High-throughput miniaturized screening of nanoparticle formation via inkjet printing (2018)
Journal Article
Styliari, I. D., Conte, C., Pearce, A. K., Hüsler, A., Cavanagh, R. J., Limo, M. J., …Taresco, V. (in press). High-throughput miniaturized screening of nanoparticle formation via inkjet printing. Macromolecular Materials and Engineering, doi:10.1002/mame.201800146. ISSN 1438-7492

The self‐assembly of specific polymers into well‐defined nanoparticles (NPs) is of great interest to the pharmaceutical industry as the resultant materials can act as drug delivery vehicles. In this work, a high‐throughput method to screen the abilit... Read More

New N-acyl amino acid-functionalized biodegradable polyesters for pharmaceutical and biomedical applications (2016)
Journal Article
Taresco, V., Suksiriworapong, J., Styliari, I. D., Argent, R. H., Swainson, S. M., Booth, J., …Garnett, M. C. (in press). New N-acyl amino acid-functionalized biodegradable polyesters for pharmaceutical and biomedical applications. RSC Advances, 6(111), 109401-109405. doi:10.1039/C6RA21464A

A novel class of biodegradable polyesters has been generated by coupling poly(glycerol adipate) with N-acyl aromatic amino acids. This new set of polymers from this highly versatile polymeric platform may offer unprecedented new opportunities to prod... Read More

Indomethacin-Kollidon VA64 extrudates: a mechanistic study of pH-dependent controlled release (2016)
Journal Article
Tres, F., Treacher, K., Booth, J., Hughes, L. P., Wren, S. A., Aylott, J., & Burley, J. (2016). Indomethacin-Kollidon VA64 extrudates: a mechanistic study of pH-dependent controlled release. Molecular Pharmaceutics, 13(3), 1166–1175. doi:10.1021/acs.molpharmaceut.5b00979

Because of its weakly acidic nature (pKa of 4.5), indomethacin presents an aqueous solubility that significantly increases when changing from acidic to neutral/alkaline pH (1.5 μg/mL at pH 1.2 and 105.2 μg/mL at pH 7.4). We have therefore investigate... Read More

3D printing of five-in-one dose combination polypill with defined immediate and sustained release profiles (2015)
Journal Article
Khaled, S. A., Burley, J. C., Alexander, M. R., Yang, J., & Roberts, C. J. (in press). 3D printing of five-in-one dose combination polypill with defined immediate and sustained release profiles. Journal of Controlled Release, 217, doi:10.1016/j.jconrel.2015.09.028. ISSN 0168-3659

We have used three dimensional (3D) extrusion printing to manufacture a multi-active solid dosage form or so called polypill. This contains five compartmentalised drugs with two independently controlled and well-defined release profiles. This polypil... Read More

Monitoring the Dissolution Mechanisms of Amorphous Bicalutamide Solid Dispersions via Real-Time Raman Mapping (2015)
Journal Article
Tres, F., Aylott, J., Patient, J. D., Williams, P. M., Treacher, K., Booth, J., …Burley, J. C. (2015). Monitoring the Dissolution Mechanisms of Amorphous Bicalutamide Solid Dispersions via Real-Time Raman Mapping. Molecular Pharmaceutics, 12(5), 1512–1522. doi:10.1021/mp500829v

Real-time in situ Raman mapping has been employed to monitor, during dissolution, the crystallization transitions of amorphous bicalutamide formulated as a molecular dispersion in a copovidone VA64 matrix. The dissolution performance was also investi... Read More

Real time Raman imaging to understand dissolution performance of amorphous solid dispersions (2014)
Journal Article
Tres, F., Treacher, K., Booth, J., Hughes, L. P., Wren, S. A., Aylott, J. W., & Burley, J. C. (2014). Real time Raman imaging to understand dissolution performance of amorphous solid dispersions. Journal of Controlled Release, 188, doi:10.1016/j.jconrel.2014.05.061. ISSN 0168-3659

We have employed for the first time Raman spectroscopic imaging along with multi-variate curve resolution (MCR) analysis to investigate in real time and in-situ the dissolution mechanisms that underpin amorphous solid dispersions, with data being col... Read More

Desktop 3D printing of controlled release pharmaceutical bilayer tablets (2013)
Journal Article
Khaled, S. A., Burley, J. C., Alexander, M. R., & Roberts, C. J. (2014). Desktop 3D printing of controlled release pharmaceutical bilayer tablets. International Journal of Pharmaceutics, 461(1-2), doi:10.1016/j.ijpharm.2013.11.021. ISSN 0378-5173

Three dimensional (3D) printing was used as a novel medicine formulation technique for production of viable tablets capable of satisfying regulatory tests and matching the release of standard commercial tablets. Hydroxypropyl methylcellulose (HPMC 22... Read More

Strategies for MCR image analysis of large hyperspectral data-sets (2012)
Journal Article
Scurr, D. J., Hook, A. L., Burley, J., Williams, P. M., Anderson, D. G., Langer, R., …Alexander, M. R. (2012). Strategies for MCR image analysis of large hyperspectral data-sets. Surface and Interface Analysis, 45(1), doi:10.1002/sia.5040. ISSN 0142-2421

Polymer microarrays are a key enabling technology for high throughput materials discovery. In this study, multivariate image analysis, specifically multivariate curve resolution (MCR), is applied to the hyperspectral time of flight secondary ion mass... Read More
