doi.org/10.1039/c8qm00343b

We have developed and tested a novel functionalised nanocarrier for chlorhexidine (CHX) which provides a very strong enhancement of its antimicrobial action. The nanocarrier was based on lightly-cross-linked acrylate copolymer nanogel particles loade...

Enhanced antimicrobial effect of berberine in nanogel carriers with cationic surface functionality (2017)
Journal Article
Al-Awady, M. J., Fauchet, A., Greenway, G. M., & Paunov, V. N. (2017). Enhanced antimicrobial effect of berberine in nanogel carriers with cationic surface functionality. Journal of Materials Chemistry B, 5(38), 7885-7897. https://doi.org/10.1039/c7tb02262j

We report a strong enhancement in the antimicrobial action of berberine encapsulated into polyacrylic acid-based nanogels followed by further surface functionalisation with a cationic polyelectrolyte (PDAC). Due to the highly developed surface area,... Read More about Enhanced antimicrobial effect of berberine in nanogel carriers with cationic surface functionality.

Nanotoxicity of polyelectrolyte-functionalized titania nanoparticles towards microalgae and yeast: Role of the particle concentration, size and surface charge (2015)
Journal Article
Al-Awady, M. J., Greenway, G. M., & Paunov, V. N. (2015). Nanotoxicity of polyelectrolyte-functionalized titania nanoparticles towards microalgae and yeast: Role of the particle concentration, size and surface charge. RSC advances, 5(46), 37044-37059. https://doi.org/10.1039/c5ra05577f

We studied the nanotoxicity of titania nanoparticles (TiO₂NPs) of various hydrodynamic diameters and crystallite sizes towards C. reinhardtii microalgae and S. cerevisiae (yeast) upon illumination with UV and visible light. The cell viability was ass...
