Highlights

CAMD Targets Cancer
Professor Ken Hogstrom and his associates Marie Varnes, Kip Matthews, and Erno Sajo of the Medical Physics Group Department of Physics and Astronomy and Mary Bird Perkins Cancer Center are searching for drugs that will allow radiation dose to preferentially target the cancerous cells. Research to date has focused on a well known radiosensitizing drug called iododeoxyuridine (IUdR).


Functionalizing Nanotubes for Biomedical Applications
In this project, Dr. Donhui Zhang, LSU Department of Chemistry, and her team of researchers investigate the orientational control of CNT through their self-assembly with lyotropic liquid crystals of a biocompatible polypeptide (i.e., PBLG).


Resisting Resistance: Developing New Drugs to Combat Antibiotic Resistant Bacteria
Dr. Grover Waldrop, LSU Department of Biological Sciences, is developing a molecule to inhibit the enzyme acetyl-CoA carboxylase and kill bacteria that will serve as a lead for developing antibiotics.


Environmental Toxicology: Nanoparticles and pollutant formation in combustion processes
Using x-rays at CAMD, Professors Barry Dellinger, Erwin Poliakoff, and Robin McCarley from the LSU Chemistry Department are studying the chemical reactions that occur on metal oxide surfaces. The goal of this research is to determine what is happening at the microscopic level in order to reduce pollutant formation in real-world processes.


What Triggers Asthma and Inflammatory Response?
Professor Marcia Newcomer, a protein crystallographer and chair of the LSU Department of Biological Sciences, uses protein crystallography to determine molecular structures with x-ray diffraction.


Alternative Fuels from Biomass
Kerry Dooley, S. Adusumilli, V. Kalakota, LSU Chemical Engineering determine the intermediate compounds that form using X-ray Diffraction at CAMD.


Microbial Populations in CAVES: A Comparison of Sulfur Biosignatures
Annette Summers Engel, LSU Assistant Professor of Geomicrobiology, uses X-ray Absorption Near Edge Structure (XANES) spectroscopy in her study on microbial populations.


LSU Biological Science Professor is Resisting Resistance.
Dr. Waref Azmeh, an infectious disease specialist in Baton Rouge, discusses the origin and the dangers of bacterial resistance to antibiotics, and Dr. Grover Waldrop, Associate Professor of Biological Sciences at LSU, describes how he and his lab are designing ways to overcome this desperate situation.  Dr. Waldrop discusses the importance of the CAMD X-ray-crystallography research station in his research.


Disabling a Killer Virus
Dr. Andrew Russo, University of Texas Medical Branch at Galveston, used the protein crystallography beamline at CAMD to study the structure of a protein called nsp2 protease in the Venezuelan Equine Encephalitis virus. He will use this knowledge to develop an inhibitor that will prevent the virus from replicating and killing countless humans and farm animals.

Sifting Slush
Hurricane Katrina (2005) left an abundance of tragic waste in its wake: broken lives and mangled city artifacts that only a city as old as New Orleans can generate. In an attempt to investigate what else it left behind in New Orleans, CAMD-LSU researchers, Amitava Roy and John Pardue, along with their respective research teams, use X-ray Absorption Spectroscopy to study the speciation of heavy metals and their sources in the flood sediments.


Reducing Dimensions: Wiry Metals and Skinny Oxides
One-dimensional nanomaterials are fertile building blocks for manufacturing devices in nanoelectronics and photonics. CAMD-LSU researchers, Orhan Kizilkaya, Richard Kurtz, Yaroslav Losovyj, Phil Sprunger, and Wei Chang Zhao, in two separate studies, explore exciting possibilities with silver nanowires and ultra-thin oxides, using angle-resolved photoemission spectroscopy and scanning tunneling microscopy.

Detecting Cancer
LSUís CAMD and the Pennington Biomedical Research Center, in a collaborative effort led by Challa Kumar and Carola Leuschner, are developing unique nanoparticles designed to detect cancer cells efficiently. Read more to find out about nanoscience at CAMD.
