To determine the level of Escherichia coli (E. coli) contamination, after induction with 150 µL of breast milk, the B-Per bacterial protein extraction kit was added to a solution containing an alginate-based microcapsule assay. Within this 3 mm spherical novel sensor design, X-Gal (5-Bromo-4-Chloro-3-Indolyl β-_D-Galactopyranoside) was entrapped at a concentration of 2 …

Role Of Nanoparticle–Polymer Interactions On The Development Of Double-Network Hydrogel Nanocomposites With High Mechanical Strength, Andrew Chang, Nasim Babhadiashar, Emma Barrett-Catton, Prashanth Asuri

Bioengineering

Extensive experimental and theoretical research over the past several decades has pursued strategies to develop hydrogels with high mechanical strength. Our study investigated the effect of combining two approaches, addition of nanoparticles and crosslinking two different polymers (to create double-network hydrogels), on the mechanical properties of hydrogels. Our experimental analyses revealed that these orthogonal approaches may be combined to synthesize hydrogel composites with enhanced mechanical properties. However, the enhancement in double network hydrogel elastic modulus due to incorporation of nanoparticles is limited by the ability of the nanoparticles to strongly interact with the polymers in the network. Moreover, double-network hydrogel …

Electromechanics Modelling Of The Effects Of Myocardial Infarction On Left Ventricular Remodelling, Chin Neng Leong

Student Works (2020-2029)

Myocardial infarction (MI) is one of the diseases with the highest mortality rate. Following MI, myocardium experiences abrupt changes in its loading condition due to the presence of infarct. In response to such changes, myocytes undergo adaptations to maintain homeostasis. However, maladaptation can happen and lead to remodelling, in which the left ventricle (LV) gradually loses its function and eventually turns into heart failure. Nevertheless, the mechanisms underlying LV remodelling are still poorly understood. In this study, a generic LV model was developed, incorporating realistic fibre orientation and excitable contracting myocardium. It was demonstrated that the developed model is capable …

Low-Cost Solid State Nanopore Biosensing Technology Towards Early Disease Detection, Julian Bello

Theses and Dissertations

Solid-state nanopore based biosensors are cost effective, high-throughput engines for single molecule detection of biomolecules, which is useful for detecting epigenetic modifications on DNA; one of these being the potentially cancerous hypo, or hypermethylation of CpG islands. Despite its immense potential in the realm of disease diagnostics, nanopore detection as it stands faces various limitations that inhibit it from widespread commercial use. These include the complex method of solid-state nanopore fabrication, fast DNA translocations through the pore causing poor resolution, and poor signal to noise ratio. The following work aims to improve the efficacy of the solid-state nanopore biosensing platform …

Journal of Appalachian Health

A meta-analysis of oncology papers from around the world revealed that cancer patients who lived more than 50 miles away from hospital centers routinely presented with more advanced stages of disease at diagnosis, exhibited lower adherence to prescribed treatments, presented with poorer diagnoses, and reported a lower quality of life than patients who lived nearer to care facilities. Connected health approaches—or the use of broadband and telecommunications technologies to evaluate, diagnose, and monitor patients beyond the clinic—are becoming an indispensable tool in medicine to overcome the obstacle of distance.
