Jake spends a lot of time pipetting in the research lab when preparing his plate reader mineralization experiments. In his Analytical Chemistry lab last week, he was put to the test to truly see how well he can pipette when he was tasked with calibrating his own 1000µL pipette. He found that the pipette calibrated to within less than 2µL and with a very low standard deviation! Jake will continue to use his pipetting skills while preparing his mineralization solutions for G-quadruplex analysis in the research...

It’s not often that Dr. Gerdon gets to head into the lab to work on a new experiment, but the introduction of a new LC-MS instrument in the department was the right catalyst! Dr. Gerdon is hoping to using this instrument in the Analytical Chemistry class at the end of the Spring 2018 semester to help students study and quantify FDC dyes (Blue 1, Yellow 5, and maybe others) in a mixture. It’s a fun project and a great opportunity to work with a new instrument. Maybe there will be applications for studying DNA and calcium binding down the road as...

Dr. Gerdon is teaching the CHEM 1103 class this fall semester. This is an accelerated course that covers two semesters of general chemistry in just one term. Freshmen in this course have a strong background in chemistry and math coming into Emmanuel College and excel in this setting. In lab, these students get to learn more advanced techniques, including gold nanoparticle synthesis and analysis of mineralization. These students synthesized glutathione protected monolayer protected clusters (MPCs) and will test them as templates in calcium phosphate mineralization. This will help the research team understand the influence of nanoparticles on mineral formation. Thanks to the CHEM 1103...

Senior Krista Meserve is all smiles in this selfie with the ICP-AES! This instrument utilizes atomic emission spectroscopy to measure the intensity of emission at a wavelength specific to the element of interest. Using a calibration curve, the intensity can be correlated to a concentration of the element, which is more useful to our work. Krista is using this instrument to calculate the difference in concentration of calcium in the presence and absence of DNA, hoping to understand how many individual calcium ions bind to a DNA strand. She is also smiling because she was awarded a travel grant from the New England Section of the American Chemical Society (NESACS) to travel to the ACS national meeting in New Orleans, LA this...

After several weeks of synthesis, Alex finished the first batch of gold nanoparticle monolayer protected clusters (MPCs) using tiopronin, an amino acid derivative, as the protecting ligand. The gold MPCs will be tested with different concentrations of calcium and phosphate to test their effect on mineralization. Other molecules such as DNA and polyethylene glycol will be attached to the gold MPCs down the road to compare to the tiopronin gold...

Senior Jason Miech took a break from research and school work to run his first half-marathon! He finished the BAA half-marathon with a time of 1 hour 47 minutes 22 seconds. Although running experiments and doing homework is important, it is equally as important to set aside some time for...
