Triblock copolymer micelles enhance solubility, permeability and activity of a quorum sensing inhibitor against Pseudomonas aeruginosa biofilms (2024)
Journal Article
Kasza, K., Soukarieh, F., Romero, M., Hardie, K. R., Gurnani, P., Cámara, M., & Alexander, C. (2024). Triblock copolymer micelles enhance solubility, permeability and activity of a quorum sensing inhibitor against Pseudomonas aeruginosa biofilms. RSC Applied Polymers, https://doi.org/10.1039/D3LP00208J

Antimicrobial resistance is a threat to public health for which new treatments are urgently required. The capability of bacteria to form biofilms is of particular concern as it enables high bacterial tolerance to conventional therapies by reducing dr...

Synthetic macromolecular peptide-mimetics with amino acid substructure residues as protein stabilising excipients (2023)
Journal Article
Foralosso, R., Kopiasz, R. J., Mantovani, G., Stolnik, S., & Alexander, C. (2024). Synthetic macromolecular peptide-mimetics with amino acid substructure residues as protein stabilising excipients. Journal of Materials Chemistry B, 12, 1022-1030. https://doi.org/10.1039/d3tb02102e

The clinical use of protein and peptide biotherapeutics requires fabrication of stable products. This particularly concerns stability towards aggregation of proteins or peptides. Here, we tested a hypothesis that interactions between a synthetic pept...

Chain-extension in hyperbranched polymers alters tissue distribution and cytotoxicity profiles in orthotopic models of triple negative breast cancers. Biomaterials Science, 11, 6545-6560. https://doi.org/10.1039/d3bm00609c

The therapeutic efficacy of nanomedicines is highly dependent on their access to target sites in the body, and this in turn is markedly affected by their size, shape and transport properties in tissue. Although there have been many studies in this ar...

E-selectin is expressed on endothelial cells in response to inflammatory cytokines and mediates leukocyte rolling and extravasation. However, studies have been hampered by lack of experimental approaches to monitor expression in real time in living c...
