Towards Machine Learning In Chemical Sensing : Milk Differentiation And Quality Control Through Two-Dimensional Nano-Sensor Array, Yu Sheng Chen
Towards Machine Learning In Chemical Sensing : Milk Differentiation And Quality Control Through Two-Dimensional Nano-Sensor Array, Yu Sheng Chen
Legacy Theses & Dissertations (2009 - 2024)
Herein, we developed a novel artificial tongue using machine learning and 12 nanoassemblies (2D-NAs) to identify and analyzed different kinds of milk beverages for quality control. This biomimetic sensor array was trained to “taste” different milk types as an “artificial tongue” which is the first time we demonstrated that this sensor array can be implemented to complex systems. Two-dimensional nanoparticles (2D-nps) and nine fluorescently labeled single stranded oligonucleotides (ssDNA) with different length and nucleobases were assembled to create 12 2D-NAs. The artificial tongue was deployed to identify and analyze five milk types. All five milk types were discriminated with 95% …

Legacy Theses & Dissertations (2009 - 2024)
Nucleic acid technology along with vast variety of nanomaterials has demonstrated a great potential in many applications from biosensing studies to molecular diagnostics, from biomedical and bioanalytical research to environmental analysis. Especially short single stranded (ss) DNA molecules, called oligonucleotides, are extraordinary biopolymers featuring diverse functionality on the nanoparticles thanks to their high degree of programmability, target-specific binding or cleavage, molecular recognition ability, structure-switching capability, and unique interactions at the bio-nano interfaces. Among those, there have been many biosensing applications utilizing ss DNAs and numerous nanomaterials through various detection techniques such as fluorometric, colorimetric or electrochemical methods. Although many groundbreaking …
Comparison Of Glucose, Fructose And Sucrose Amperometric And Thermal Sensors For Detection Of Carbohydrates In Living Plant Tissue, Scott Mcadoo
Legacy Theses & Dissertations (2009 - 2024)
Ecologists currently cannot test concentrations of carbohydrates in sap in vivo. Testing carbohydrates with current technology would require destructive tissue sampling. The tissue sampling involves large amounts of time and money to collect and test. Aphids are an insect that can bypass a tree’s passive immune system and feed off a phloem region for weeks. A series of enzymatic biosensors could be used to detect the concentration changes of specific carbohydrates. A calcium chelant can be added to defeat a tree’s immune system like an aphid. The detection of three carbohydrates, fructose, glucose and sucrose are involved in this study. …
