Glycerol- and diglycerol-based polyesters: Evaluation of backbone alterations upon nano-formulation performance (2024)
Journal Article

Despite the success of polyethylene glycol-based (PEGylated) polyesters in the drug delivery and biomedical fields, concerns have arisen regarding PEG's immunogenicity and limited biodegradability. In addition, inherent limitations, including limited... Read More about Glycerol- and diglycerol-based polyesters: Evaluation of backbone alterations upon nano-formulation performance.

Synthesis of core-shell polymer particles in supercritical carbon dioxide via iterative monomer addition (2023)
Journal Article

A new, robust methodology for the synthesis of polystyrene-poly(methyl methacrylate) (PS-PMMA) core-shell particles using seeded dispersion polymerisation in supercritical carbon dioxide is reported, where the core-shell ratio can be controlled predi...

Self-assembled chitosan-sodium usnate drug delivery nanosystems: Synthesis, characterization, stability studies, in vitro cytotoxicity and in vivo biocompatibility against 143 B cells (2023)
Journal Article

Polymers are among the most studied materials as drug carriers, due to their tunable chemical structure and ability to self-assemble to give different types of nanostructures. In this study, chitosan (CS) nanoparticles (NPs) were investigated as carr...

Modification of Linear Polyethylenimine with Supercritical CO2: From Fluorescent Materials to Covalent Cross-Links (2023)
Journal Article

Along with their DNA binding ability, the secondary amines in linear polyethylenimine (L-PEI) units can also act as a reaction platform to introduce new functionalities. This renders the possibility to make a plethora of copolymers without the burden...

Predictive Molecular Design and Structure–Property Validation of Novel Terpene-Based, Sustainably Sourced Bacterial Biofilm-Resistant Materials (2023)
Journal Article

Presented in this work is the use of a molecular descriptor, termed the α parameter, to aid in the design of a series of novel, terpene-based, and sustainable polymers that were resistant to biofilm formation by the model bacterial pathogen Pseudomon...

Comparative hydrodynamic characterisation of two hydroxylated polymers based on α-pinene- or oleic acid-derived monomers for potential use as archaeological consolidants (2022)
Journal Article

The Oseberg Viking ship burial is one of the most extensive collections of Viking wooden artefacts ever excavated in Norway. In the early twentieth century, many of these artefacts were treated with alum in order to preserve them, inadvertently leadi...

N-Hydroxyethyl acrylamide as a functional eROP initiator for the preparation of nanoparticles under “greener” reaction conditions (2022)
Journal Article

N-Hydroxyethyl acrylamide was used as a functional initiator for the enzymatic ring-opening polymerisation of ϵ-caprolactone and δ-valerolactone. N-Hydroxyethyl acrylamide was found not to undergo self-reaction in the presence of Lipase B from Candid...

Sustainable ABA triblock methacrylate copolymers incorporating both high and low Tg terpene-derived monomers (2022)
Journal Article

We report the synthesis of novel terpene-based monomers: nopinyl acrylate and methacrylate, from naturally abundant β-pinene. A very high Tg value was observed for poly(nopinyl methacrylate) when synthesised by free radical polymerisation, and well-d...

A self-crosslinking monomer, α-pinene methacrylate: understanding and exploiting hydrogen abstraction (2022)
Journal Article

Crosslinking is a valuable route to creating new polymeric materials and normally involves introduction of a cross linker or some form of secondary processing. Here we report the discovery and analysis of a self-crosslinking sustainable terpene deriv...

Antimicrobial ‘inks’ for 3D printing: block copolymer-silver nanoparticle composites synthesised using supercritical CO2 (2022)
Journal Article

Silver nanoparticles (AgNP) are widely exploited for their effective antimicrobial activity against a range of pathogens. Their high efficacy in this regard has seen the global demand for AgNP in consumer products steadily increase in recent years, n...

Exploiting the tuneable density of scCO2 to improve particle size control for dispersion polymerisations in the presence of poly(dimethyl siloxane) stabilisers (2022)
Journal Article

The dispersion polymerisation of methyl methacrylate (MMA) is a widely employed method for producing discrete, spherical PMMA particles from traditional solvents, which cover a broad particle size range. With environmental impact becoming an ever mor...

Greener extraction-chemical modification-polymerization pipeline of vernolic acid from Ethiopian ironweed plant (2022)
Journal Article

Epoxidized oils are commonly used in the plastics industry as additives in the formulation of polyvinyl chloride (PVC) and as monomers in the coating industry. They are produced from petrochemical feedstocks or by chemical epoxidation of natural oils...
