Multiboronic acid-conjugated chitosan scaffolds with glucose selectivity to insulin release (2017)
Journal Article
Siddiqui, N. A., Billa, N., & Roberts, C. J. (in press). Multiboronic acid-conjugated chitosan scaffolds with glucose selectivity to insulin release. Journal of Biomaterials Science, Polymer Edition, 28(8), https://doi.org/10.1080/09205063.2017.1301774

The principal challenge for the use of boronic acids (BA) as glucose sensors is their lack of specificity for glucose. We examined the selectivity of and insulin release from two boronic acids- (2-formyl-3-thienylboronic acid (FTBA) and 4-formylpheny...

Correlating gastric emptying of amphotericin B and paracetamol solid lipid nanoparticles with changes in particle surface chemistry (2016)
Journal Article
Amekyeh, H., Billa, N., & Roberts, C. J. (2017). Correlating gastric emptying of amphotericin B and paracetamol solid lipid nanoparticles with changes in particle surface chemistry. International Journal of Pharmaceutics, 517(1-2), https://doi.org/10.1016/j.ijpharm.2016.12.001

Oral delivery of pharmaceuticals requires that they retain their physical and chemical attributes during transit within the gastrointestinal (GI) tract, for the manifestation of desired therapeutic profiles. Solid lipid nanoparticles (SLNs) are used... Read More about Correlating gastric emptying of amphotericin B and paracetamol solid lipid nanoparticles with changes in particle surface chemistry.

Mucoadhesive chitosan-pectinate nanoparticles for the delivery of curcumin to the colon (2016)

Controlling the physical dimensions of peptide nanotubes by supramolecular polymer coassembly (2016)
Journal Article
Adler-Abramovich, L., Marco, P., Arnon, Z. A., Creasey, R. C., Michaels, T. C., Levin, A., …Gazit, E. (2016). Controlling the physical dimensions of peptide nanotubes by supramolecular polymer coassembly. ACS Nano, 10(8), 7436-7442. https://doi.org/10.1021/acsnano.6b01587

Molecular self-assembly of peptides into ordered nanotubes is highly important for various technological applications. Very short peptide building blocks, as short as dipeptides, can form assemblies with unique mechanical, optical, piezoelectric, and...

Electrospray deposition in vacuum as method to create functionally active protein immobilization on polymeric substrates (2015)
Journal Article
Fornari, E., Roberts, C. J., Temperton, R. H., & O’Shea, J. N. (2015). Electrospray deposition in vacuum as method to create functionally active protein immobilization on polymeric substrates. Journal of Colloid and Interface Science, 453, 252-259. https://doi.org/10.1016/j.jcis.2015.05.007

We demonstrate in this work the deposition of a large biological molecule (fibronectin) on polymeric substrates in a high vacuum environment using an electrospray deposition system. Fibronectin was deposited and its distribution and structure investi...

Characterisation of human saliva as a platform for oral dissolution medium development (2015)
Journal Article
Gittings, S., Turnbull, N., Henry, B., Roberts, C. J., & Gershkovich, P. (2015). Characterisation of human saliva as a platform for oral dissolution medium development. European Journal of Pharmaceutics and Biopharmaceutics, 91, 16-24. https://doi.org/10.1016/j.ejpb.2015.01.007

Human saliva is a biological fluid of great importance in the field of dissolution testing. However, until now, no consensus has been reached on its key characteristics relevant to dissolution testing. As a result, it is difficult to select or develo...
