Detecting Cancer Without Drawing Blood

Researchers from the Weldon School of Biomedical Engineering, the Purdue Cancer Center, and the Department of Chemistry have worked with the Mayo Clinic to develop an innovative method that can detect tumor-forming cells in blood, without the need to draw blood from the patient.  Using advanced laser imaging techniques, the process scans blood in the wrist or cheek to reveal and count circulating tumor cells, allowing a larger sample to be scanned.  Purdue UNS has the full story.

Weldon Imaging Research Featured At American Laboratory Publications

American Laboratory/American Laboratory News have made non-invasive imaging research being conducted at the Weldon School of Biomedical Engineering as the featured article in both magazines.  The article, based on a presentation by Yan Fu, Halfeng Wang, Riyi Shi, and Ji-Xen Cheng to to the ACS, examines noninvasive molecular imaging of intact myelin sheaths.  This imaging, performed using coherent anti-Stokes Raman scattering microscopy, opens new possibilities for research into and understanding of MS and other diseases that result from damage to myelin.  Myelin forms sheaths around axons, and is crucial for high-speed nerve impulse conduction.  Additional information on this research can be found in the Spotlights section of the Weldon homepage.

Gold: A Brighter Future

Gold nanoparticles and nanorods are proving to be extremely useful for biomedical applications.  Coated with special solutions, they can help quickly identify toxins, and when used with special imaging techniques, they can provide a brighter way to illuminate the inner workings of cells and molecules.  HT on the BBC story:  Instapundit.
