Lindsey is a physics major who has worked with Dr. Nina Abramzon, and was a CAMPARE student.

Participating in undergraduate research at Cal Poly has been an amazing experience. During the summer of 2012 I was able to participate in the CAMPARE program and over the past two years I have had the opportunity to work with Dr. Nina Abramzon on several projects involving optical emission spectroscopy and plasma technology. This past year we collaborated with Dr. Steve Alas and biology graduate student Selma Reyes in developing new methods for preventing bacteria growth on internal prosthetics using atmospheric pressure plasma. We investigated the effectiveness of plasma treatment for preventing the growth of biofilms from Staphylococcus Epidermidis and Pseudomonas Aeruginosa bacteria on several implant materials including stainless steel, pure commercial titanium, and titanium boron alloys. We treated several metal coupons of each type using radio frequency atmospheric helium-oxygen plasma. We then allowed for the P. Aeruginosa bacteria to grow on metals that we treated with plasma and metals that were left untreated. The results showed a significant drop in the amount of bacteria on plasma treated titanium boron alloys compared to non-treated titanium boron alloys. The stainless steel and pure titanium showed more bacteria on the treated metals. The next step is to repeat the experiment with the S. Epidermidis bacteria and a higher powered plasma reactor.  I have really enjoyed working with Dr. Abramzon and sharing this experience with my lab mates and friends Ashley Matsushita, Tanner Worden and Ryan Hernandez.
