The Development of Ionophore-Selective Based optical chemical sensors for the determination of heavy metal ions in aqueous environments
… thin films, i.e. hybrid sol-gel thin films, PVC membranes, ORMSOLs, and functionalised cellulose membranes. The developed test strips based on 2-(5-bromo-2-2pyridydylazo)-5-diethylaminophenol (Br-PADAP) immobilised on hybrid nafion/sol-gel membranes are capable of selectively monitoring Ni2+ in …

Detection and imaging of pharmaceutical compounds in skin by MALDI-MS.
… layer in-homogeneity were experienced with nitrocellulose and polyvinyl difluoride (PVDF) membranes. Reproducible data were obtained by analysis of tissue imprints created on carbon and cellulose membranes. All subsequent work was conducted using an Applied Biosystem Qstar pulsar i hybrid …

Membranes for sustainable heat-to-electricity conversion
… and environmentally benign. In this context, cellulose membranes offer a highly sustainable, abundant and biodegradable platform with rich surface chemistry and hierarchical fibrillar architecture. The overall aim of this thesis is to establish functionalised cellulose membranes as sustainable …

Conducting Polymer Implant for On-demand Ocular Drug Delivery
… layer was polymerized on top. PEDOT-coated cellulose membranes, replicating the PEDOT sealing layer, were also fabricated and characterised for their drug permeability using Franz-cells. Finally, a prototype implant for in-vitro evaluation was fabricated by 3D printing the casing and placing …

Designing Magnetically Responsive Ultrafiltration Membranes
<p>Ultrafiltration (UF) membranes developed out of a need for protein separation processes. Currently, they are used in a variety of industries ranging from food manufacturing to pharmaceuticals for two main purposes: concentration, separation, and buffer exchange. UF membrane processes in product …

Complex photonic structures in nature: from order to disorder
Structural colours arise from the interaction of visible light with nano-structured materials. The occurrence of such structures in nature has been known for over a century, but it is only in the last few decades that the study of natural photonic structures has fully matured due to the advances in …
