Examples of Successful Undergraduate Research Proposals

STEM Example: Investigating Stormwater as a Potential Source of Nutrients and Microplastics in the Indian River Lagoon

This project, funded through a university office, exemplifies a strong STEM research proposal. The proposal focuses on the pressing issue of microplastic pollution in the Indian River Lagoon (IRL). Microplastic research investigates plastic pollution within the size range of 5mm - 1µm, which may be composed of varying polymers and designs.

Introduction: The proposal effectively introduces the problem of microplastic pollution, highlighting the annual global plastic production and its impact on aquatic ecosystems. Annual global plastic production (393 million tons in 2016) will soon outweigh human biomass. A previous study found an average of 23.1 plastic pieces per liter of water in the IRL, as compared to a similar study on a highly industrialized Chinese estuary, which found a maximum of 13 pieces per liter. Persistent organic pollutants (POPs) readily accumulate on microplastics, which can then be released into organisms upon ingestion or deposited into the surrounding environment.

Hypothesis: The study aims to determine if stormwater outfalls are a major source of microplastic pollution in the IRL, as well as how the introduction and dispersal of microplastic pollution interacts with nutrient (nitrogen and phosphorous) availability.

Specific Aims: The proposal outlines four specific aims:

Determine if microplastics and nutrients co-occur in higher concentrations adjacent to stormwater outfalls relative to areas distant from stormwater sources.
Assess whether stormwater baffle boxes significantly reduce nutrient and/or microplastic pollution.
Investigate if terrestrial stormwater ponds serve as a sink for nutrients and microplastics prior to water discharge into the IRL.
Determine if storm events create a flush of nutrients and microplastics into the IRL.

Methodology: The study will sample 60 discrete locations in the IRL monthly for 3 months. Forty-five randomly selected sites located within the northern IRL will be tested, ranging from New Smyrna Beach to Titusville, with 15 field replicates at open stormwater outfalls, 15 at outfalls fitted with baffle boxes, and 15 controls located a minimum of 2 km from a stormwater outfall. The remaining 15 samples will be collected from randomly selected stormwater ponds within the northern IRL drainage basin. Additionally, a subsample of 5 sites of each treatment will be sampled immediately pre- and post-storm events. At each site, sampling will include the collection of two 10 cm sediment cores and two 1-L surface water samples. Each sample will be analyzed for abundance of microplastics using a dissecting microscope, identity of microplastics using Fourier-transform infrared spectroscopy (FTIR), and nutrient content including nitrate, phosphate, and ammonia.

Timeline: The project is scheduled to begin in May 2019 and last for 3 months. It includes detailed steps such as: using CEELAB-available data on GIS interface to determine 60 randomly selected stormwater drainage points for sampling; collect 2 10-cm sediment cores and 2 1-L water samples on a monthly basis from each of the 60 locations selected for microplastics examination; sediment and water samples will be filtered and analyzed under a dissecting microscope to determine microplastic abundance and diversity; Fourier-transform infrared spectroscopy will be used to identify types of plastics present; sediment and water samples at each site will be subjected to nutrient analysis including extractable nitrate, phosphate, and ammonia; complete statistical analysis of data; prepare poster presentation for UCF Summer Showcase (July 2019), SHORE Showcase for undergraduates in marine science in New Smyrna Beach (December 2019), and SURE Showcase; prepare manuscript for submission to peer-reviewed journal.

Budget: The budget includes costs for filters, reagents for nutrient extraction, travel expenses, and materials provided by CEELAB and the Aquatic Biogeochemistry Lab.

STEM Example: Selective detection of Fentanyl using electrochemical sensor based on Molecular imprinted polymer

This project aims to develop a cost effective, robust and selective electrochemical sensor based on molecularly imprinted polymers that can differentiate fentanyl and its analogues among other drugs such as heroin, cocaine and morphine.

Introduction: In recent years, the abuse and misuse of drugs has significantly increased, resulting in an annual cost of around $400 billion (French, 1997). Among them, fentanyl has progressively been used as an adulterant due to its high potency (100 and 50 times more potent than morphine and heroin, respectively). In fact, in 2015, the Drug Enforcement Agency alert fentanyl as a “threat to health and public safety” and more recently (in 2016) the Center for Disease Control and Prevention reported fentanyl and its derivatives as responsible of overdoses in ten different states in US (Scholl, 2019). Thus, the development of detection methods of fentanyl is extremely important.

Methodology: The E-MIP’s will be electropolymerized on the surface of a gold electrode (Au-E) in the presence of fentanyl and a monomer through cyclic voltammetry (CV) in an electrolytic solution at controlled pH (Beluomini, 2018). Pyrrole (PY) and ortho-phenylenediamine (o-PDA) will bethe monomers studied due to difference of their properties. A conductive and a non-conductive polymer will be formed from these monomers, polypyrrole (PPY) and poly(ortho-phenylenediamine) (Po-PDA), respectively. For the non-conductive polymer, the detection will be evaluated in two ways: (i) directly, by the electrochemical signal of the analyte; and (ii) indirectly, by the suppression of redox probe (Fe(CN)63-/4-) signal due to occupation of the MIP cavities by the analyte (Sharma,2012). For the conductive polymer, direct detection will be used because the analyte has an electrochemical signal, which will increase upon increasing the concentration (Sharma, 2012). After the polymerization, the next step is the template (fentanyl) removal from the MIP cavities by immersing the E-MIP in a solvent in which fentanyl is soluble. Finally, the E-MIP is ready to be used. The E-MIP will be characterized and evaluated by CV and square wave voltammetry. For the optimization of the E-MIP, some conditions, such as ratio of monomer to template, the number of cycles, interaction time of the monomer and template before electropolymerization, the time and solvent needed to remove and rebind the template will be analyzed. Then, the performance of the optimized E-MIP will be evaluated by the determination of the linear range, limit of detection (LOD), response time, and selectivity. The final step will be the application of the sensor to forensic and biological samples in order to improve selectivity.

Expected outcome: The expected outcome is to obtain a low cost, robust and selective sensor through the evaluation of the optimal polymer to detect fentanyl, the determination of the ideal ratio monomer:template, and the solvent for template removal from the MIP. Continuously, we expect to obtain a good linear range with low LOD and high selectivity in a short response time.
