A Rapid And Ultra-Sensitive Biosensing Platform Based On Tunable Dielectrophoresis For Robust Poc Applications, Yu Jiang
Doctoral Dissertations
With the ongoing pandemic, there have been increasing concerns recently regarding major public health issues such as abuse of organophosphorus compounds, pathogenic bacterial infections, and biosecurity in agricultural production. Biosensors have long been considered a kernel technology for next-generation diagnostic solutions to improve food safety and public health. Significant amounts of effort have been devoted to inventing novel sensing mechanisms, modifying their designs, improving their performance, and extending their application scopes. However, the reliability and selectivity of most biosensors still have much to be desired, which holds back the development and commercialization of biosensors, especially for on-site and point-of-care (POC) …
Optimization Of E-Textiles For Lactic Acid Detection, Andrew Laboy, Mallory David
Optimization Of E-Textiles For Lactic Acid Detection, Andrew Laboy, Mallory David
Williams Honors College, Honors Research Projects
The overall goal of the project is to develop an e-textile that will be able to determine different characteristics of an athlete's health through multiple sensors. The goal of these sensors is to monitor physiological parameters for health and fitness uses in real time. Building from the existing sodium concentration sensor, these new sensors will detect lactate levels within sweat to monitor instantaneous health which allows customization of workout and overall health regimen.
Applications Of Cellular Components In Engineered Environments, Xiao Hu
Applications Of Cellular Components In Engineered Environments, Xiao Hu
Graduate Theses, Dissertations, and Problem Reports
Manipulation of cellular components in synthetic environment has attracted interest for applications ranging from sensors to nanelectronics and from catalysis to biomedical devices. In such applications, biological-based processes such as specific recognition and self-assembly direct the formation of hierarchical structures, all at minimum energetic costs, with high efficiency and reliability.
Among such cellular machines, microtubules and kinesins have attracted special interest. Inside the cells, microtubules are giving structural integrity while serving as regular and uniform tracks for transport of vesicles or organelles. Kinesin uses a microtubule track in vivo to progress to specific locations with processive and coordinated steps, all …
Fabrication Of Flexible, Biofunctional Architectures From Silk Proteins, Ramendra K. Pal
Fabrication Of Flexible, Biofunctional Architectures From Silk Proteins, Ramendra K. Pal
Theses and Dissertations
Advances in the biomedical field require functional materials and processes that can lead to devices that are biocompatible, and biodegradable while maintaining high performance and mechanical conformability. In this context, a current shift in focus is towards natural polymers as not only the structural but also functional components of such devices. This poses material-specific functionalization and fabrication related questions in the design and fabrication of such systems. Silk protein biopolymers from the silkworm show tremendous promise in this regard due to intrinsic properties: mechanical performance, optical transparency, biocompatibility, biodegradability, processability, and the ability to entrap and stabilize biomolecules. The unique …
Label-Free And Aptamer-Based Surface Enhanced Raman Spectroscopy For Detection Of Food Contaminants, Shintaro Pang
Label-Free And Aptamer-Based Surface Enhanced Raman Spectroscopy For Detection Of Food Contaminants, Shintaro Pang
Doctoral Dissertations
The development of analytical methods to detect food contaminants is a critical step for improving food safety. Surface enhanced Raman spectroscopy (SERS) is an emerging detection technology that has the potential to rapidly, accurately and sensitively detect a wide variety of food contaminants. However, SERS detection becomes a challenge in real complex matrix, such as food, since non-specific matrix signals have the potential to drown out target associated Raman peaks. In this dissertation, we focused on the development and application of label-free, aptamer-based SERS in order to improve the accuracy and specificity of target contaminant detection in food. To accomplish …
Development Of A Simple Handheld Biosensor For Waterborne Pathogens, Bryce C. Jones
Development Of A Simple Handheld Biosensor For Waterborne Pathogens, Bryce C. Jones
Chemical Engineering Undergraduate Honors Theses
Current methods of detecting waterborne pathogens involve testing strips which take 24-48 hours to yield results, or require expensive equipment in order to function. In minimalist environments, these two technologies are not always applicable to test water quality. With the emergence of a new method of PCR, named LAMP PCR, it is possible to quickly and accurately detect pathogen DNA in a water sample. In order to scale this technique into a simple device, the aspects of the reaction must be accommodated, and a visual detection method chosen. A handheld device which keeps the isothermal LAMP PCR stable for the …
