Greetings!
 We're continuing our work to develop a sustainable Institute for biophotonics science & technology, education, and knowledge transfer, which has included discussions with our University stakeholders and the regional medical technology community. The end of January has been quite busy due to the SPIE Photonics West Conference, which was held in San Francisco, CA this year. Throughout the conference I have met with colleagues, attended our students' presentations, and hosted meetings with potential Center collaborators. Most recently this included hosting a brainstorming meeting with Biophotonics Node Leaders that will participate in our new "Biophotonics4Life Worldwide Consortium" initiative (www.biophotonicsworld.org for more information). Many thanks to all of you who paticipated in the events that took place during the month of January. We are looking forward to the activities in the coming months and are especially interested in staying abreast of the updates for "Biophotonics Week", which is scheduled to be held in Quebec City, Canada at the end of September 2010.

Cell Phone-based Microscopy and Spectroscopy
 Modern cell phones are ubiquitous devices that are equipped with many features such as a camera to record high-quality images, the capability of transmitting data, and the ability to run applications that allow performing of complex computations previously specific for much larger computing devices. Scientists from CBST ( Drs. Sebastian Wachsmann-Hogiu, Stephen Lane, and Marco Molinaro) have developed attachments for cell phones that have demonstrated the ability to record microscopic images with ~2 micrometers resolution. The premise is to develop hand-held, portable disease detection and treatment monitoring tools. For instance, they have successfully recorded images of unstained and stained pathology specimens with cellular resolution, including blood smears ( see image above - unstained blood smear). These researchers have also utilized the cell phone platform to develop a spectrometer that sorts the detected light by its wavelength components (Dr. Dennis Matthews is also affiliated with this new technology). |

Meet the Researcher - Dr. Sebastian Wachsmann-Hogiu
 Dr. Sebastian Wachsmann-Hogiu is an Associate Professor in the Department of Pathology & Laboratory Medicine at the University of California, Davis. In addition, he holds a joint appointment as the Facilities Director of the National Science Foundation Center for Biophotonics Science & Technology at the UC Davis Medical Center in Sacramento, CA. His research interests include time-resolved Raman spectroscopy/imaging, nonlinear microscopy, and SERS-based biosensors.
Dr. Wachsmann-Hogiu holds a major in Biophysics from Bucharest University in Romania. In 2000 he received his PhD in Experimental Physics from Humboldt University/Max-Born-Institute, Berlin, where he used time-resolved Raman/CARS spectroscopy to investigate elementary chemical reactions. After two-years of a postdoctoral appointment in the Chemistry Department at Carnegie-Mellon University, where he performed Stark spectroscopy on conductive polymers and biological materials, he moved to Cedars-Sinai Medical Center as a Research Scientist I.
In March 2005, he became faculty (Assistant Professor) within the Surgery Department as well as Director of the Advanced Optical Imaging Laboratory within the Minimally Invasive Surgical Technologies Institute. It was here that Dr. Wachsmann-Hogiu became interested in translating novel optical technologies into viable tools for biomedical applications.
Research projects in Dr. Wachsmann-Hogiu's laboratory include technology development and applications to the biomedical field and renewable energies:
- Time-resolved Raman/fluorescence spectroscopy and imaging
- Plasmonics and Surface Enhanced Raman Spectroscopy (SERS)
- Biosensors and assays
- Fiber-based Raman/fluorescence endoscopes
- Point of care diagnosis
- Nonlinear microscopy
- High-resolution microscopy
- Light conversion and energy storage
His research work has been supported by several agencies including NSF and NIH.

Science Mondays on KCRA Morning News
 Alisa Lee, Education Program Coordinator for the Center for Biophotonics at UC Davis, has been working with KCRA Morning News on MY58 (Comcast Cable Channel 4) to present science segments for the Sacramento Regional Science & Engineering Fair (to be held on March 26-27, 2010). These TV segments have been presented on Monday mornings starting at 7:45 AM and will be continuing through February 15th. The intention is that these segments will help students and parents tackle the preparation of student science projects taking them "step-by-step" to prepare a project board. Alisa will also be hosting a free workshop for teachers at the fair that will expand upon the Science Mondays concept.
To watch all the TV segments, please click on www.srsefair.org/science_mondays.htm. If you'd like to participate or volunteer to be a judge in the Sacramento Regional Science & Engineering Fair this March 26-27th at Rosemont High School please visit www.srsefair.org. You can also find more information on the application process as well as some of the great prizes that you could possibly win at the Fair! |

Biophotonics4Life Worldwide Consortium Node Leaders Meeting - San Francisco, Jan. 24, 2010
Thought leaders in biophotonics research from 19 nodes around the world met Sunday, January 24th, 2010, for the first Node Leaders Meeting of the Biophotonics4Life (BP4L) Worldwide Consortium. The meeting's main goal was to discuss the Consortium's mission, brainstorm about its goals, objectives and activities, review the Node Leaders' roles and responsibilities, all in order to achieve a consensus vision for the BP4L Worldwide Consortium.
BP4L Consortium's mission is to connect nodes of biophotonics scientists, clinicians, educators, organizations, companies and other enthusiasts to better harness global scientific talent and resources and focus them on fundamental discovery and important end-user needs. Drs. Dennis Matthews (USA), Brian Wilson (Canada) and Juergen Popp (Europe) co-chair the Consortium; www.biophotonicsworld.org portal is the knowledge bank for everything biophotonics that will also host social content to create and support a collaborative community.
Development of biophotonics-based standards, information dissemination about practitioners' needs (in healthcare, fundamental discovery, agriculture, and other fields), and continuous improvements of the www.biophotonicsworld.org portal were a few specific projects important to the community that are likely to be the focus of activity for the coming year. BP4L Node Leaders and other participants will host webinars and moderate Q&A sessions on www.biophotonicsworld.org; a calendar of events, funding sources, lectures and technical notes are other resources available or being developed on the portal for the biophotonics community worldwide.
Please stay tuned for further updates. |
