My colleague Dominick Fazarro (Professor at University of Texas at Tyler) is Guest Editor of a Special Issue in the IEEE Nanotechnology Magazine. See the flyer below if interested in contributing.
Members of the Sayes Group attended and presented original research at the American Chemical Society Fall 2019 National Meeting & Expo from 25-29 August 2019. The meeting was held at the San Diego Convention Center in San Diego, CA.
Thelma Ameh (PhD Candidate) presented her research on “Evaluating the Potential of Metal Colloids for the Treatment of Pathogenic Diseases: A Case Study for Citrus Greening Disease”.
Christie Sayes (PI) presented a her talk entitled, “Accelerating nano-EHS research: Applications in nano-chemistry and nano-toxicology: An oral presentation honoring Prof. Vicki Grassian”.
Read about Christie’s recent interview with HORIBA as part of their Science in Action series.
Today for Women’s History Month, the NNI is celebrating Christie Sayes. Professor Sayes of Baylor University studies the human and environmental health effects of engineered materials. Her group specializes in characterizing the physical, chemical, and biological properties of nanoparticles in simulated intentional and unintentional exposure scenarios.
Read about all of the women celebrated by the NNI here.
On Friday, February 22, five Sayes Group members attended and presented at the annual Texas Society of Microscopy meeting held in San Antonio, Texas. Desirae Carrasco (Junior ENV major), Sahar Pradhan (1st year graduate student), Thelma Ameh (1st year graduate student), Marina Mulenos George (2nd year graduate student), and Henry Lujan (PhD candidate) participated in either the “Biology” or the “Materials” divisions. The group members received outstanding presentation awards! Thelma received Best Poster Presentation in Materials; Henry received Best Poster Presentation in Biology; and Marina received Best Platform Presentation in Materials! Congratulation to everyone for an outstanding job well done!
Dr. Vicki Liu, a post-doctoral fellow in the Texas A&M toxicology program, conducts reserach with both Professor Virender Sharma at TAMU and Professor Christie Sayes at BU. She studying the chemical interactions between metal species and chlorination processes as well as the toxicological effects of DBPs in human gut cell test systems.
Congratulations to Sayes Group member and Graduate Student, Henry Lujan, who was awarded 1st place in a micrograph contest. The contest was called, "Let Cells Glo," and was hosted by Thermo Fisher. The image taken and submitted by Henry was called “A cluster of Caco-2 cells,” which stained for the nucleus, F-Actin, and mitochondria. Winners were determined by the amount of votes each picture received. The Sayes Group is proud of Henry for his achievements and hard work.

The 66th Annual Conference for the American Society for Mass Spectrometry (ASMS) was held in San Diego, California on June 4-7, 2018 at the San Diego Convention Center. Member of the Sayes Group, Marina George, had the opportunity to attend and present at the conference. One of Marina's favorite activities at the conference was the opportunity to interact with the different stations offered in the hospitality suites. At the stations, conference attendees could engineer marshmallow towers, build molecules, and learn about the recent innovations in instrumentation.
Marina presented her poster, "Proteomic analysis of gold nanoparticle surface functionalization influence on protein corona complex formation." Marina intends to continue her research on the project and to present this project at more conferences in the future. More information about the conference can be found here
Congratulations to the 2018 Department of Environmental Science Undergraduate Research & Scholarly Achievement outstanding poster presenters! Students presented their research during URSA Scholar’s Week on March 28 & 29, 2018. From left to right, those included in the photograph are: Dr. George Cobb (Environmental Science Professor and Department Chair), Marina George Mulenos, Madison Stewart, Saskia Henery, and Dr. Christie Sayes. Winners not pictured include: Andreanna Burman, Liana DeNino, Grace Hutchinson, Julia Frandesen, Jonah Salazar, Clark Coneby, Hannah Dye, Jasmine Stovall, Dr. Susan Bratton, and Dr. Trey Brown. We are so proud of each of these hard working researchers!
The 255th American Chemical Society (ACS) National Meeting & Exposition was held in New Orleans, Louisiana on March 18-22, 2018 at the Ernest N. Morial Convention Center. Christie Sayes attended and presented data in the Special Session: Shaping Activity through Structural Modification Small Molecules to Nanoparticles. A Symposium in Honor of Professor Bing Yan. The Program can be found here (https://plan.core-apps.com/acsnola2018/customScreen/about_show).
The theme of this year’s meeting was The Nexus of Food, Energy, and Water. This topic is relevant to The Sayes Group because Dr. Sayes, Henry, and Marina are collaborating with with Professor Virender Sharma and Dr. Vicky Liu of Texas A&M University on a unique project that studies drinking water chlorination and chloramination in the water distribution system (Release of lead (Pb), formation of disinfection byproducts (DBPs), and cytotoxicity and genotoxicity of tap water).
At the ACS conference, Christie Sayes, Ph.D. presented:
“Impact of Advanced Materials on the Formation and Toxicity of Disinfection Byproducts during Drinking Water Chlorination”
