1. Jahanshahi-Anbuhi, Sana. Development of Ready-to-Use Biosensors for Diagnostics and Biosensing.

Degree: DEng, 2014, McMaster University

Ideally, every person in the world should have access to a safe and clean water supply; if not all sources of water are clean and safe, at the very least, an effective method to detect water contamination should be readily available. An effective detection method should not only be sensitive, rapid, robust, and affordable, but, ideally, it should also be equipment-free and easy to transport and deliver to the end-users. The main goal of this project is to develop a variety of bits and pieces of bioassay systems, with a particular focus on paper-based bioactive devices in order to provide portable and ready-to-use biosensors which can be useable by anyone anywhere around the world without requiring formal training. According to the World Health Organization (WHO), 76,000 people each year die in India alone because of pesticide poisoning. Long term exposure to organophosphate pesticides is known to have adverse effects on neurological function and can lead to Alzheimer's Disease, Attention Deficit Hyperactivity Disorder (ADHD), and reduced Intelligence Quotient (IQ). The likelihood of long term exposure to pesticides is heightened in developing countries, so a reliable and inexpensive pesticide sensor is a much-needed device in the developing world. To address this need, this project reports on the development of a fully-automated bioactive paper-based sensor for the detection of organophosphate pesticides. In the proposed biosensor, two innovations were implemented to achieve a full-automated format for the pesticide sensor: (I) First is a PUMP ON A PAPER (Jahanshahi-Anbuhi et al., LOC, 2012) that increases the flow rate of fluids within paper-based microfluidic analytical devices and sequentially brings two separate liquid streams to the enzyme test zone on the paper sensor, and (II) the second innovation is a PIPETTE ON A PAPER (Jahanshahi-Anbuhi et al., LOC, 2014) that involved the creation of a pullulan (a natural non-ionic polysaccharide) temporary bridge-system to transfer a known amount of solution to the sensing zone that, gives the enzyme zone a chance to dry and accept the substrate solution from the slow channel after a fixed period of time. This proposed format results in a simplified assay that detects the presence of pesticides automatically without any further manipulation from the user. However, the shelf life of this assay kit is challenging due to instability of both enzyme (AChE) and substrate (IDA) at room temperature. AChE loses its enzymatic activity when stored at room temperature and IDA becomes oxidized quickly. This problem is not unique to these two bio reagents, however; almost all bioassays which use bio-reagents (such as enzymes and small-molecular substrates) are unstable to varying degrees and require special shipping and storage. The instability of these molecules can arise from either thermal denaturation or chemical modification, such as oxidation or hydrolysis. Because of these issues, they often have to be shipped on dry ice with special packaging, which is costly.

2. Ketep, Françoise. Piles à combustible microbiennes pour la production d'électricité couplée au traitement des eaux de l'industrie papetière : Microbial Fuel Cell for electricity production and water treatment of paper industry.

Degree: Docteur es, Génie civil, 2012, Université de Grenoble

L’objectif de la thèse est d’évaluer la faisabilité de la technologie de pile à combustible microbienne pour la production d’électricité couplée au traitement d’effluents de l’industrie papetière. La première partie du travail montre que de nombreux effluents papetiers permettent de former des biofilms anodiques efficaces. Lorsque les effluents sont complémentés en acétate et l’anode polarisée à -0,3V/ECS des densités de courant de 12 A/m² et des rendements faradiques de 90% ont été obtenus. Lorsque les effluents sont utilisés comme seuls substrats, les densités de courant atteignent 6 A/m² et les rendements faradiques 30%, avec des abattements de DCO jusqu’à 50%. Les biofilms anodiques optimaux ont été associées à des cathodes à air abiotiques pour concevoir des piles complètes. Des puissances surfaciques de 294 mW/m² à 596 mW/m² ont été obtenues avec deux effluents différents.

The objective of this thesis was to assess the feasibility of the microbial fuel cell technology for the production of electrical energy coupled with the treatment of pulp and paper effluents. The first part of work showed that various pulp and paper effluents are suitable to form efficient anodic biofilms. When the effluent was supplemented with acetate and the anode polarized between at -0.3 V/SCE, current densities of 12 A/m² and Coulombic efficiencies up to 90% were obtained. When effluents were provided as the sole substrate, current densities reached 6 A/m² and Coulombic efficiencies 30%, with COD removal around 50%. The optimal anodic biofilms were associated with associated with abiotic air cathodes to design complete microbial fuel cells. Power densities from 294 mW/m² to 596 mW/m² were obtained with two different effluents.
