For over a decade Professor Geddes and the IoF have described in over 200 peer-reviewed manuscripts and greater than 100 patents, the interactions of Fluorophores (fluorescent molecules / dyes) with Plasmon supporting materials. This area of science, which was originally termed “Metal-Enhanced Fluorescence (MEF)” by Professor Geddes in 2001, has become a very active area of research in the world today, not only academically but also commercially and militarily, with the IoFs work cited » 5000 times today in the peer reviewed literature. To celebrate this very active area of research and the IoFs pioneering work in this field, Professor Geddes and the IoF have organized and published a special themed issue in PCCP (Physical Chemistry Chemical Physics) dedicated to Metal-Enhanced Fluorescence (MEF).An Image from one aspect of the groups MEF work is featured on the front cover of PCCP.
Congratulations to Professor Geddes and the IoF for their continued successes in MEF.

Applicants are expected to establish a vigorous, externally funded, research program in any sub-discipline of an area broadly defined as analytical chemistry (e.g., bio-analytical, materials, energy, etc.). The successful applicant should have a PhD and postdoctoral experience and will be expected to teach at both the undergraduate and graduate (PhD and MS) levels, with particular emphasis on analytical and instrumental chemistry courses. Applications from women, minorities, individuals with disabilities and other traditionally under-represented groups in the sciences are especially encouraged. The appointment will commence August 2014. The Department (www.umbc.edu/chem) is a highly cross-disciplinary and interactive group of faculty, post-doctoral fellows, and students engaged in cutting edge research, working in state-of-the-art laboratory facilities in a recently renovated building. UMBC is strategically situated on a suburban campus in the intellectually and culturally vibrant Baltimore-Washington corridor, providing unique opportunities afforded by its diversity, intermediate size and world-class infrastructure. Applicants should submit curriculum vitae, description of research plans, and statement of teaching philosophy as well as arrange for three letters of recommendation to be sent to:

Professor Chris D. Geddes and the Institute of Fluorescence have recently been announced winners of the 2013 innovator of the year award by the Daily Record. Dr Geddes and the IoF have won the award for their development of a very rapid and low cost test for the determination of Sexually Transmitted Infections (STIs). Typically clinical diagnostics for STIs can take as long as 48 hrs, over which time the epidemiological transmission and infection spread can occur further. The IoFs technology can detect the presence of an STI within 8 minutes, allowing a real-time point-of-care test to be realized, meaning that patients presenting with STI-like symptoms in an emergency department / clinic can be diagnosed and potentially treated on-site. The new test costs less than $2 per swab, making the test attractive for downstream commercialization and clinical use.
In addition to Dr Geddes, IoF / Chemistry Graduate Student Johan Melendez has worked on the project as part of his thesis, the clinical validation of the technology recently being reported in the Journal of Clinical Microbiology.
Further details of the award and other technology developments can be found on the IoF (UMBC’s Institute of Fluorescence) website.
We congratulate Professor Geddes and the IoF team on this notable award.

The Ruth Kirschstein Diversity in Science Award was established to honor an outstanding scientist who has shown a strong commitment to the encouragement of under-represented minorities to enter the scientific enterprise and/or to the effective mentorship of those within it. The award will consist of a plaque, a cash prize of $3,000, and travel expenses to present a lecture at the annual ASBMB meeting. The recipient will be chosen by the Minority Affairs Committee. Nominations must be originated by Society members however, the nominee need not be an ASBMB member. posted Jul 01,2013
Dr Marie Christine Daniel Onuta was awarded a UMB-UMBC Research and Innovation Partnership Seed Grant. This program is designed to promote structured collaboration between UMBC and UMB and to advance the institutions’ joint goals in research and innovation.
posted Jun 05,2013
Proposals submitted to the program were evaluated using a peer review process that included faculty from both the UMB and UMBC campuses. Each proposal was reviewed for: (1) how well the project meets the goals of the Seed Grant Program; (2) meeting criteria (e.g., relevance to future public health concerns, significance, innovation, approach and qualification of investigative team/environment to carry out the aims); and (3) likelihood of attracting outside funding in the future. The grant recipients were chosen based on merit as assessed by peer review.
The funded proposal was:
Comparative Studies of the Intracellular Trafficking of Several Classes of Dendronized Drug Nanocarriers
UMBC PI: Marie-Christine Daniel, Chemistry and Biochemistry
UMB PI: Peter Swaan, Pharmaceutical Sciences
Congratulations to you both.

Jodian Brown and Brittny Davis have been awarded NIH's Ruth L. Kirschstein National Research Service Award (NRSA) Predoctoral Fellowship Award to Promote Diversity in Health-Related Research. The award consists of a stipend, partial tuition and an annual institutional allowance that can be used for scientific conferences and other expenses. Dr. Ruth L. Kirschstein, for whom the awards below were named, passed away on October 6, 2009. Aside from Dr. Kirschstein’s scientific accomplishments in polio vaccine development, and becoming the first woman director of an NIH Institute, she was a champion of research training and a strong advocate for the inclusion of underrepresented individuals in the scientific workforce.
Congratulations to both on a job well done!

We have just completed a significant upgrade of the 500 MHz NMR. This system was running an ancient (in computer years) and obsolete SGI computer which could not be easily replaced if it failed. The user software was old and could not be upgraded and the RF hardware was not amenable to the latest experiments. We now have a state-of-the-art console, with a new computer running the latest Bruker TopSpin software.
We are still using the same magnet and cryoprobe, which is optimized for proton detected experiments. Because of the higher magnet field and especially because the inner RF coil (used for protons) and the proton preamplifier are cooled to around 20 K we get excellent sensitivity in comparison to the Jeol 400 MHz. Proton sensitivity on the Jeol is approximately 300:1. During the upgrade of the 500 we obtained a proton sensitivity over 3500:1. Yes, that's at least 10x higher and since the required experiment time goes down as the square root of the sensitivity that's a very dramatic difference.
With the new console it is easier to do direct carbon detection (no cable changes required), but the cryoprobe is not at all optimal for this. Because of the great proton sensitivity and much higher information content of indirect detection experiments (HSQC, HMQC, HMBC, HSQC-Tocsy etc.) it makes a lot of sense to get your carbon information through these 2D experiments instead of doing direct 13C detection.
Improvements after the upgrade:
- Latest Bruker TopSpin software is more user friendly and capable.
- New computer with recent Linux operating system
- The latest state-of-the-art pulse sequences will run and are pre-installed to let you get very high information content from your experiments.
- RF hardware is more stable, clean and able to do sophisticated experiments
- Gradient shimming (TopShim) is much improved and easier to run to give excellent line shapes with minimal user effort
- Easier setup of experiments
The system, as before, does require a higher-level of care in operation than the Jeol. For example, the probe must be manually tuned for different solvents and this requires some attention to detail and the cryoprobe is an expensive and complex component of the instrument. For these reasons, please consider the experience level of your students before recommending they use the 500.
UMBC Graduate Isaac Kinde is part of a Johns Hopkins medical team that discovered that routine PAP smears can be used to screen for both ovarian and endometrial cancers. This discovery they hope eventually could reduce the number of deaths caused by the deadly malignancies. Their work made the cover of January 10th's issue of Science Translational Medicine and it has also attracted some attention from the general press. Congratulations to Isaac!
