The Summer Undergraduate Research Fellowship (SURF) Symposium
The development of novel and efficient mixing methods is important for optimizing the efficiency of many biological and chemical processes. Tuning the physical and performance properties of nucleic acid-based nanoparticles is one such example known to be strongly affected by mixing efficiency. The characteristics of DNA nanoparticles (such as size, polydispersity, ζ-potential, and gel shift) are important to ensure their therapeutic potency, and new methods to optimize these characteristics are of significant importance to achieve the highest efficacy. In the present study, a simple segmented flow microfluidics system has been developed to augment mixing of pDNA/bPEI nanoparticles. This DNA and …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Lyophilization is a common method used to preserve pharmaceutical and biological products. Accurately measuring temperature during the three stages of lyophilization: freezing, primary drying, and secondary drying, is important to ensure product consistency and to reduce operating costs. Wireless temperature sensors were evaluated to determine if temperature is monitored accurately and to determine if wireless temperature sensors offer advantages over traditional temperature measurement technologies. These sensors contain three capacitors to monitor temperature as the solvent is sublimated. A Millrock Technology REVO lyophilizer was used for testing. Water and 5% w/v sucrose solution were distributed in 3 mL fill volume increments …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Production and isolation of proteins are difficult, costly and time-consuming processes. The aim of this project is for the development of plasmids, which allow for streamlined production and isolation of proteins. To allow for modular insertion of varying segments of DNA we are using ‘recursive directional ligation by plasmid reconstruction’. This technique uses type II restriction endonucleases, which cut downstream from their recognition site allowing multiple insertions without losing a restriction site. Using this process, we can ligate multiple DNA sequences together and express them to be able to construct a scar less fusion protein. In order to accomplish this, …
