Abstract:

The thesis describes a programme of work to develop a novel cellulose based fibre. The most important innovative step in this work lies in the manufacture of the fibre from a chiral nematic suspension of plant based cellulose nano-fibrils. In the course of the project a number of key steps have been addressed in the development process. These included: • Developing a method for extraction of nano-fibrils from wood and cotton based pulp and filter paper; • Development of concentrated chiral nematic suspensions of the nano-fibrils suitable for extrusion (spinning); • Spinning a continuous fibre

Abstract:

Amyloid fibrils are a type of protein nanofibres that form when a normally soluble protein aggregates in a regular fashion via self-association. Their organised and repetitive β-sheet structure is thought to be a generic property of all proteins, depending on the environmental conditions. The nanometre size and high stability of these protein nanofibres are attractive features to exploit in bionanomaterials. This thesis aimed to manipulate insulin amyloid fibrils, as a model protein nanofibre system, through investigating the effect of chemical modification on insulin fibril formation in het

Abstract:

Amyloid assemblies consist of an organised cross ~-sheet structure and can be formed by many proteins or peptides regardless of peptide sequence. Amyloid has been utilised by many species for a variety of functions, however, inappropriate amyloid formation is associated with a spectrum of devastating amyloid diseases. The nature of the primary cytotoxic species in amyloid disease is widely debated, with the consensus favouring pre-fibrillar, oligomeric entities over mature end-stage fibrils, despite an increasing body of evidence that suggest at least some fibrils may be associated with cytoto

Self-assembly of biomolecules into beta-sheet structures can be applied in the creation of nano-materials with novel electrical, optical, catalytical, or/and mechanical characteristics.

Such nanostructures can be used to produce nanoscale functional systems. Herein, different mutant and hybrid proteins, which were able to form fibrillar structures, were constructed and the properties of fibrils were investigated. Designed cy

The conversion of PrPC, the normal form of the prion protein, to PrPSc, the protease-resistant disease specific form, is central to the pathogenesis of the transmissible spongiform encephalopathies. The mechanism underlying this conformational change remains elusive but the demonstration that PrPSc can infer protease-resistance to PrPc in-vitro in the presence of guanidine hydrochloride using a cell-free system offers a useful approach to investigating this process. The limitations of such systems however are that significant efficiencies of conversion are only observed in the presence of an e

Abstract:

In this thesis, a protein is designed incorporating an electron transport protein that self-assembles into amyloid fibrils in order to investigate the possibility of producing self-assembling bio-electronic conductors. These fibrils are found to display the electron transport protein and as a consequence, exchange electrons with their surroundings. The effects of non beta-sheet core regions on the properties of amyloid fibrils have been studied. In particular it is shown that non-core regions have sufficient flexibility to average their local magnetic environments to yield sharp resonances whe

Amyloid fibrils are a misfolded state formed by many proteins when subjected to denaturing conditions. Their constituent amino acids make them an excellent target for enzyme immobilisation and their strength, stability and nanometre size are attractive features for exploitation in the creation of new bionanomaterials. The aim of this thesis was to functionalise amyloid fibrils by conjugation to glucose oxidase (GOD).

The current landscape of nanotechnology has focussed attention on materials that self-assemble. The search for such materials has unsurprisingly led to the biological world, where functional nanoscale biomolecular assemblies are in abundance. Amyloid fibrils are one such self-assembling biological structure, formed when native proteins misfold into insoluble fibrous quaternary structures. This research has explored the use of amyloid fibrils formed from waste proteins, namely crude crystallin proteins from fish eye lenses, as biological nanowires.

There is a fundamental need for techniques that are capable of determining the mechanical properties of biological fibrils at the nanoscale. This is because of the direct relationship between structure and function of an organism and the mechanical properties of its building blocks.

Although collagen has been investigated intensively in the last decades, relatively little is known about its mechanics and inner structure. In this

The amyloidoses are a group of debilitating disorders which include neurodegenerative diseases such as Alzheimer’s disease and systemic diseases such as dialysis-related amyloidosis (DRA).

Amyloid fibrils are formed by a variety of proteins and peptides despite differences in sequence and native structure. Amyloid formation occurs by a nucleated growth mechanism and proceeds via oligomeric intermediates into mature fibrils. Despite intense research, the molecular mechanis

Abstract:

Amyloid fibrils are an insoluble, highly ordered, fibrous protein structure, which have increasingly been recognised as having bionanotechnology applications. Their ability to selfassemble allows a bottom-up approach to material design. Their nanometre dimensions affords them a high surface-to-volume ratio and their proteinaceous building blocks from which they are assembled allow for decoration with biomolecules and chemicals through amino acid residues. Amyloid fibrils are therefore a potential nanoscaffold for immobilisation of biomolecules. Immobilisation offers a solution to the problems

In this study, we show that PMEL amyloid fibrils, secreted by cancer cells, are component of the extracellular matrix and modify its stiffness thus activating mechanosignalling. We highlight

Alzheimer’s Disease (AD) is the leading cause of dementia in the world and the World Health Organization has recognized AD as a global public health priority. One of the pathological hallmarks of AD is amyloid plaques formed from amyloid β (Aβ) fibrils. Aβ is formed when amyloid precursor protein is cleaved by secretase enzymes. Cleavage by different secretases causes Aβ to occur in different forms, mainly as 40 and 42 residue long proteins, called Aβ1-40 and Aβ1-42, where Aβ1-42 is more likely to form amyloid fibrils and is therefore considered more harmful.
