Research alumni, from the Class of 2011 to the Class of 2017, returned to the Fenway to meet the current undergraduate researchers, catch up with Dr. Gerdon, and catch up with each other. This is always a great opportunity, once a year, to make new introductions and to hear about the successes and challenges of science and life. It was so great to see everyone and for so many to come back to campus. You have all made for my great years of research! Dr....

As a busy summer of experiments and hard work finally comes to an end, the entire GRAB lab team gets out of the lab to spend a day on the wonderful Charles River in Boston. Kayaking is a fun way spend some quality time bonding outside of the lab! As Bobby Tzepos begins to conclude his summer research, he looks back and realizes how much progress he’s made on the malaria biomarker experiments. After working on the electrochemical portion of the test for a year and a half now, he found a very low limit of detection! Moving along in the project, Bobby has been working on magnetic bead-antibody coupling the past few weeks and now changes gears toward the coupling of antibodies to cobalt porphyrin nanoparticles! It has been an exciting summer with great data and he can’t wait to start putting the entire plan...

A multi-year collaboration between Dr. Gerdon and the Centers for Disease Control and Prevention (CDC) in Atlanta, GA has led to a recent publication in the Journal of Chemical Education. This project involved students in the Analytical Chemistry course at Emmanuel College, but also general chemistry and analytical chemistry students at three other colleges across the country. The publication reports on “Supplemental Learning in the Laboratory: An Innovative Approach for Evaluating Knowledge and Method Transfer” and focuses on how new analytical techniques, or variations on existing techniques, could be taught to scientists across the country using online technology. Check out the abstract...

Jason Miech’18 has developed a new procedure for deconstructing microfluidic flow cells. This can allow for further analysis of the mineral via FT-IR microscopy, SEM, and AFM. These techniques will be able to more accurately access the width, height, and morphology of the formed...

During his summer research, Jake is studying how a G-quadruplex in DNA affects calcium phosphate mineralization. These mineralization experiments (like the one shown above), are prepared in 96-well plates and put in a plate reader to measure absorbance over time. He hypothesizes that the presence of a G-quadruplex should promote mineralization. However, he has been seeing strange “blips” (anomalies in the measurement) in his data which is what he is currently trying to eliminate by testing different calcium:phosphate concentrations as well as salt...

Rising senior Bobby Tzepos finally starts to finish up the optimization for the electrochemical technique to detect Co(III)-protoporphyrin IX in our early-detection malaria scheme! Next, he’s on to nanoparticle synthesis of CoPPIX, which is then going to be used to conjugate an antibody specific to the malaria protein to determine the amount of the malarial parasite in an infected person after following our proposed plan! It is much more complex than that but stay tuned throughout the summer to check-in on progress of our scheme! The picture above is the purification of Bobby’s first batch CoPPIX nanoparticles almost ready for dynamic light scattering (DLS) to measure nanoparticle...
