School of Engineering Department of Chemical and Biological Engineering 70 Design and Development of Functional Food Supervisor: Marshal LIU / CBE Student: WONG Wang Chi / BIEN Course: UROP 1000, Summer The goal of the experiment is to find out the best leftover for the brewing of mead from the researcher fridge and cabinet. In this study, the researcher examines the capability of unopened raisins, blueberries and tea as main ingredients. The mead antioxidants and probiotic properties are examined by using the UV spectrometer, microscope and agar plate. The antioxidants concentration is then quantified at 220nm, 250nm, 260nm, 280nm and 290 nm after dilution. While the microscope is used to confirm the contents of the probiotic content, and the plate is for calculating the concentration of the probiotic contents. Optimization of Illumination and Nutrients for Hydroponics System Supervisor: Marshal LIU / CBE Student: WU Evan Tyler / CENG Course: UROP 1000, Summer With soil-based agriculture being challenged in the face of the climate crisis, hydroponics is becoming an increasingly popular alternative to agriculture due to its efficiency in water usage and space. This report will explore the fundamentals of hydroponics and focus on investigating the effects of different colors of light (red, blue, and white) on plant growth. Mung beans were grown in vertical farms with hydroponic sponges as a growing medium over 2 weeks. The tallest mung bean plant was 4.2cm under red light, while the shortest plant was 3.6cm under blue light. The results suggest that increasing concentrations of red light may be the most optimal color in growing plants in a hydroponic system, however additional sampling and time would be required to confidently affirm this suggestion. Non-invasive Health Assessment via an Oral Care Device Supervisor: NYEIN Hnin Yin Yin / CBE Student: CHANDWANEY Saloni Vimal / BIEN Course: UROP 1000, Summer This progress report outlines the development of an antibody-based detection device for measuring biomarkers in gingival crevicular fluid (GCF), obtained from the crevices surrounding teeth. The specific biomarker of interest is interleukin-1 beta (IL-1β), a proinflammatory cytokine present in heightened amounts in GCF as a result of periodontal disease, which is the most common cause of tooth loss worldwide. We explore both a paper-based and a thread-based analytical device, with the thread-based approach proving to be more viable. Though the research is recent, further experimentation could oversee its progression into an accurate point-of-care device for use in investigating the presence and severity of periodontal disease.
