Students receive $5K grants to conduct research using Raman techniques

Two Appalachian State University (Boone, NC) undergraduate physics majors are working to understand collagen's structure and function, while a third is studying nanoparticles used in cancer therapy. All three are turning to Raman techniques for their work and have each received a $5,000 Undergraduate Biotechnology Research Fellowship from the North Carolina Biotechnology Center (Research Triangle Park, NC) to support research with faculty mentors in the Biophysics and Optical Sciences Facility in Appalachians Department of Physics and Astronomy.

Jessica Barrios-Hernandez (Miami Beach, FL) and Jenna Osborn (Chapel Hill, NC) will work with Dr. Jennifer Burris and Dr. Brooke Hester, both assistant professors in the department, on projects to better understand collagens structure and function. Angela Nikki Chang (Matthews, NC) will work with Hester to study nanoparticles used in cancer therapy.

Osborn will use chemical protocols and scanning electron microscopy to create and characterize collagen networks that Barrios-Hernandez will manipulate and study with Raman tweezers, a laser device that allows researchers to study and identify structure and forces for microscopic objects. Chang will use a heating laser and Raman spectroscopy to help determine the temperatures of a microscopic object to learn about nanoparticles used in cancer therapy. The nanoparticles get hot and burst tumor cell membranes. We want to measure how hot they are using a technique Angela is working on, Hester says.

Collagen is the most abundant protein in the human body. Its the main structural component in the body. Its in bone, skin, teeth and connective tissue, Burris says. Biologists understand what collagen does in the human body, but there is not yet a complete understanding of how collagen does what it does at a fundamental level.

Hester said the research can potentially help the scientific community better understand the function of collagens basic building blocks. If that was better understood, that knowledge could be used for a lot of applications, such as wound healing, creation of synthetic tissues, and to help researchers understand cervical changes that occur during pregnancy, she says.

The professors say that research fellowships, such as the ones from the North Carolina Biotechnology Center, have many benefits. These fellowships allow students to participate in research full-time and be paid for it, which is really important for a good research experience, Hester says. You cant accomplish as much when you are volunteering five to 10 hours a week, as compared to full-time work.

Burris adds, It also trains them to be better graduate students and makes them more competitive going to graduate school because of this research experience. After their fellowship, the students will be able to train new students who come into the laboratory, gaining leadership experience.

The fellowships also help move the professors research forward faster than if they did not have student assistance, Burris says. What's more, this is the third consecutive year that undergraduate physics majors at Appalachian have received these fellowships.
